NOTE: Both front height sensors share a common reference voltage circuit and a common signal groundcircuit, both rear height sensors also share a common voltage circuit and common ground circuit. Because ofthis, an internal short inside one sensor of a pair of sensors (front or rear) affects both sensors, causing theVDM to set a DTC for both height sensors.



Connect: Suspect Height Sensor .

Ignition ON.

Using a diagnostic scan tool, monitor the following PIDs:Left Front Height Sensor Voltage (LF_Hght_Sens)Right Front Height Sensor Voltage (RF_Hght_Sens)Left Rear Height Sensor Voltage (LR_Hght_Sens)Right Rear Height Sensor Voltage (RR_Hght_Sens)

If DTC C1A03:xx or C1A04:xx is present, disconnect left front height sensor C1153 and monitor theRF_Hght_Sens PID.

If DTC C1A05:xx or C1A06:xx is present, disconnect left rear height sensor C3653 and monitor theRR_Hght_Sens PID.

Does the right side PID value change when the left side connector is disconnected?

Yes The left height sensor is shorted internally, INSTALL a new left side height sensor. REFER toSuspension Height Sensor — Front or Suspension Height Sensor — Rear.

No The right height sensor is shorted internally, INSTALL a new right side height sensor. REFER toSuspension Height Sensor — Front or Suspension Height Sensor — Rear.

Pinpoint Test J: U0151:87

Diagnostic Overview




With the ignition ON, the RCM sends the VDM messages over a private HS-CAN . If the VDM not receive thesemessages within a certain time frame, the module sets DTCs.



U0151:87Lost CommunicationWith RCM : MissingMessage

This DTC sets in continuous memory if any one of the followingmessages is missing; yaw rate, lateral acceleration, longitudinalacceleration or roll rate.
