1. 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 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. Testing and Inspection

2. CHECK CONNECTOR/TERMINAL FOR DAMAGE
