DIAGNOSIS SYSTEM





1. DIAGNOSIS FUNCTION
On the combination meter, the BRAKE warning light (Red), BRAKE warning light ((Yellow) Brake control warning light), ABS warning light or VSC warning light come on to inform the driver if trouble occurs in the skid control ECU input signal or actuator system. If there is trouble in the oil pressure source (pump motor, accumulator) or the vehicle power supply is insufficient, the skid control buzzer sounds to warn the driver.






2. DIAGNOSIS DISPLAY FUNCTION
DTCs detected by the ECU can be read by connecting Techstream and performing the read command. The DTC has a detailed code that can be checked on the Freeze Frame Data screen.
3. BRAKE SYSTEM DISPLAY INITIAL CHECK
Turn the power switch ON (READY) and check that the ABS warning light, VSC warning light, brake control warning light, BRAKE warning light and SLIP indicator light come on, and then go off after approximately 3 seconds.
If any of the lights do not come on, check the bulb and the multiplex communication diagnosis.
