B1D57
B1D57-ADJUSTABLE PEDAL SENSOR CIRCUIT HIGH
For a complete wiring diagram, refer to the Wiring Information.
- When Monitored:
Continuously.
- Set Condition:
If Voltage on the (G13) Adjustable Pedals Sensor Supply circuit is not within a specified range. The Memory Seat Module (MSM) will not be able to detect pedal position. When the Adjustable Pedals switch is pressed, the pedals will move for approximately two seconds then the module turns off the output.
1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. Using a scan tool, record and erase DTCs.
3. Cycle the ignition from on to off.
4. Turn the ignition on.
5. Operate the Adjustable Pedals switch in both positions then wait five seconds.
6. Using a scan tool read DTCs.
Does the scan tool display DTC B1D57-ADJUSTABLE PEDAL SENSOR CIRCUIT HIGH?
Yes
- Go To 2
No
- The conditions that caused this code to set are not present at this time. Perform the APS INTERMITTENT CONDITION TEST. Testing and Inspection.
2. CHECK THE (G13) ADJUSTABLE PEDALS SENSOR SUPPLY CIRCUIT FOR A SHORT TO VOLTAGE
1. Turn the ignition off.
2. Disconnect the Adjustable Pedals Motor harness connector.
3. Disconnect the MSM C2 harness connector.
NOTE: Check connectors. Clean and repair as necessary.
4. Turn the ignition on.
5. Measure the Voltage of the (G13) Adjustable Pedals Sensor Supply circuit between the Adjustable Pedals Motor harness connector and ground.
Is there any Voltage present?
Yes
- Repair the (G13) Adjustable Pedals Sensor Supply circuit for a short to Voltage.
- Perform the APS VERIFICATION TEST. APS Verification Test.
No
- Go To 3
3. CHECK THE (G13) ADJUSTABLE PEDALS SENSOR SUPPLY CIRCUIT FOR A SHORT TO THE (P205) ADJUSTABLE PEDALS MOTOR FORWARD CIRCUIT OR THE (P206) ADJUSTABLE PEDALS MOTOR REARWARD CIRCUIT
1. Turn the ignition off.
2. Disconnect the MSM C1 harness connector.
NOTE: Check connectors. Clean and repair as necessary.
3. Measure the resistance between the (G13) Adjustable Pedals Sensor Supply circuit and the (P205) Adjustable Pedals Motor Forward circuit at the Adjustable Pedals Motor harness connector.
4. Measure the resistance between the (G13) Adjustable Pedals Sensor Supply circuit and the (P206) Adjustable Pedals Motor Rearward circuit at the Adjustable Pedals Motor harness connector.
Is the resistance below 10K Ohms for either measurement?
Yes
- Repair all circuits with a resistance below 10K Ohms for a short to the (G13) Adjustable Pedals Sensor Supply circuit.
- Perform the APS VERIFICATION TEST. APS Verification Test.
No
- Go To 4
4. CHECK THE (G13) ADJUSTABLE PEDALS SENSOR SUPPLY CIRCUIT FOR AN OPEN
1. Measure the resistance of the (G13) Adjustable Pedals Sensor Supply circuit between the MSM C2 connector and the Adjustable Pedals Motor harness connector.
Is the resistance below 5.0 Ohms?
Yes
- Go To 5
No
- Repair the (G13) Adjustable Pedals Sensor Supply circuit for an open.
- Perform the APS VERIFICATION TEST. APS Verification Test.
5. CHECK THE (G493) POSITION SENSOR GROUND CIRCUIT FOR AN OPEN
1. Measure the resistance of the (G493) Position Sensor Ground circuit between the MSM C2 connector and the Adjustable Pedals Motor harness connector.
Is the resistance below 5.0 Ohms?
Yes
- Go To 6
No
- Repair the (G493) Position Sensor Ground circuit for an open.
- Perform the APS VERIFICATION TEST. APS Verification Test.
6. CHECK THE (G13) ADJUSTABLE PEDALS SENSOR SUPPLY CIRCUIT FUNCTION
1. Reconnect the MSM C1 harness connector.
2. Reconnect the MSM C2 harness connector.
3. Disconnect the scan tool.
4. Turn off all vehicle interior and exterior lighting.
5. Mark sure all doors are closed then wait 10 seconds.
6. Connect the positive lead of a voltmeter to the (G13) Adjustable Pedals Sensor Supply circuit and the negative lead to the (G493) Position Sensor Ground circuit at the Adjustable Pedals Motor harness connector.
7. While monitoring the voltmeter, press the Adjustable Pedals switch in either direction then release the switch.
Does the Voltage drop to 0 Volts after approximately 6 second?
Yes
- Replace the Adjustable Pedals Sensor.
- Perform the APS VERIFICATION TEST. APS Verification Test.
No
- Check the (G13) Adjustable Pedals Sensor Supply circuit for a short to Voltage from another circuit and repair as necessary. If circuit is okay, replace the Memory Seat Module (MSM).
- Perform the APS VERIFICATION TEST. APS Verification Test.
