Diagnostic Procedure

STEP	INSPECTION		ACTION
1	Start the engine. Does the MIL turn off?	Yes	Troubleshooting completed. (The system is normal.)
1	Start the engine. Does the MIL turn off?	No	Go to the next step.
2	Start the engine. Inspect the condition of the warning lights and indicator lights. Do two or more lights illuminate at the same time.	Yes	Go to Step 5.
2		No	Go to the next step.
3	Retrieve the DTC related to the PCM using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [MZR 2.5] .) (See ON-BOARD DIAGNOSTIC TEST [MZI 3.7 V6] .) Is there any DTC retrieved?	Yes	Go to applicable troubleshooting procedure. (See DTC TABLE [MZR 2.5] .) (See DTC TABLE [MZI 3.7 V6] .)
3		No	Go to the next step.
4	Turn off the MIL using the M-MDS instrument cluster active command modes WL+IL. (See ACTIVE COMMAND MODES TABLE [INSTRUMENT CLUSTER] .) Does the MIL turn off according to the active command modes?	Yes	Verify that the PCM connector is connected securely. If the PCM connector is poorly connection: Connect the PCM connector securely. If a malfunction is in the PCM connector: Replace the PCM. (See PCM REMOVAL/INSTALLATION [MZR 2.5] .) (See PCM REMOVAL/INSTALLATION [MZI 3.7 V6] .) If a malfunction is in the vehicle side connector: Repair or replace the malfunctioning part.
4		No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION .)
5	Retrieve the DTC related to the instrument cluster using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER] .) Is there any DTC retrieved?	Yes	Go to applicable DTC inspection. (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 there resistance below 60 ohms ?	Yes	Go to next step.
6		No	Go to step 8.
7	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.
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 resistance 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 .)
