PROCEDURE

1.

CHECK FOR DTCs

(a) Clear the DTCs.

Chassis > Lane Control > Clear DTCs

(b) Reproduce the vehicle conditions that were present when the DTCs that were noted were stored.

HINT:

If the detection conditions are not met, the system cannot detect malfunctions.

(c) Check for DTCs.

Chassis > Lane Control > Trouble Codes

Result
