Diagnostic Procedure

STEP	INSPECTION		ACTION
1	Start the engine. Does the malfunction warning light turn off?	Yes	Troubleshooting completed. (The system is normal.)
1		No	Go to the next step.
2	Retrieve DTC from the PCM using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [MZR 2.5] .) Is the DTC P0571:00 and/or P0703:00 present?	Yes	Go to applicable DTC inspection. (See DTC P0571:00 [MZR 2.5] .) (See DTC P0703:00 [MZR 2.5] .)
2		No	Go to the next step.
3	Start the engine. Verify that the warning and indicator lights condition. Do two or more lights illuminate at the same time?	Yes	Go to the Step 5.
3		No	Go to the next step.
4	Turn off the malfunction warning light using M-MDS instrument cluster active command modes WL+IL. (See ACTIVE COMMAND MODES TABLE [INSTRUMENT CLUSTER] .) Does the malfunction warning light turn off according to active command modes?	Yes	Inspect the connector condition of the following parts: Instrument cluster PCM If connector connection is poor: Connect the connector of each part securely. If malfunction occurs on part side: Replace each part. If malfunction occurs on vehicle wiring harness side: Repair or replace the pins or connector.
4		No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION .)
5	Retrieve DTC from the instrument cluster using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER] .) Is the DTC detected?	Yes	Go to the applicable DTC troubleshooting procedure. (See DTC TABLE [INSTRUMENT CLUSTER] .)
5		No	Go to the next step.
6	Disconnect the negative battery cable. Measure the resistance between the DLC-2 terminals F and E. Is the resistance below 60 ohms ?	Yes	Go to the next step.
6		No	Go to Step 9.
7	Disconnect the negative battery cable. Inspect the DLC-2 terminals F and E for short to power supply or ground. Is there any malfunction?	Yes	Inspect the wiring harness and CAN system-related module. Repair or replace the malfunctioning part.
7		No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION .)
8	Switch the ignition to off. Inspect the instrument cluster connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion). Are the terminals normal?	Yes	Go to the next step.
8		No	Repair or replace the terminal.
9	Disconnect the negative battery cable. Measure the resistance between the instrument cluster connector terminals 2X and 2W. Is the resistance 114-126 ohms ?	Yes	Inspect the wiring harness and CAN system-related module. Repair or replace the malfunctioning part.
9		No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION .)
