 Yes Go to the next step.
No Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.
5 PURPOSE: VERIFY CONNECTOR CONNECTIONS
  • Start the engine.
  • Access the VLV_TIMING_ACT_IN PID using the M-MDS. (See PID/DATA MONITOR INSPECTION .)
  • Does the PID value fluctuate when the following connectors are shaken?
    • Electric variable valve timing motor/driver
