DRL operate with engine running and following switches are off: Headlight switch Turn signal switch (Selected turn signal light flashes, other light remains illumi- nated) Hazard warning switch Parking brake switch (Parking brake released) Step 1 1. Position the vehicle on a flat surface and block the wheels to prevent vehicle movement. 2. Turn the ignition switch to ON. 3. Measure the voltage at the following terminal wires of the DRL control unit. 4. If correct, replace the DRL control unit. B+: Battery positive voltage Step 2 1.

Before installation of the steering wheel reset the clock spring connector as follows: (1) Set the front wheels straight ahead. (2) Turn the clock spring connector clockwise until it stops. (3) Return 2.75 turns. (4) Align the marks (counterclockwise) on the clock spring connector and the outer housing. 4. Install the steering wheel and the air bag module. Verify that the air bag system is operating normally by monitor- ing the air bag warning light. Gartner Banana
