Pinpoint Test - DTC: AL

B00C2:11 and B00C2:12

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The Belt Tension Sensor (BTS) operates in conjunction with the OCS. The OCSM provides a reference voltage to the Belt Tension Sensor (BTS), which changes as it passes through the sensor, based on how much tension is applied to the safety belt and Belt Tension Sensor (BTS).

The OCSM monitors the Belt Tension Sensor (BTS) reference voltage circuit for a short to voltage or a short to ground.

If a fault is detected, the OCSM stores DTC B00C2:11 or B00C2:12 in memory and sends a message to the RCM over the HS-CAN2 indicating that an OCS fault is present. Upon receipt of this message, the RCM sets DTC B00A0:09 and sends a message to the IPC to illuminate the airbag warning indicator.

PINPOINT TEST A : B00C2:11 AND B00C2:12

WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System (SRS) deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment.

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
