P/S Control Module
NOTE:
•If communication between SUZUKI scan tool and P/S control module is not possible, perform the following checks:
•*1: Turn steering wheel fully and hold it with force applied.
•*2: The voltage and current of motor decrease gradually after few seconds when steering wheel is turned.
—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.)
•For “Ignition mode” described in the following table, it means power supply mode in keyless push start system. For more details of ignition mode, refer to Description of Keyless Engine Start 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.)

•*1: Turn steering wheel fully and hold it with force applied.
•*2: The voltage and current of motor decrease gradually after few seconds when steering wheel is turned.
