How to Troubleshoot the Electric Servo Brake System: Self-Diagnosis

WARNING: This page is about a different variant/trim than selected.

Self-diagnosis can be classified into two categories:
- -
  Initial diagnosis: Done right after the vehicle to the ON mode and until the brake system indicator (red), and brake system indicator (amber) go off.
- -
  Regular diagnosis: Done right after the initial diagnosis until turning the vehicle to the OFF (LOCK) mode.

The electric servo brake control unit does the following functions when a problem is detected by self-diagnosis:
- -
  Switches to the non servo mode.
- -
  Turns on the brake system indicator (amber) and brake system indicator (red) depending on the failure.
- -
  Stores the DTC.
- -
  Stops the regenerative control cooperation.
