A037

Wiring Diagram:

CIRCUIT DESCRIPTION

Code A037 will set if the ignition is on and the ACP has lost data communication with the Instrument Panel Cluster (IPC). This code should be seen only as a 'History' code (if communications are currently inoperative the ACP will not be able to communicate with the IPC to display the trouble code).

Diagnosis of this code is dependent upon other system symptoms (trouble codes) present with A037.

A037 and 1037

Code 1037, Loss of ACP Data, may be present with this code. If so, this would indicate that both the IPC and ACP were functional when the code set, but they could not communicate with one another. Refer to the diagnostic chart for Multiple Data Communications Codes In (IPC) for this condition. Instrument Panel, Gauges and Warning Indicators

A037 and I052 (and E047)

Code 1052, IPC Loss of Memory, may be present with this code. If so, this would indicate that the IPC experienced a memory reset condition (lost battery or was interrupted in some other way) and temporarily quit communicating with the other major computers. If this combination is present, Code P047, Loss of IPC Data, may also be stored history. Refer to the diagnostic chart for I052. Instrument Panel, Gauges and Warning Indicators
