1. |
CHECK FOR DTCs |
(a) Clear the DTCs.
Chassis > Lane Control > Clear DTCs
(b) Make sure that the DTC detection conditions are met.
HINT:
If the detection conditions are not met, the system cannot detect the malfunction.
(c) Check for DTCs.
Chassis > Lane Control > Trouble Codes
OK:
DTCs are not output.
