PROCEDURE

1.

CHECK FOR DTCs (Radar Cruise2)

(a) Clear the DTCs.

Powertrain > Radar Cruise2 > 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.

Powertrain > Radar Cruise2 > Trouble Codes

Result
