DTC B2555	Dome light output circuit short to battery
DETECTION CONDITION	Short to power supply in wiring harness between PJB and interior lights
POSSIBLE CAUSE	• Short to power supply in wiring harness between PJB terminal J-05 U and interior light terminal C • Short to power supply in wiring harness between PJB terminal J-05 U and map light terminal C • Interior light malfunction • Map light malfunction • PJB malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT INTERIOR LIGHT AND MAP LIGHT CONNECTORS • Turn the ignition switch off. • Disconnect the interior light and map light connectors. • Inspect the interior light and map light 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 INTERIOR LIGHT AND MAP LIGHT CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between PJB terminal J-05 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 5.
3		No	Go to the next step.
4	INSPECT INTERIOR LIGHT AND MAP LIGHT • Inspect the interior light and map light. (See INTERIOR LIGHT INSPECTION, MAP LIGHT INSPECTION.) • Is there any malfunction?	Yes	Replace the interior light or map light, then go to the next step. (See INTERIOR LIGHT REMOVAL/INSTALLATION, MAP LIGHT 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 M-MDS. • Perform the self-test. (See PJB SELF-TEST[PJB].) • Is the same DTC present?	Yes	Replace the PJB. (See PASSENGER JUNCTION BOX (PJB) REMOVAL/INSTALLATION.)
5		No	DTC troubleshooting completed.
