Fig. 42: Checking For Continuity Between The VSA Control Unit 47P Connector & Yaw Rate-
Lateral Acceleration Sensor 5P Connector
14. Check for continuity between the VSA control unit 47P connector terminal No. 34 and yaw rate-lateral
acceleration sensor 5P connector terminal No. 3.
Is there continuity?
YES: Go to step 15.
