ABS WARNING LIGHT, ASC WARNING/OPERATION LIGHT AND BRAKE WARNING light CHECK

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

Check that ABS and brake warning lights, ASC warning/operation light illuminate as follows.

NOTE: The brake warning light is used as a warning light for parking brake, brake fluid level, and EBD control.

When the ignition switch is turned to the ON position, ABS and brake warning lights, ASC warning/operation light, ASC OFF light illuminate.
The ABS and brake warning lights, ASC warning/operation light, ASC OFF light illuminate for three seconds^*1 and then turn OFF^*2 .
Otherwise, check the diagnostic trouble code.
NOTE:
- ^*1 : The ABS warning light, ASC warning/operation light, ASC OFF light may stay ON until the vehicle speed reaches 10 km/h (6.2 mph). As far as ASC-ECU stores any diagnostic trouble code related to the wheel speed sensor malfunction or the motor malfunction as past trouble, ASC-ECU continues illuminating the ABS warning light until it verifies that the malfunction for that code is resolved (startup check).
  If the steering wheel sensor or the G and yaw rate sensor system was detected to be defective during ignition switch being ON at the last time, the ASC warning/operation light and the ASC OFF light will illuminate until the vehicle speed reaches approx. 10 km/h (6.2 mph), then the steering wheel is turned to either right or left and then the ECU determines that the system is normal.
- ^*2 : The brake warning light does not turn OFF when the parking brake is applied or the brake fluid level is lowered.
