DTC Descriptors
DTC B3606 01
- Adjustable Foot Pedal Position Sensor Circuit Short to Battery

DTC B3606 06
- Adjustable Foot Pedal Position Sensor Circuit Short to Ground or Open

Diagnostic Fault Information






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

1. Ignition OFF, disconnect the harness connector at the adjustable pedal motor.
2. Ignition OFF, test for less than 10 ohm between the low reference circuit terminal 3 and ground.

• If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the MSM.

3. Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal 1 and ground.

• 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.

4. Verify the scan tool Pedal Position parameter is less than 0.45 volt.

• 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.

5. 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 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.

6. If all circuits test normal, test or replace the adjustable pedal motor.
