Diagnostic Test

CHECK FOR A DTC B1D51-ADJUSTABLE PEDAL INHIBIT CIRCUIT OPEN
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, read and record DTCs.
3. With the scan tool, read and record Freeze Frame information.
4. With the scan tool, erase DTCs.
5. Cycle the ignition switch from off to on.
6. With the scan tool, read and record 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. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure
CHECK THE TERMINALS/CONNECTORS FOR DAMAGE
NOTE: Check all related wiring for bruised, chafed, pierced, or partially broken wires.

NOTE: Check all related connectors for broken, bent, pushed out, or corroded terminals.
1. Turn the ignition off.
2. Visually inspect the wiring for damage.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the APS VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure
  No
  - Go to step 3
SWAP OUT THE ADJUSTABLE PEDALS RELAY
1. Install a known good relay in place of the Adjustable Pedals Relay.
2. Turn the ignition on.
3. With the scan tool, erase DTCs.
4. Cycle the ignition switch from off to on.
5. With the scan tool, read and record DTCs
  Does the scan tool display this DTC as active?
  
  Yes
  - Go to step 4
  No
  - Replace the Adjustable Pedals Relay in accordance with the Service Information.
  - Perform the APS VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure
