NO. 11 MALFUNCTION WARNING LIGHT ILLUMINATES [INSTRUMENT CLUSTER]

id0903d5007800

11 | Malfunction warning light illuminates
--- | ---
POSSIBLE CAUSE | • PCM malfunction • Instrument cluster malfunction • Connector or pin malfunction • Short circuit in wiring harness between CAN-L, CAN-H and ground • Open circuit in CAN wiring harness (CAN-L, CAN-H) • CAN wiring harness (CAN-L, CAN-H) short each other • Malfunction brake switch signal input to PCM (PCM stores DTC P0571 and/or P0703.)

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | • Start the engine. • Does the malfunction warning light turn off? | Yes | Troubleshooting completed. (The system is normal.)
No | Go to the next step.
2 | • Retrieve DTC from the PCM using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [L8, LF].) • Is the DTC P0571 and/or P0703 present? | Yes | Go to applicable DTC inspection. (See DTC P0571 [L8, LF].) (See DTC P0703 [L8, LF].)
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.
No | Go to the next step.
4 | • Start the instrument cluster input/output check mode. (See INSTRUMENT CLUSTER INPUT/OUTPUT CHECK MODE.) • Does the malfunction warning light turn off with a check code other than 26? | Yes | Inspect the PCM.
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].)
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.
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.
No | Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
8 | • 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.
No | Repair or replace the terminal.
9 | • 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.
| No | Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
