Power steering malfunction indicator light illuminates/flashes even though engine has started.

TROUBLESHOOTING HINTS

•  EPS system malfunction.

―  Wiring harness malfunction

―  Connector condition malfunction

―  Torque sensor malfunction

―  Resolver sensor malfunction

Note

•  If the EPS CM detects an internal circuit malfunction in the resolver sensor, the power steering malfunction indicator light flashes.

―  EPS motor malfunction

―  Fuse malfunction

―  EPS CM malfunction

•  EPS CM detects an EPS system malfunction even though the EPS system is normal.

•  CAN communication line and/or CAN signal malfunction.

―  Vehicle speed signal error

―  Engine speed signal error

―  CAN wiring harness malfunction

•  EPS warning light circuit malfunction in the instrument cluster.

•  CAN wiring harness malfunction.

―  Malfunction in wiring harness between EPS CM and instrument cluster

•  Instrument cluster configuration procedure was not completed properly.

Diagnostic procedure

STEP	INSPECTION		ACTION
1	• Switch the ignition to off and maintain this condition approx. 1 minute. • Switch the ignition ON (engine on). • Perform the DTC inspection. (See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS.) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS.)
1		No	Go to the next step.
2	• Turn off the EPS warning light at instrument cluster using the “WL+IL” of the M-MDS active command modes function. • Does the EPS warning light turn off?	Yes	EPS CM malfunction. Replace the EPS CM. (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION.)
2		No	Perform the instrument cluster configuration, then repeat the inspection from Step 1. (See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA).) If the malfunction recurs, replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
