B3606

DTC B3606

CIRCUIT DESCRIPTION
The driver seat module 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 driver seat module. The position sensor signal circuit is referenced from ground within the driver seat module. The signal voltage monitored by the driver seat module 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 driver seat module to determine the position of the adjustable pedals when storing or recalling memory position settings.

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 driver seat module 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

Steps 1-5:

Steps 6-15:

The numbers below refer to the step numbers on the diagnostic table.
3. Tests for the proper operation of the circuit in the low voltage range.
4. 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. Tests for a short to voltage in the 5-volt reference circuit.
