B1D57-ADJUSTABLE PEDAL SENSOR CIRCUIT HIGH





For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
The Adjustable Pedal Motor is in active operation.

- Set Condition:
The Seat Memory Module detects a high signal circuit voltage that is not within voltage specification from the Adjustable Pedal Sensor.





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 DTCs.
Cycle the ignition switch from off to on.
Cycle the Adjustable Pedals Switch forward and rearward.
With the scan tool, read DTCs.
Does the scan tool display: B1D57-ADJUSTABLE PEDAL SENSOR CIRCUIT HIGH?

Yes

- Go To 2

No

- Refer to the INTERMITTENT CONDITION diagnostic procedure. Checking For An Intermittent DTC.
- PERFORM APS VERIFICATION TEST. APS Verification Test

2. CHECK CONNECTOR/TERMINAL FOR DAMAGE

NOTE: Check all terminals for broken, bent, pushed out, or corroded terminals.

Turn the ignition off.
Inspect the Seat Memory Module harness connector, Adjustable Pedals Sensor, and Adjustable Pedals Sensor harness connector.
Is the Adjustable Pedals Sensor or any of the connectors/terminals damaged?

Yes

- Repair as necessary.
- PERFORM APS VERIFICATION TEST. APS Verification Test

No

- Go To 3

3. CHECK (G11) ADJUSTABLE PEDALS SENSOR SUPPLY CIRCUIT FOR A SHORT TO VOLTAGE




Disconnect the Seat Memory Module harness connector.
Turn the ignition on.
Measure the voltage between the (G11) Adjustable Pedals Sensor Supply circuit and ground at the Memory Seat Module C1 harness connector.
Is the voltage above 5.0 volts?

Yes

- Repair the (G11) Adjustable Pedals Sensor Supply circuit for a short to voltage.
- PERFORM APS VERIFICATION TEST. APS Verification Test

No

- Go To 4

4. CHECK (G12) ADJUSTABLE PEDALS SENSOR SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE




Measure the voltage between the (G12) Adjustable Pedals Sensor Signal circuit and ground at the Memory Seat Module C1 harness connector.
Is the voltage above 5.0 volts?

Yes

- Repair the (G12) Adjustable Pedals Sensor Signal circuit for a short to voltage.
- PERFORM APS VERIFICATION TEST. APS Verification Test

No

- Go To 5

5. CHECK (G12) ADJUSTABLE PEDALS SENSOR SIGNAL CIRCUIT VOLTAGE




Measure the voltage of the (G12) Adjustable Pedals Sensor Signal circuit at the Seat Memory Module C1 harness connector.
Is the voltage below 4.0 volts?

Yes

- Replace and reprogram the Seat Memory Module.
- PERFORM APS VERIFICATION TEST. APS Verification Test

No

- Replace the Adjustable Pedals Sensor.
- PERFORM APS VERIFICATION TEST. APS Verification Test
