DTC B2259 | Front wiper variable intermittent switch circuit failure Intermittent wiper circuit short to ground
--- | ---
DETECTION CONDITION | • Input voltage from the windshield wiper and washer switch (INT volume or sensitivity adjustment volume) is excessively low or high • Short to GND in wiring harness between PJB and windshield wiper and washer switch (INT)

POSSIBLE CAUSE

• Open circuit in wiring harness between PJB terminal J-04 U and windshield wiper and washer switch terminal G
• Short to power supply in wiring harness between PJB terminal J-04 U and windshield wiper and washer switch terminal G
• Short to GND in wiring harness between PJB terminal J-04 U and windshield wiper and washer switch terminal G
• Short to GND in wiring harness between PJB terminal J-04 E and windshield wiper and washer switch terminal D
• Windshield wiper and washer switch malfunction
• PJB malfunction

Diagnostic procedure

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

1

INSPECT WINDSHIELD WIPER AND WASHER SWITCH CONNECTOR
• Turn the ignition switch off.
• Disconnect the windshield wiper and washer switch connector.
• Inspect the windshield wiper and washer switch 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 8.

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 8.
No | Go to the next step.
3 | INSPECT WINDSHIELD WIPER AND WASHER SWITCH CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between PJB terminal J-04 U (wiring harness-side) and windshield wiper and washer switch terminal G (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 8.
4 | INSPECT WINDSHIELD WIPER AND WASHER SWITCH CIRCUIT FOR SHORT TO GND • Inspect for continuity between PJB terminal J-04 U (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 8.
No | Go to the next step.
5 | INSPECT WINDSHIELD WIPER AND WASHER SWITCH CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between PJB terminal J-04 U (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 8.
No | Go to the next step.
6 | INSPECT WINDSHIELD WIPER AND WASHER SWITCH CIRCUIT FOR SHORT TO GND • Inspect for continuity between PJB terminal J-04 E (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 8.
No | Go to the next step.
7 | INSPECT WINDSHIELD WIPER AND WASHER SWITCH • Inspect the windshield wiper and washer switch. (See WINDSHIELD WIPER AND WASHER SWITCH INSPECTION.) • Is there any malfunction? | Yes | Replace the windshield wiper and washer switch, then go to the next step. (See WIPER AND WASHER SWITCH REMOVAL/INSTALLATION.)
No | Go to the next step.

8

VERIFY TROUBLESHOOTING COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PJB memory using the WDS or equivalent.
• Perform the self-test.
(See PJB SELF-TEST.)
• Is the same DTC present?

Yes

Replace the PJB.
(See PASSENGER JUNCTION BOX (PJB) REMOVAL/INSTALLATION.)

No | DTC troubleshooting completed.

DTC B2259 | Trunk lid lock/unlock switch circuit failure
--- | ---
DETECTION CONDITION | Short to GND in wiring harness between PJB and trunk lid key cylinder switch
POSSIBLE CAUSE | • Short to GND in wiring harness between PJB terminal J-06 P and trunk lid key cylinder switch terminal C • Trunk lid key cylinder switch malfunction • PJB malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT TRUNK LID KEY CYLINDER SWITCH CONNECTOR • Disconnect the trunk lid key cylinder switch connector. • Inspect the trunk lid key cylinder switch 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 5.
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 5.
No | Go to the next step.
3 | INSPECT TRUNK LID KEY CYLINDER SWITCH SIGNAL CIRCUIT FOR SHORT TO GND • Inspect for continuity between PJB terminal J-06 P (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 5.
No | Go to the next step.
4 | INSPECT TRUNK LID KEY CYLINDER SWITCH • Inspect the trunk lid key cylinder switch. (See TRUNK LID KEY CYLINDER SWITCH INSPECTION.) • Is there any malfunction? | Yes | Replace the trunk lid key cylinder switch, then go to the next step. (See TRUNK LID KEY CYLINDER REMOVAL/INSTALLATION.)
No | Go to the next step.
