See step 2
- INSPECT PARKING BRAKE WIRE ASSEMBLY
*A RH *B LH *a Front view of Parking Brake Wire Assembly *b (to Wire Harness Connector) *c (to Parking Brake Actuator Assembly) - - - Remove the parking brake wire assembly.
- Check the parking brake wire assembly for damage.
OK
No damage.
HINT:
If damaged, there may be a short in the wire harness or a short to ground.
- Inspect the parking brake wire assembly.

NG
REPLACE PARKING BRAKE WIRE ASSEMBLY
Result:
OK
See step 3
- CHECK HARNESS AND CONNECTOR (PARKING BRAKE ECU ASSEMBLY - PARKING BRAKE ACTUATOR ASSEMBLY)
- Turn the ignition switch off.
- Make sure the parking brake wire assembly is securely installed.
- Disconnect the M36 parking brake ECU assembly connector.
- Disconnect the M49 or N57 parking brake actuator assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
RHTester Connection Condition Specified Condition M36-1 (MRR+) - M49-2 (RE+) Always Below 1 Ω M36-3 (MRR-) - M49-1 (RE-) Always Below 1 Ω M36-1 (MRR+) or M49-2 (RE+) - Body ground Always 10 kΩ or higher M36-3 (MRR-) or M49-1 (RE-) - Body ground Always 10 kΩ or higher LHTester Connection Condition Specified Condition M36-4 (MRL+) - N57-2 (LE+) Always Below 1 Ω M36-6 (MRL-) - N57-1 (LE-) Always Below 1 Ω M36-4 (MRL+) or N57-2 (LE+) - Body ground Always 10 kΩ or higher M36-6 (MRL-) or N57-1 (LE-) - Body ground Always 10 kΩ or higher Result
Proceed to OK NG
Result:
NG
