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. (See PANEL LIGHT CONTROL SWITCH INSPECTION.) • Is there any malfunction? | Yes | Replace the panel light control switch, then go to the next step. (See PANEL LIGHT CONTROL SWITCH REMOVAL/INSTALLATION.)
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.
• 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.
