Function Explanation (DTC Detection Outline)

• The PCM performs correction learning via the fuel injection amount and the fuel injection timing feedback control. If the condition in which the calculated correction value is the higher limit guard or more exceeds the specified period of time, the PCM determines a fuel injector malfunction and stores DTCs.

Repeatability Verification Procedure

• Start the engine and warm it up.

― Drive the vehicle on flat roads under the following conditions 4 times repeatedly.

Caution

• Observe legal speed limits when driving the vehicle and perform the procedure in a location where safety can be assured.

1. Accelerate to 15 km/h and decelerate to 0 km/h.

2. Wait for 20 s while idling.

3. Accelerate to 30 km/h, and decelerate to 0 km/h after driving the vehicle while maintaining the speed for 20 s.

4. Wait for 20 s while idling.

5. Accelerate to 50 km/h, and decelerate to 0 km/h after driving the vehicle while maintaining the speed for 20 s.

6. Wait for 20 s while idling.

• Accelerate to 70 km/h and drive the vehicle while maintaining the speed for 60 s.

• Decelerate to 50 km/h and drive the vehicle while maintaining the speed for 60 s.

• Accelerate to 70 km/h and drive the vehicle while maintaining the speed for 60 s.

• Accelerate to 100 km/h and drive the vehicle while maintaining the speed for 30 s.

• Accelerate to 120 km/h and decelerate to 0 km/h.

• Stop the engine.
