Malfunction of power door lock
NOTE:• When each door can not be locked in interlocking with
the door lock button at driver’s seat, proceed to the fol-lowing checks.
(1) Check to see if the tail fuse (40 A) or door lock fuse(15 A) has open wire.
(2) Turn off the ignition switch. Disconnect the ITC ECUconnector from the connector at the vehicle wire har-ness side.
BE–12 Revised on ’98 Oct.
(3) With a circuit tester set to the voltmeter range, connectthe circuit tester to between the terminal +B of theconnector at the vehicle wire harness side and thebody earth, as shown in the figure. Check to see if thebattery voltage is applied.
NOTE:• The battery voltage is applied to this terminal at all
times regardless of the ON/OFF state of the ignitionswitch.
(4) With a circuit tester set to the ohmmeter range, con-nect the circuit tester to between the terminal UKS ofthe connector at the vehicle wire harness side and thebody earth, as shown in the figure. Check to see ifcontinuity exists.
NOTE:• This terminal has no continuity when the door lock but-
ton at driver’s seat is locked. Conversely, this terminalhas continuity when the door lock button at the driver’sseat is not locked.
• If this check reveals abnormality, check the door lockcontrol switch and wire harness.
(5) With a circuit tester set to the ohmmeter range, con-nect the circuit tester to the terminals between the ter-minal LKS of the connector at the vehicle wire harnessside and the body ground, as shown in the figure.Check to see if continuity exists.
NOTE:• This terminal has no continuity when the door lock but-
ton at driver’s seat is locked. Conversely, this terminalhas continuity when the door lock button is locked.
• If the check reveals any abnormality, check the doorlock control switch and wire harness.
(6) Connect the ITC ECU connector with the connector atthe vehicle wire harness side. (Connect the connec-tors that were disconnected at Step (2) into the originalpositions.)
(7) Disconnect the door lock motor connector at the doorside whose locking is inoperative from the connectorat the vehicle wire harness side. Connect a circuittester in its voltmeter mode, as shown in the figure.

(8) Turn on the ignition switch and lock or unlock the doorlock button at the driver’s seat. Check to see if the volt-meter registers the battery voltage. If there is abnor-mality, check the wire harness.
NOTE:• The current during the locking state flows in the re-
verse direction, as opposed to the current during theunlocking state.
(9) If there is no abnormality in the check at Step (8),apply the battery voltage directly to the door lockmotor terminal to see if the door lock functions.
CAUTION:• Never let the current flow for ten seconds or more con-
tinuously.
NOTE:• If the lock motor has no abnormality, the ITC ECU is re-
garded as faulty. Replace the ITC ECU.

AIR CONDITIONERThe genuine air conditioner of the TERIOS employs a sub-cooling cycle system. Therefore, this section introduces theproper replenishing procedure for the refrigerant gas.In the case of the hitherto-employed receiver cycle, it was im-possible to attain the 100 % liquidation of the evaporated re-frigerant gas. As a result, a part of the refrigerant was sent to the evaporatorin a gas state.To solve this problem, a sub-cool condenser has been em-ployed.In the new design, the condenser incorporates an condensingsection, a modulator and an over-cooling section (sub-coolingsection). Thus, the evaporated refrigerant undergoes the liqui-dation process twice, thus making it possible to attain a nearly100 % liquidation.Furthermore, the modulator functions in such a way that theliquid is separated from the gas. No receiver is provided inthe sub-cooling cycle.
REPLENISHING PROCEDURE1. The gas replenishment must be carried out, until such a
time when bubbles no longer appear at the sight glass.2. Another 100 g of the gas should be charged after the time
when bubbles no longer appear at the sight glass.
CAUTION:• Never stop replenishing gas at a time when bubbles
disappear at the sight glass.Even if additional charging of gas is made for a littlewhile, it will not result in adequate charging.
NOTE:• In the case of the sub-cooling cycle, the bubble disap-
pearing point is located before the cooling ability stabi-lizing zone.Therefore, it is necessary to continue replenishing gasbeyond the bubble disappearing point.
SPECIFICATION:• Charging amount of refrigerant: 400 ± 30 g

SRS AIR BAG SYSTEMThe SRS air bag system of the new TERIOS has been totallychanged from the system with the hitherto-employed specifi-cations. This time, the new TERIOS has employed the air bagsystem with the seat belt pretensioner, as is the case with theSirion.
BE–16 Revised on ’98 Oct.
IMPORTANT SAFETY NOTICE
WARNING:• Make certain to perform operations of the air bag sys-
tem according to the correct procedure and method.Failure to observe this notice may cause the air bagsystem to operate unexpectedly during the service op-eration, resulting in serious accidents. Furthermore, ifwrong repairs should be performed, there are the pos-sibilities that the air bag system fail to operate when re-quired.
• Before servicing the air bag components or the seatbelt pretensioner device, perform the following proce-dures: (1) Check the status of air bag warning lamp.(2) Read the diagnosis codes and put it on record.(3) Turn OFF the ignition switch and detach the nega-
tive (–) terminal of the battery cable. Then, wait forat least 90 seconds to prevent the air bag from thedeployment.
• It should be noted that, when the negative (–) terminalof the battery is detached, the memory of the ECU con-trol of the other system will be erased at the same time.
• Never bring your face, arms and body to the front ofthe air bag unit during the removal.
• Be sure to place the removed air bag pad assemblywith the pad surface facing upward. The assembly withthe pad surface facing downward is potentially hazard.Failure to observe this warning may cause unexpecteddeployment of the air bag, resulting in scattered padassembly.
• Furthermore, store the pad assembly and seat belt pre-tensioner device at a low place close to the groundlevel where no heat source (85°C or more) exists inclose proximity, and store at a place where is not ex-posed to direct sun rays.

