B3606

DTC B3606

CIRCUIT DESCRIPTION
The driver seat module (DSM) monitors the location of the adjustable pedals using the brake pedal position sensor. The brake pedal position sensor is supplied with 5-volt reference and ground circuits from the DSM. The position sensor signal circuit is referenced from ground within the DSM. The signal voltage monitored by the DSM ranges from 0.39-4.58 volts and is determined by the wiper location on the resistor within the position sensor. The position sensor circuit voltage level is used by the DSM to determine the position of the adjustable pedals when storing or recalling memory position settings.

DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC B3606 Adjustable Foot Pedal Position Sensor Circuit

CONDITIONS FOR RUNNING THE DTC
Battery voltage to the seat module must be within 7-16 volts.

CONDITIONS FOR SETTING THE DTC
The position sensor signal circuit voltage level to the DSM is not within the 0.39-4.58 volt range.

ACTION TAKEN WHEN THE DTC SETS
The memory recall functions will be disabled for as long as the DTC is current.

CONDITIONS FOR CLEARING THE DTC
- The DTC will be stored as a history code when the fault is no longer present.
- A history DTC will be cleared after completing 100 consecutive ignition cycles, or by using the scan tool clearing DTCs feature.

DIAGNOSTIC AIDS
If the DTC is only found in history, the fault may be intermittent.

TEST DESCRIPTION

Step 1 - Step 9:

Step 10 - Step 15:

The numbers below refer to the step numbers on the diagnostic table.
3. This step tests for the proper operation of the circuit in the low voltage range.
4. This step tests for the proper operation of the circuit in the high voltage range. If the fuse in the jumper opens if you perform this test, the signal circuit is short to ground.
5. This step tests for a short to voltage in the 5-volt reference circuit.
