DTC B1485 - BRAKE PEDAL INPUT CIRCUIT BATTERY SHORT - PINPOINT TEST REFERENCE

PINPOINT TEST 6		DTC B1485 - BRAKE PEDAL INPUT CIRCUIT BATTERY SHORT
STEP	INSPECTION		ACTION
1	CHECK CIRCUIT (BR/G) FOR VOLTAGE Key OFF. Disconnect: ABS control module connector. Key ON. Measure the voltage between ABS module circuit (BR/G), harness side and ground while applying and releasing the brake pedal. Is the voltage greater than 10 volts with the brake pedal applied and 0 volt with the brake pedal released?	Yes	Go to step 5.
1		No	Go to next step.
2	CHECK ABS MODULE BRAKE PEDAL PID Key OFF. Connect: IDS or equivalent tester. Key ON. Using the IDS or equivalent tester, monitor the ABS module brake pedal position (BPP) switch PID. Does the PID read active with the brake pedal released and read inactive with the brake pedal applied?	Yes	Go to next step.
2		No	Go to step 5.
3	CHECK THE BRAKE SHIFT INTERLOCK SOLENOID Key OFF. Disconnect: Brake shift interlock solenoid. Key ON. Using the IDS or equivalent tester, monitor the ABS module BPP switch PID. Does the PID read active with the brake pedal released?	Yes	Go to next step.
3		No	Install a new brake shift interlock. See SHIFT LOCK ACTUATOR REMOVAL / INSTALLATION . Clear the DTCs. Carry out the self-test with the brake pedal not applied.
4	CHECK CIRCUIT (BR/G) FOR A SHORT TO VOLTAGE Key OFF. Disconnect: Brake pedal position (BPP) switch connector. Key ON. Using the IDS or equivalent tester, monitor the ABS module BPP switch PID. Does the PID read active?	Yes	Repair circuit (BR/G) for a short to voltage. Clear the DTCs. Carry out the self-test with the brake pedal not applied.
4		No	Install a new BPP switch. See STOPLAMP SWITCH . Clear the DTCs. Carry out the self-test with the brake pedal not applied.
5	CHECK FOR CORRECT ABS MODULE OPERATION Disconnect all ABS connector. Check for: corrosion. pushed-out pins. spread terminals. Connect all ABS connector and make sure it is seated correctly. Operate the system and verify the concern is still present by CARRYING OUT the self-test with the brake pedal not applied. Is the concern still present?	Yes	Install a new ABS module. see ANTI-LOCK BRAKE SYSTEM (ABS) MODULE . Test the system for normal operation.
5		No	The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. Clear the DTCs. Carry out the self-test with the brake pedal not applied.
