B1034-INFRARED TEMPERATURE SENSOR INPUT CIRCUIT LOW

For a complete wiring diagram refer to Diagrams/Electrical.

Theory of Operation

The CMTC receives data from the IR Sensor by means of a dedicated circuit. In turn, the CMTC busses the IR Sensor data to the A/C Heater Control by means of the Controller Area Network (CAN) B Bus. The A/C Heater Control requires IR Sensor data to function in an automatic mode.

- When Monitored:

With the ignition on.

- Set Condition:

If the Compass Temperature Module (EOM) detects a short to ground on the (C38) Infrared Sensor Signal circuit.
