Diagnostic Test

CHECK FOR DTC B1D56-ADJUSTABLE PEDAL SENSOR CIRCUIT LOW
NOTE: This DTC must be active for the results of this test to be valid.
1. Turn the ignition on.
2. With the scan tool, record and erase DTCs.
3. Cycle the ignition switch from off to on.
4. Cycle the Adjustable Pedals Switch forward and rearward.
5. With the scan tool, read DTCs.
  Does the scan tool display this DTC as active?
  
  Yes
  - Go to step 2
  No
  - The condition that caused the symptom is currently not present. Inspect the related wiring for a possible intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires.
  - Refer to the APS INTERMITTENT CONDITION TEST. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure
CHECK CONNECTOR/TERMINAL FOR DAMAGE
NOTE: Check all terminals for broken, bent, pushed out, or corroded terminals.
1. Turn the ignition off.
2. Inspect the Memory Seat Module C1 harness connector and Adjustable Pedals Motor harness connector.
  Is there any connector or terminal damaged?
  
  Yes
  - Repair as necessary.
  - Perform the APS VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure
  No
  - Go to step 3
