Diagnostic Procedure

Step	Inspection		Action
1	RECORD CONFIGURATION DATA •  Switch the ignition off. •  Switch the ignition ON (engine off or on), and maintain this condition for approx. 1 min. •  Switch the ignition off, and maintain this condition for approx. 3 s. •  Switch the ignition ON (engine off or on).	—	Go to the next step.
2	VERIFY EPS CONTROL MODULE DTC •  Using the M-MDS, clear the DTC from the EPS control module. (See CLEARING DTC [ELECTRIC POWER STEERING (EPS)].) •  Using the M-MDS, perform the EPS control module DTC inspection. (See DTC INSPECTION [ELECTRIC POWER STEERING (EPS)].) •  Is the same Pending DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, go to the next step.
		No	Go to Step 5.
3	VERIFY INSTRUMENT CLUSTER DTC •  Using the M-MDS, perform the instrument cluster DTC inspection. (See DTC INSPECTION [INSTRUMENT CLUSTER].) •  Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [INSTRUMENT CLUSTER].) Repair the instrument cluster, then perform the configuration for the instrument cluster. (See INSTRUMENT CLUSTER CONFIGURATION (USING READ/WRITE FUNCTION).) (See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA).)
		No	Go to the next step.
4	VERIFY DTC TROUBLESHOOTING COMPLETED •  Using the M-MDS, clear the DTC from the EPS control module. (See CLEARING DTC [ELECTRIC POWER STEERING (EPS)].) •  Using the M-MDS, perform the EPS control module DTC inspection. (See DTC INSPECTION [ELECTRIC POWER STEERING (EPS)].) •  Is the same Pending DTC present?	Yes	Repeat the inspection from Step 1. •  If the malfunction recurs, replace the EPS control module. (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION.) Go to the next step.
		No	Go to the next step.
5	VERIFY NO DTC IS PRESENT •  Are any DTCs present?	Yes	Go to applicable DTC inspection. (See DTC TABLE [ELECTRIC POWER STEERING (EPS)].)
		No	DTC troubleshooting completed.
