B1D57

B1D57-ADJUSTABLE PEDAL SENSOR CIRCUIT HIGH





^ 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.

Possible Causes

- CONNECTOR/TERMINAL DAMAGE
- (G11) ADJUSTABLE PEDALS SENSOR SUPPLY CIRCUIT SHORTED TO VOLTAGE
- (G12) ADJUSTABLE PEDALS SENSOR SIGNAL CIRCUIT SHORTED TO
- VOLTAGE ADJUSTABLE PEDALS SENSOR - INTERNAL FAULT
- SEAT MEMORY MODULE - INTERNAL FAULT

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.
Perform APS VERIFICATION TEST - VER 1. Verification Tests

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 - VER 1. Verification Tests
No >> Go To 3

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





Turn the ignition off.
Disconnect the Seat Memory Module harness connector.
Turn the ignition on.
Measure the voltage between the (G11) Adjustable Pedals Sensor
Supply circuit and ground.
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 - VER 1. Verification Tests
No >> Go To 4

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





Turn the ignition off.
Disconnect the Seat Memory Module harness connector.
Turn the ignition on.
Measure the voltage between the (G12) Adjustable Pedals Sensor Signal circuit and ground.
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 - VER 1. Verification Tests
No >> Go To 5

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





Turn the ignition off.
Reconnect all connectors.
Measure the voltage of the (G12) Adjustable Pedals Sensor Signal circuit in the Seat Memory Module harness connector.
Is the voltage below 4.0 volts?
Yes >> Replace and reprogram the Seat Memory Module in accordance with the Service Information.
Perform APS VERIFICATION TEST - VER 1. Verification Tests
No >> Replace the Adjustable Pedals Sensor in accordance with the Service Information.
Perform APS VERIFICATION TEST - VER 1. Verification Tests
