- To prevent an accident, work with another person (one person drives vehicle, other person operates M-MDS).
- Comply with the legal speed limits and perform the procedure in a safe place.
- Verify the PIDs [ENG_RPM] and [FUEL_PULSE_WD] using the PID/data monitor function. (Refer to [PID/DATA MONITOR INSPECTION ] in the troubleshooting service information)
- Drive the vehicle under the condition of PID [ENG_RPM] 4, 000 rpm.
- When the accelerator pedal is released without depressing the brake pedal, verify that the PID [FUEL_PULSE_WD] indicates 0 ms until the PID [ENG_RPM] reaches approx. 1, 200 rpm and the PID [FUEL_PULSE_WD] indicates 2 to 5 ms when the PID [ENG_RPM] is approx. 1, 200 rpm or less.
- If it cannot be verified, inspect the following items and if there is a malfunction, repair or replace the malfunctioning location.
- Under load/under no-load determination signal
