B1D56
B1D56-ADJUSTABLE PEDAL SENSOR CIRCUIT LOW
For a complete wiring diagram, refer to the Wiring Information.
- When Monitored:
Continuously.
- Set Condition:
The 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. CHECK FOR ACTIVE FAULT WITH PEDALS STATIONARY
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. Using a scan tool, read DTCs.
Does the scan tool display DTC B1D56-ADJUSTABLE PEDAL SENSOR CIRCUIT LOW?
Yes
- Go To 3
No
- Go To 2
2. CHECK FOR ACTIVE FAULT WHILE ADJUSTING THE PEDALS
1. Operate the Adjustable Pedals switch in both positions then wait five seconds.
2. Using a scan tool, read DTCs.
Does the scan tool display DTC B1D56-ADJUSTABLE PEDAL SENSOR CIRCUIT LOW?
Yes
- Go To 3
No
- The conditions that caused this code to set are not present at this time. Perform the APS INTERMITTENT CONDITION TEST. Testing and Inspection.
3. CHECK THE (G13) ADJUSTABLE PEDALS SENSOR SUPPLY CIRCUIT FOR A SHORT TO GROUND
1. Turn the ignition off.
2. Disconnect the MSM C2 harness connector.
3. Disconnect the Adjustable Pedals Motor harness connector.
NOTE: Check connectors. Clean and repair as necessary.
4. Measure the resistance of the (G13) Adjustable Pedals Sensor Supply circuit between ground and the Adjustable Pedals Motor harness connector.
Is the resistance below 10K Ohms?
Yes
- Repair the (G13) Adjustable Pedals Sensor Supply circuit for a short to ground.
- Perform APS VERIFICATION TEST. APS Verification Test.
No
- Go To 4
4. CHECK THE (G13) ADJUSTABLE PEDALS SENSOR SUPPLY CIRCUIT FOR A SHORT TO THE (G493) POSITION SENSOR GROUND CIRCUIT, THE (P205) ADJUSTABLE PEDALS MOTOR FORWARD CIRCUIT, OR THE (P206) ADJUSTABLE PEDALS MOTOR REARWARD CIRCUIT
1. Measure the resistance between the (G13) Adjustable Pedals Sensor Supply circuit and the (G493) Position Sensor Ground circuit at the Adjustable Pedals Motor harness connector.
2. 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.
3. 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 any 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 5
5. CHECK THE (G13) ADJUSTABLE PEDALS SENSOR SUPPLY AND (G493) POSITION SENSOR GROUND CIRCUIT FUNCTION
1. Reconnect the MSM C2 harness connector.
2. Disconnect the scan tool.
3. Turn off all vehicle interior and exterior lighting.
4. Mark sure all doors are closed then wait 10 seconds.
5. Connect a 12-Volt test light between the (G13) Adjustable Pedals Sensor Supply circuit and the (G493) Position Sensor Ground circuit at the Adjustable Pedals Motor harness connector.
6. While monitoring the test light, press the Adjustable Pedals switch in either direction then release the switch.
Does the test light illuminate for approximately six seconds then turn off?
Yes
- Replace the Adjustable Pedals Sensor.
- Perform the APS VERIFICATION TEST. APS Verification Test.
No
- Replace the Memory Seat Module (MSM).
- Perform the APS VERIFICATION TEST. APS Verification Test.
