id0903d5808200

9

Water temperature gauge indication is defective

POSSIBLE CAUSE

•  PCM malfunction

•  Instrument cluster malfunction

•  Connector or pin malfunction

•  Short circuit in wiring harness between CAN-L, CAN-H and GND

•  Open circuit in CAN wiring harness (CAN-L, CAN-H)

•  CAN wiring harness (CAN-L, CAN-H) short each other

9	Water temperature gauge indication is defective
POSSIBLE CAUSE	• PCM malfunction • Instrument cluster malfunction • Connector or pin malfunction • Short circuit in wiring harness between CAN-L, CAN-H and GND • Open circuit in CAN wiring harness (CAN-L, CAN-H) • CAN wiring harness (CAN-L, CAN-H) short each other

Diagnostic procedure

STEP	INSPECTION		ACTION
1	• Start the engine. • Does the water temperature gauge needle move to medium range gradually and stay there?	Yes	Troubleshooting completed.
1		No	Go to the next step.
2	• Do the speedometer, the tachometer, and the oil pressure gauge operate normally?	Yes	Go to the next step.
2		No	Go to Step 4.
3	• Start the instrument cluster input/output check mode. • Inspect the water temperature gauge using the check code 25. • Is the water temperature gauge normal?	Yes	Inspect the PCM or connectors.
3		No	Replace the instrument cluster.
4	• Start the engine. • Does the ABS warning light turn off?	Yes	Inspect the PCM or connectors.
4	• Start the engine. • Does the ABS warning light turn off?	No	Replace the instrument cluster.
5	• 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.
5		No	Go to Step 7.
6	• Disconnect the negative battery cable. • 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.
6		No	Replace the instrument cluster.
7	• Turn the ignition switch to LOCK position. • 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.
7		No	Repair or replace the terminal.
8	• Disconnect the negative battery cable. • Measure the resistance between the instrument cluster connector terminals 1J and 1L. • Is the resistance 114—126 ohms?	Yes	Inspect the wiring harness and CAN system-related module. Repair or replace the malfunctioning part.
8		No	Replace the instrument cluster.
