1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.
Visual Inspection Chart
3. If the fault is visually evident, correct the cause (if possible) before proceeding to the next step.
NOTE: Make sure to use the latest scan tool software release.
4. If the cause is not visually evident, connect the scan tool to the data link connector (DLC).
NOTE: The vehicle communication module (VCM) LED prove-out confirms power and ground from the data link connector (DLC) are provided to the
VCM.
5. If the scan tool does not communicate with the VCM:
-
Check the VCM connection to the vehicle.
-
Check the scan tool connection to the VCM.
-
See See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Pinpoint Tests/CAN Communication
Network/Pinpoint Test 1: The PCM Does Not Respond To The Scan Tool Or No High Speed Controller Area Network (HS-CAN)
Communication, to diagnose no communication with the scan tool.
6. If the scan tool does not communicate with the vehicle:
-
Verify the ignition key is in the ON position.
-
Verify the scan tool operation with a known good vehicle.
-
See See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Pinpoint Tests/CAN Communication
Network/Pinpoint Test 1: The PCM Does Not Respond To The Scan Tool Or No High Speed Controller Area Network (HS-CAN)
Communication, to diagnose no response from the PCM.
NOTE: Do not press any buttons on the front controls interface module (FCIM) while the ACM is carrying out the self-test.
7. Carry out the network test.
-
If the scan tool responds with no communication from one or more modules, see - See: Powertrain Management/Computers and Control
Systems/Testing and Inspection/Initial Inspection and Diagnostic Overview/Communications Network - Troubleshooting.
-
If the network test passes, retrieve and record the continuous memory DTCs.
8. Clear the continuous DTCs and carry out the Navigation Audio Control Module (ACM) Self-Diagnostics.
9. If the DTCs retrieved are related to the concern, see - See: Powertrain Management/Computers and Control Systems/Testing and
Inspection/Diagnostic Trouble Code Descriptions/Navigation System DTC Chart.
10. If no DTCs related to the concern are retrieved, see -- See: Symptom Related Diagnostic Procedures.
