1 Place the ignition switch in the RUN position.
2 Place the headlamp switch in the OFF position.
3 Fully apply the brake.

5 If the DRL does not operate, make sure the SJB is configured for DRL before proceeding to the next step.
2. Verify the brake warning indicator operation.
- Apply and release the parking brake while observing the brake warning indicator.
