Diagnostic Procedure

DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	INSPECT CLOCK SPRING CONNECTOR CONDITION Switch the ignition off. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Disconnect the clock spring connector. Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. Is the connector normal?	Yes	Go to the next step.
1		No	Repair or replace the connector, then go to Step 6.
2	INSPECT Bluetooth ® UNIT CONNECTOR CONDITION Disconnect the Bluetooth ® unit connector. Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. Is the connector normal?	Yes	Go to the next step.
2		No	Repair or replace the connector, then go to Step 6.
3	INSPECT CLOCK SPRING Inspect the clock spring. (See CLOCK SPRING INSPECTION [STANDARD DEPLOYMENT CONTROL SYSTEM - MEXICO SPEC.] .) (See CLOCK SPRING INSPECTION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] .) Is the clock spring normal?	Yes	Go to the next step.
3		No	Replace the clock spring, then go to Step 6. (See CLOCK SPRING REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM - MEXICO SPEC.] .) (See CLOCK SPRING REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] .)
4	INSPECT STEERING SWITCH CIRCUIT FOR SHORT TO GROUND Verify that the clock spring and Bluetooth ® unit connectors are disconnected. Inspect for continuity between clock spring terminal 1B (wiring harness-side) and body ground. Is there continuity?	Yes	Refer to the wiring diagram and verify if there is a common connector between Bluetooth ® unit terminal F and clock spring terminal 1B. If there is a common connector: Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for short to ground to determine the malfunctioning location. Repair or replace the malfunctioning location. If there is no common connector: Repair or replace the wiring harness which is shorted to ground. Go to Step 6.
4		No	Go to the next step.
5	INSPECT STEERING SWITCH Inspect the steering switch. (See STEERING SWITCH INSPECTION .) Is the steering switch normal?	Yes	Go to the next step.
5		No	Replace the steering switch, then go to the next step. (See STEERING SWITCH REMOVAL/INSTALLATION .)
6	VERIFY THAT REPAIRS HAVE BEEN COMPLETED Always reconnect all disconnected connectors. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Clear the DTC for the Bluetooth ® unit. (See CLEARING DTC [AUDIO UNIT] .) Switch the ignition ON (engine off or on) and wait for 2 min or more. Perform the DTC inspection for the Bluetooth ® unit. (See DTC INSPECTION [AUDIO UNIT] .) Is the same DTC displayed?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the Bluetooth ® unit. (See Bluetooth® UNIT REMOVAL/INSTALLATION .) Go to the next step.
6		No	Go to the next step.
7	VERIFY IF OTHER DTCs DISPLAYED Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [AUDIO UNIT] .)
7		No	DTC troubleshooting completed.
