B3606

DTC B3606

CIRCUIT DESCRIPTION
The driver seat module (DSM) monitors the location of the adjustable pedals using the brake pedal position (BPP) sensor. The BPP 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
The system voltage must be between 9-16 volts.

CONDITIONS FOR SETTING THE DTC
The BPP 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 DSM will not store or recall electronic adjustable pedals (EAP) memory or exit position settings.

CONDITIONS FOR CLEARING THE DTC
- The DTC will be current for as long as the fault is present.
- When the fault is no longer present the DTC will be a history status code.
- The history DTC will be cleared after 100 error-free ignition cycles, or by using the scan tool clearing DTCs feature.

DIAGNOSTIC AIDS
A short to voltage on a sensor signal circuit or an open ground may effect other sensors using a common 5-volt reference and ground circuits causing the following DTCs to set:
- DTC B1825
- DTC B2435
- DTC B2440

TEST DESCRIPTION

Step 1 - Step 11:

Step 12 - Step 15:

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