Inspection steps
- MIL illumination check
- Turn the ignition switch to ON.
- Check that the MIL illuminates in the combination meter assembly.RESULT
Result Go to Does not illuminate A Illuminates B B: Go to related circuit inspection listed in symptom table (Refer to SYMPTOM TABLE )
A: Go to Next Step
- Reading SSM3 data
- Connect the SSM3 to the DLC3.
- Turn the ignition switch to ON.
- Check that the communication between SSM3 and engine control computer can be executed normally.NOTE: [Current Data Display & Save] for engine can be checked.RESULT
Result Go to Communication not detected. A Communication detected. B B: Go to MIL circuit inspection (Refer to MIL CIRCUIT )
A: Go to Next Step
- Check throttle body assembly (with motor) (short-circuit inspection)
- Disconnect the connector for throttle body assembly.
- Turn the ignition switch to ON.
- Check the MIL in the combination meter assembly.RESULT
Result Go to Does not illuminate A Illuminates B B: Replacement of throttle body assembly (with motor) (Refer to REMOVAL )
A: Go to Next Step
- Check air pressure sensor assembly (short-circuit inspection)
- Disconnect the connector for air pressure sensor assembly.
- Turn the ignition switch to ON.
- Check the MIL in the combination meter assembly.RESULT
Result Go to Does not illuminate A Illuminates B B: Replacement of air pressure sensor assembly (Refer to VACUUM SENSOR assembly (FA20) )
A: Go to Next Step
- Check fuel pressure sensor (short-circuit inspection)
- Disconnect the connector for the fuel pressure sensor.
