Accessory Protocol Interface Module (APIM)
ACCESSORY PROTOCOL INTERFACE MODULE (APIM) DTC CHART
| DTC | Description | Action |
|---|---|---|
| B1201:1C | Steering Wheel Audio Switch Pack 2: Circuit Voltage Out of Range | GO to PINPOINT TEST D . |
| B1201:63 | Steering Wheel Audio Switch Pack 2: Circuit/Component Protection Time-Out | GO to PINPOINT TEST D . |
| B1252:04 | USB Port: System Internal Failure | GO to PINPOINT TEST J . |
| B1252:11 | USB Port: Circuit Short to Ground | GO to PINPOINT TEST J . |
| B1D79:01 | Microphone Input: General Electrical Failure | GO to PINPOINT TEST E . |
| U2100:00 | Initial Configuration Not Complete: No Sub Type Information | CHECK vehicle service history for recent service actions related to this module. This DTC sets due to incomplete or incorrect PMI procedures. If there have been recent service actions with this module, REPEAT/PERFORM the PMI procedure as directed by the scan tool. If there have been no recent service actions, REFER to APIM HARDWARE TESTING . |
| U2101:00 | Control Module Configuration Incompatible: No Sub Type Information | CHECK vehicle service history for recent service actions related to this module. This DTC sets due to incomplete or incorrect PMI procedures. If there have been recent service actions with this module, REPEAT/PERFORM the PMI procedure as directed by the scan tool. If there have been no recent service actions, REFER to APIM HARDWARE TESTING . |
| U3000:04 | Control Module: System Internal Failure | GO to PINPOINT TEST K . |
| U3000:41 | Control Module: General Checksum Failure | CLEAR the DTCs. REPEAT the self-test. If DTC U3000:41 is still present, REFER to APIM HARDWARE TESTING . |
| U3000:42 | Control Module: General Memory Failure | CLEAR the DTCs. REPEAT the self-test. If DTC U3000:42 is still present, REFER to APIM HARDWARE TESTING . |
| U3000:88 | Control Module: Bus Off |
NOTE:
Network communication/message DTCs may result from intermittent concerns with damaged wiring or low battery voltage. Additionally, vehicle repair procedures such as module reprogramming often set these DTCs. To avoid repeat network concerns, inspect for damaged or corroded wiring at the APIM. Test the vehicle battery; Refer to
PINPOINT TEST A: BATTERY CONDITION TEST
. Refer to
CHARGING SYSTEM
for more information. Replacing a module to resolve a network DTC is unlikely to resolve the concern. The module could not communicate on the network at a point in time. The fault is not currently present. CLEAR the DTC. REPEAT the network test with the scan tool. |
| U3003:16 | Battery Voltage: Circuit Voltage Below Threshold | GO to PINPOINT TEST L . |
| U3003:17 | Battery Voltage: Circuit Voltage Above Threshold | GO to PINPOINT TEST M . |
