Substitute a known-good yaw rate-lateral acceleration sensor. If the HDS communicate with the ECM, replace the original yaw rate-lateral acceleration sensor. ■
NO -
Go to Step 28 .
  1. Disconnect the VSA modulator-control unit 46P connector, and the yaw rate-lateral acceleration sensor 4P connector.
