The APIM does not respond to the diagnostic scan tool
For wiring diagram and connector information, REFER TO Wiring Diagrams Cell 14.
Normal Operation and Fault Symptoms
The APIM communicates on the HS-CAN, MS-CAN (touchscreen) and the Information and Entertainment Controller Area Network (I-CAN). The module communicates with the diagnostic scan tool on the Information and Entertainment Controller Area Network (I-CAN) through the gateway module on the HS-CAN. The IPC is the gateway module between the networks.
