DTC B2259


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


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.
1		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.
2		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.
3		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.
4		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.
5		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.
6		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.)
7		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.)
8		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


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.
1		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.
2		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.
3		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.)
4		No	Go to the next step.
5	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.)
5		No	DTC troubleshooting completed.
