Diagnostic Procedure

STEP	INSPECTION		ACTION
1	PERFORM PCM DTC INSPECTION Perform the PCM DTC inspection using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [MZR 2.5] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZR 2.5] .)
1		No	Go to the next step.
2	INSPECT BATTERY Inspect the battery. (See BATTERY INSPECTION [MZR 2.5] .) Is there any malfunction?	Yes	Recharge or replace the battery, then go to Step 6. (See BATTERY RECHARGING [MZR 2.5] .) (See BATTERY REMOVAL/INSTALLATION [MZR 2.5] .)
2		No	Go to the next step.
3	INSPECT GENERATOR Inspect the generator. (See GENERATOR INSPECTION [MZR 2.5] .) Is there any malfunction?	Yes	Replace the generator, then go to Step 6. (See GENERATOR REMOVAL/INSTALLATION [MZR 2.5] .)
3		No	Go to the next step.
4	INSPECT INSTRUMENT CLUSTER CONNECTOR AND TERMINALS Switch the ignition to off. Disconnect the negative battery cable. Disconnect the instrument cluster connector. Inspect the connector and terminals (corrosion, damage, pin disconnection). Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 6.
4		No	Go to the next step.
5	INSPECT INSTRUMENT CLUSTER POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT AND SHORT TO GROUND Verify that the instrument cluster connector is disconnected. Reconnect the negative battery cable. Measure the voltage at the following terminals (wiring harness-side): Instrument cluster terminal U Instrument cluster terminal S Is the voltage B+ ?	Yes	Go to the next step.
5		No	Inspect the ROOM 15 A fuse and METER 10 A fuse. If the fuse is blown: Repair or replace the wiring harness for a possible short to ground. Replace the fuse. If the fuse is deteriorated: Replace the fuse. If the fuse is normal: Repair or replace the wiring harness for a possible open circuit. Go to the next step.
6	VERIFY TROUBLESHOOTING COMPLETED Make sure to reconnect all disconnected connectors. Reconnect the negative battery cable. Clear the DTC using the M-MDS. (See CLEARING DTC [INSTRUMENT CLUSTER] .) Perform the instrument cluster DTC inspection using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER] .) Is the same DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION .) Go to the next step.
6		No	Go to the next step.
7	VERIFY THAT NO OTHER DTCs ARE PRESENT Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [INSTRUMENT CLUSTER] .)
7		No	DTC troubleshooting completed.
