FCM - Ambient Temp Configuration Error

FCM - AMBIENT TEMP CONFIGURATION ERROR

WHEN MONITORED
During power up.

SET CONDITION
The FCM detects that an Ambient Temperature Sensor is present on the input circuit and has gone through auto-configuration and another module is transmitting a redundant ambient temp message.

POSSIBLE CAUSES
- Incorrect configuration

Diagnostic Test

1. INCORRECT CONFIGURATION

NOTE:
- This code will only set if the FCM detects that another module transmitting a redundant ambient temp message.
- Diagnose and repair any Communication DTCs before proceeding with this test.

Ensure that the vehicle has only one Ambient Temperature Sensor, and that it is hardwired to the FCM.
With the DRBIII(R), erase DTCs.
Cycle the ignition to auto-configure the FCM.
With the DRBIII(R), read DTCs.

Q: Did this DTC reset?

YES: Ensure that the vehicle is not equipped with multiple Ambient Temperature Sensors. If vehicle is equipped with NGC, disconnect the ambient temp sensor to the FCM and cycle the ignition. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Replace and program the Front Control Module. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
