• External circuit is normal

Test Procedure 

• Procedure
• 1. -

     Do the HDS [F-CAN Bus Connected Unit Check].

• Normal Conditions
• 1. -

     The HDS indicates body control module is Detected on BF-CAN.

Results 

• If it is abnormal, there is a problem with the body control module.

VSA modulator-control unit Inspection
