DTC B2212

Panel light control circuit failure

DETECTION CONDITION
Input voltage from the panel light control switch is excessively low or high
POSSIBLE CAUSE
•  Open circuit in wiring harness between PJB terminal J-03 AJ and panel light control switch terminal H
•  Short to power supply in wiring harness between PJB terminal J-03 AJ and panel light control switch terminal H
•  Short to GND in wiring harness between PJB terminal J-03 AJ and panel light control switch terminal H
•  Panel light control switch malfunction
•  PJB malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
INSPECT PANEL LIGHT CONTROL SWITCH CONNECTOR
•  Turn the ignition switch off.
•  Disconnect the panel light control switch connector.
•  Inspect the panel light control 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 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 PANEL LIGHT CONTROL SWITCH CIRCUIT FOR OPEN CIRCUIT
•  Inspect for continuity between PJB terminal J-03 AJ (wiring harness-side) and panel light control switch terminal H (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 PANEL LIGHT CONTROL SWITCH CIRCUIT FOR SHORT TO GND
•  Inspect for continuity between PJB terminal J-03 AJ (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 PANEL LIGHT CONTROL SWITCH CIRCUIT FOR SHORT TO POWER SUPPLY
•  Turn the ignition switch to the ON position (Engine off).
•  Measure the voltage between PJB terminal J-03 AJ (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 PANEL LIGHT CONTROL SWITCH
•  Inspect the panel light control switch.
•  Is there any malfunction?
Yes
Replace the panel light control switch, 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 M-MDS.
•  Perform the self-test.
•  Is the same DTC present?
Yes
Replace the PJB.
No
DTC troubleshooting completed.
