PROCEDURE
1. | CLEAR DTC |
(a) Operate the GTS to clear the codes.
Chassis > Brake > Clear DTCs(b) Press the DTC clear button.
(c) Turn the ignition switch off.
|
2. | RECONFIRM DTC |
(a) Operate the GTS to read the DTCs.
Chassis > Brake > Trouble Codes Result | Proceed to |
---|---|
Any CAN communication system relating DTCs are output | A |
None of the above conditions are met | B |
HINT:
If the CAN communication system DTC and the relevant sensor DTCs are output simultaneously, troubleshoot the relevant sensor DTCs (for VSC system) after the CAN communication system returns to normal.
