ENG A-STOP Control Module
NOTE:
If communication between SUZUKI scan tool and ENG A-STOP control module is not possible, perform the following checks:
•Check communication condition between PC and VCI using SUZUKI scan tool function.
•Check DLC power circuit and ground circuit.
•Check DLC cable. If necessary, check DLC cable by substituting a known-good DLC cable.
•Check CAN communication system. (“Control Module Communication Bus Off” is detected in any control module.)
•Check DLC power circuit and ground circuit.
•Check DLC cable. If necessary, check DLC cable by substituting a known-good DLC cable.
•Check CAN communication system. (“Control Module Communication Bus Off” is detected in any control module.)
