Repair completion verification 1

VERIFY THAT VEHICLE IS REPAIRED

•  Install/connect the part removed/disconnected during the troubleshooting procedure.

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Replicate the vehicle conditions at the time the DTC was detected using the following procedure.

―  Start the engine.

―  Access the following PIDs using the M-MDS:
(See PID/DATA MONITOR INSPECTION.)

•  ECT

•  TP_RELAT

•  ENG_RPM

―  Warm up the engine until the ECT PID is above 70 °C {158 °F}.

―  Perform the following:

1.  Depress the accelerator pedal to increase the engine speed to approx. 5,000 rpm.

2.  Release the accelerator pedal to decrease the engine speed to idle speed.

3.  Repeat Step 1 and Step 2 operations above 3 times in succession.
