DTC B2258 | Headlight washer relay circuit short to battery
--- | ---
DETECTION CONDITION | Open circuit or short to power supply or GND in wiring harness between PJB and headlight cleaner relay

POSSIBLE CAUSE

• Open circuit in wiring harness between PJB terminal J-02 Z and headlight cleaner relay terminal D
• Short to GND in wiring harness between PJB terminal J-02 Z and headlight cleaner relay terminal D
• Short to power supply in wiring harness between PJB terminal J-02 Z and headlight cleaner relay terminal D
• Headlight cleaner relay malfunction
• PJB malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---

1

INSPECT HEADLIGHT CLEANER RELAY CONNECTOR
• Turn the ignition switch off.
• Disconnect the headlight cleaner relay connector.
• Inspect the headlight cleaner relay connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion).
• Is there any malfunction?

Yes

Repair or replace the terminal, then go to Step 7.

No | Go to the next step.
2 | INSPECT PJB CONNECTOR • Disconnect the PJB connector. • Inspect the PJB connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 7.
No | Go to the next step.
3 | INSPECT HEADLIGHT CLEANER RELAY CONTROL CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between PJB terminal J-02 Z (wiring harness-side) and headlight cleaner relay terminal D (wiring harness-side). • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness for a possible open circuit, then go to Step 7.
4 | INSPECT HEADLIGHT CLEANER RELAY CONTROL CIRCUIT FOR SHORT TO GND • Inspect for continuity between PJB terminal J-02 Z (wiring harness-side) and body GND. • Is there continuity? | Yes | Repair or replace the wiring harness for a possible short to GND, then go to Step 7.
No | Go to the next step.
5 | INSPECT HEADLIGHT CLEANER RELAY CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between PJB terminal J-02 Z (wiring harness-side) and body GND. • Is the voltage B+? | Yes | Repair or replace the wiring harness for a possible short to power supply, then go to Step 7.
No | Go to the next step.
6 | INSPECT HEADLIGHT CLEANER RELAY • Inspect the headlight cleaner relay. (See RELAY INSPECTION.) • Is there any malfunction? | Yes | Replace the headlight cleaner relay, then go to the next step.
No | Go to the next step.
7 | VERIFY TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PJB memory using the WDS or equivalent. • Turn the ignition switch to LOCK position then ON position. • Is the same DTC present? | Yes | Replace the PJB. (See PASSENGER JUNCTION BOX (PJB) REMOVAL/INSTALLATION.)
No | DTC troubleshooting completed.
