PROCEDURE
|
1. |
CUSTOMER PROBLEM ANALYSIS (CHECK CONDITION WHEN MALFUNCTION OCCURRED) AND FREEZE FRAME DATA |
(a) Interview the customer to check the vehicle conditions when the brake system warning light (yellow indicator) illuminated.
(b) Using the GTS, check for Freeze Frame Data that is recorded when a DTC is stored.

Chassis > Brake Booster > Trouble Codes
HINT:
Freeze Frame Data is only stored once when a DTC is stored.
|
|
2. |
CLEAR DTC |
(a) Clear the DTCs.