• If the air bag components or seat belt pretensioner de-vice are dropped, be sure to dispose of the unit accord-ing to the disposal procedure. Be sure to mount a newunit to the vehicle.
• During installation or replacement, do not bump thearea near the air bag ECU, using an impact wrench, ahammer or the like. It may cause the sensor in theECU to operate.
• To prevent the air bag or the pretensioner from deploy-ing, do not measure the resistance of the inflator squibeasily.The squib of the air bag or seat belt pretensioner con-sists of a filament of about 2 ohms. Therefore, there isthe possibility that a current which is big enough tocause deployment flows when ohmmeter is connected.
• Do not overhaul the air bag components and the seatbelt pretensioner device. It has no serviceable parts.
• Do not install used air bag components and seat beltpretensioner device from another car. When repairing,use only new components.

(1) Terminal double locking mechanismThis mechanism is provided with all connectors of this system.The connector is of a two-piece construction consisting of aterminal housing and a spacer. The terminal holding is dou-ble-locked by the lance in the housing (primary one) and thespacer (secondary one).
(2) Terminal short mechanismThis mechanism is provided at the connector between theECU and the inflator squib.A short spring is provided inside the connector. When theconnector is disconnected, the terminals in the squib sideconnector are shorted automatically, thereby preventing gen-eration of a potential difference between both terminals.
(3) Connector double locking mechanismThis mechanism is provided at the steering roll connector andconnectors to each squib.For improved reliability of connection, connectors (male andfemale) are double locked with each other. It is so constructedthat, when the primary lock is not made, the secondary lockcan not be made because a protrusion hinders the locking.
(4) Incomplete fitting detecting mechanismThis mechanism is provided at the connector for air bag ECU.This mechanism detects electrically if the connector is con-nected completely. When the connector is fit completely, thedetecting terminals at the ECU side and detecting pins at har-ness connector side are connected, allowing a small amountof current to flow to the ECU and warning lamp circuit. In thisway, the fitting condition is monitored.If the connector is connected incompletely, the detecting pinsand terminals don’t contact.

DIAGNOSIS CHECK<Confirmation procedure for diagnosis codes>1. Turn ON the ignition switch.2. If the air bag warning lamp goes on for six seconds and
goes out afterward, the system is functioning properly.NOTE:• If the lamp will not go on at this time, refer to page
BE–32.
3. If the warning lamp keeps illuminated for more than sixseconds, it means a certain system malfunctioning isbeing detected. Proceed to the following operations.
4. Connect the test terminal (ECU-T) and the earth terminal(E) with a jump wire.
5. Confirm the diagnosis code by reading the number offlashing of the combination lamp.
<Reading of diagnosis codes>When two or more malfunction codes are outputted, thecodes are indicated in the sequence of the code numbers,starting from a smaller number, with a four-second distin-guished period interposed between codes.After a lapse of four seconds, the malfunction codes are indi-cated by the repetition of a 0.5-second glowing period and a0.5-second extinguished period. If the code is a two-digitnumber, the 1.5-second extinguished period is interposed be-tween the units digit and the tens digit.
<Canceling procedure for records of diagnosis codes>1. The diagnosis codes can be canceled by connecting re-
peatedly the test terminal (ECU-T) with the earth terminal(E) at the intervals shown in the figure.
2. When the malfunction has been remedied and the systemhas resumed, the normal code shown in the figure is indi-cated.NOTE:• The cancellation procedure for the malfunction record
can not be applied to the cancellation of the record ofthe malfunction for the ECU internal circuit.(Diagnosis code numbers 61 and 62)

NOTE:• As regards the removal and installation procedures for
the air bag related parts, refer to page BE–22 - 32 ofthis service manual.
Inspection1. Turn OFF the ignition switch and detach the negative (–)
terminal of the battery cable. Then wait for at least 90 sec-onds.
2. Disconnect the connector from the air bag ECU.NOTE:• When the connector is disconnected from the air bag
ECU, the connector terminals T11 (DB+) and T12(DB–) at the cowl wire harness side are shorted auto-matically by the short circuit bridge.
3. Remove the steering pad assembly (air bag unit) from thesteering wheel.
4. Disconnect the pad assembly connector from the roll con-nector.
5. Ensure that the continuity exists between the respectiveterminals.
Between Terminal F2 (+) and G2 (–):Continuity exists.
6. If there is no continuity, it is necessary to know whether thefaulty point is attributable to the inside of the roll connec-tor. To this end, disconnect the coupling connector of theroll connector and the cowl wire. Then, check the continu-ity of each parts. If an open wire is found, replace thefaulty part with a new one.
7. If there is no open wire, connect both ends of the roll con-nector terminals with a jump wire to short them.
8. Connect the connector at the cowl wire harness side and theair bag ECU connector that were disconnected at Step 2.
9. Connect the battery negative (–) cable.10. Turn ON the ignition switch and take a reading of the diag-
nosis code.CAUTION:• If the code 24 (short circuit of squib circuit) is indicated,
it proves indirectly that there is open wire in the squibof the steering pad assembly (air bag unit). Therefore,replace the steering pad assembly.
11. After the inspection and installation, cancel the diagnosiscode and confirm that the code 21 and 24 are not out-putted any more.
