The navigation interface module (NIM) communicates with the body control module (BCM) to receive odometer data via the GMLAN. When there is an error regarding data supplied, this DTC will set in the NIM.
The radio must detect one of the following power modes:
• | System voltage is between 9-16 volts. |
• | Engine is running. |
No change in the odometer pulse counter for 100 seconds while the vehicle is driven at speed above 40Km/h.
• | The condition for setting the DTC is no longer present. |
• | The DTC can be cleared using a scan tool. |
The odometer signal is provided via GMLAN message sent from the BCM, any corresponding set BCM DTCs should be tested prior to diagnosing DTC B1010 5A.
