Diagnostic procedure

STEP	INSPECTION		ACTION
1	• Start the engine. • Does the MIL turn off?	Yes	Troubleshooting completed.
1	• Start the engine. • Does the MIL turn off?	No	Go to the next step.
2	• Inspect the DTC for the PCM ON-BOARD DIAGNOSTIC SYSTEM. • Has DTC been recorded in memory?	Yes	Go to the applicable DTC troubleshooting procedure. (See DTC TABLE[MTX, LF ATX (FS5A-EL)].) (See DTC TABLE[LF ATX (FN4A-EL), L3 ATX].) (See DTC TABLE[L3 Turbo].) (See DTC TABLE[ZJ, ZY, Z6].) (See DTC TABLE[MZ-CD 1.6 (Y6)].)
2		No	Go to the next step.
3	• Start the instrument cluster input/output check mode. (See INSTRUMENT CLUSTER INPUT/OUTPUT CHECK MODE.) • Does the MIL turn off with a check code other than 26?	Yes	Go to the next step.
3		No	Replace the instrument cluster.
4	• Disconnect the negative battery cable. • Measure the resistance between the DLC-2 terminals F and E. • Is the resistance 54—66 ohms?	Yes	Go to the next step.
4		No	Go to Step 6.
5	• Inspect the DLC-2 terminals F and E for short to power supply or GND. • Is there any malfunction?	Yes	Inspect the wiring harness and CAN system-related module. Repair or replace the malfunctioning part.
5		No	Replace the instrument cluster.
6	• Turn the ignition switch 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.
6		No	Repair or replace the terminal.
7	• Disconnect the negative battery cable. • Measure the resistance between the instrument cluster connector terminals 1I and 1K. • Is the resistance 114—126 ohms?	Yes	Inspect the wiring harness and CAN system-related module. Repair or replace the malfunctioning part.
7		No	Replace the instrument cluster.
