Yes
>> Go To 8
No
>> Replace and reprogram the Memory Seat Module in accordance with the Service Information.
Perform APS VERIFICATION TEST - VER 1.
8.
CHECK ADJUSTABLE PEDALS SENSOR SIGNAL CIRCUIT VOLTAGE
Measure the voltage of the Adjustable Pedals Sensor Signal circuit in the Memory Seat Module harness connector.
Is the voltage above 0.5 volts?
Yes
>> Replace and reprogram the Memory Seat Module in accordance with the Service Information.
Perform APS VERIFICATION TEST - VER 1.
No
>> Replace the Adjustable Pedals Sensor in accordance with the Service Information.

Diagnostic Test
1.
CHECK FOR DTC B1D57–ADJUSTABLE PEDAL SENSOR CIRCUIT HIGH
NOTE: This DTC must be active for the results of this test to be valid.
Turn the ignition on.
With the scan tool, record and erase DTC’s.
Cycle the ignition switch from off to on.
Cycle the Adjustable Pedals Switch forward and rearward.
With the scan tool, read DTC’s
Does the scan tool display: B1D57–ADJUSTABLE PEDAL SENSOR CIRCUIT HIGH?
Yes
>> Go To 2
No
>> Refer to the INTERMITTENT CONDITION diagnostic procedure.
Perform APS VERIFICATION TEST - VER 1.
2.
CHECK CONNECTOR/TERMINAL FOR DAMAGE
NOTE: Check all terminals for broken, bent, pushed out, or corroded terminals.
Turn the ignition off.
Inspect the Memory Seat Module harness connector and the Adjustable Pedal Motor harness connector.
Is there any connector or terminal damaged?
Yes
>> Repair as necessary.
Perform APS VERIFICATION TEST - VER 1.
No
