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.
•  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 M-MDS.
•  Perform the self-test.
•  Is the same DTC present?
Yes
Replace the PJB.
