Description | Parking brake switch circuit malfunction
--- | ---
Detection condition | • Open circuit in parking brake switch circuit with the parking brake lever pulled (parking brake switch on).
Possible cause | • Parking brake switch connector or terminal malfunction • Parking brake switch malfunction • BCM connector or terminal malfunction • Open circuit in wiring harness between parking brake switch terminal A and BCM terminal 1K • BCM malfunction

Diagnostic procedure

Step | Inspection | Action
--- | --- | ---
1 | INSPECT PARKING BRAKE SWITCH CONNECTOR • Turn the ignition switch to the OFF position. • Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZI-3.7].) • Disconnect the parking brake switch connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is there any malfunction? | Yes | Repair or replace the connector, then go to Step 5.
No | Go to the next step.
2 | INSPECT PARKING BRAKE SWITCH • Inspect the parking brake switch. (See PARKING BRAKE SWITCH INSPECTION.) • Is there any malfunction? | Yes | Replace the parking brake lever, then go to Step 5. (See PARKING BRAKE REMOVAL/INSTALLATION [2WD (L.H.D.)].) (See PARKING BRAKE REMOVAL/INSTALLATION [2WD (R.H.D.)].) (See PARKING BRAKE REMOVAL/INSTALLATION [4WD (L.H.D.)].) (See PARKING BRAKE REMOVAL/INSTALLATION [4WD (R.H.D.)].)
No | Go to the next step.
3 | INSPECT BCM CONNECTOR • Disconnect the BCM connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is there any malfunction? | Yes | Repair or replace the connector, then go to Step 5.
No | Go to the next step.
4 | INSPECT FOR OPEN CIRCUIT IN PARKING BRAKE SWITCH CIRCUIT • Verify that the parking brake switch and BCM connectors are disconnected. • Inspect for continuity between parking brake switch terminal A (wiring harness-side) and BCM terminal 1K (wiring harness-side). • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness which has an open circuit, then go to the next step.
5 | VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Reconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZI-3.7].) • Clear the DTC for the BCM using the M-MDS. (See CLEARING DTC [BCM].) • Retrieve the BCM DTCs using the M-MDS. (See DTC INSPECTION [BCM].) • Is the same DTC displayed? | Yes | Repeat the inspection from Step 1. • If the malfunction recurs, replace the BCM. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.) Go to the next step.
No | Go to the next step.
6 | VERIFY IF OTHER DTCs DISPLAYED • Are any other DTCs displayed? | Yes | Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [BCM].)
No | DTC troubleshooting completed.
