Inspection and Verification - Adjustable Pedals With Memory Feature
1. Verify the customer concern by operating the adjustable pedals.

NOTE: If the adjustable pedals are not installed on the vehicle, when a self-test is carried out, the driver seat module (DSM) will set pedal codes.

2. Visually inspect for obvious signs of mechanical or electrical damage. Refer to the following chart:

Visual Inspection Chart:

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

4. NOTE: Make sure to use the latest scan tool software release.

If the cause is not visually evident, connect the scan tool to the data link connector (DLC).

5. NOTE: The vehicle communication module (VCM) LED prove out confirms power and ground from the DLC are provided to the VCM.

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.
^ refer to Information Bus (Module Communications Network) 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.
^ refer to Information Bus (Module Configuration) to diagnose no response from the PCM.
7. Carry out the network test.
^ If the scan tool responds with no communication for one or more modules, refer to Information Bus (Multiplex Communications Network).
^ If the network test passes, retrieve and record continuous memory DTCs.
8. Clear the continuous DTCs and carry out the self-test diagnostics for the DSM.
9. If the DTCs retrieved are related to the concern, go to the Driver Seat Module (DSM) DTC Chart. For all other DTCs, refer to the Master DTC Chart in Body Control Systems (Multifunction Electronic Control Module). Diagnostic Trouble Code Tests and Associated Procedures
10. If no DTCs related to the concern are retrieved, GO to Symptom Chart - Adjustable Pedals With Memory Feature. Symptom Chart - Adjustable Pedals With Memory Feature
