DIAGNOSING SYSTEM

Description

The ECM controls the cruise control function and dynamic laser cruise control in a vehicle. Data on the cruise control system, dynamic laser cruise control system and the DTCs can be read from DLC3 in the vehicle. If the CRUISE main indicator light does not come on after the DTC check, there is a malfunction in the cruise control and dynamic laser cruise control system. Use the hand-held tester or SST check wire to check and solve the problem.
