Circuit/System Description
The memory seat module (MSM) monitors the location of the adjustable pedals using the adjustable pedals position sensor. The adjustable pedals position sensor is supplied with 5-volt reference and ground circuits from the MSM. The position sensor signal circuit is referenced from ground within the MSM. The signal voltage monitored by the MSM ranges from 0.45-4.55 volts.
Conditions for Running the DTC
System voltage to the MSM must be 9-16 volts.
Conditions for Setting the DTC
The position sensor input to the MSM is not within the 0.45-4.55 volt range.
Action Taken When the DTC Sets
Memory recall functions will be suspended.
Conditions for Clearing the DTC
| • | The DTC becomes history when the conditions for setting the DTC are no longer present. |
| • | The history DTC clears after 100 malfunction-free ignition cycles. |

Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the adjustable pedal motor.
- Ignition OFF, test for less than 10 ohm between the low reference circuit terminal 3 and ground.
- Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal 1 and ground.
- Verify the scan tool Pedal Position parameter is less than 0.45 volt.
- Install a 3A fused jumper wire between the signal circuit terminal 2 and the 5-volt reference circuit terminal 1. Verify the scan tool Pedal Position parameter is greater than 4.55 volts.
- If all circuits test normal, test or replace the adjustable pedal motor.
| ⇒ | If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the MSM. |
| ⇒ | If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the MSM. |
| ⇒ | If greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the MSM. |
| ⇒ | If greater than the specified range, test the signal circuit terminal 2 for a short to voltage. If the circuit tests normal, replace the MSM. |
| ⇒ | If less than the specified range, test the signal circuit for short to ground or an open/high resistance. If the circuit tests normal, replace the MSM. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
