4) Note installation of electrostatic protection;
Pay attention to the protection of plug pin, waterproof ring check the wiring harness side within the
connector and yellow isolation plate is intact, prevent corrosion caused by poor contact pin.
5) Fault phenomenon and judgment method
Fault phenomenon: unstable idle speed, acceleration, not starting, idle speed is too high, exhaust,
exceed the standard starting difficulty, empty
Adjustable injector control failure, failure, flameout.
Common fault: 1, due to the external device electrical overload caused by ECU may lead to the
failure of internal parts burned; 2, because ECU water and cause the circuit board corrosion etc..
Note: 1. Repair repair process do not disassemble the ECU; remove the above battery first 5
minutes, remove 2 ECU; 3, after removal of the ECU storage; 4, banned in the ECU online
connection with any line.
A simple method to measure:
1. (Connect the connector) Using engine data K line read engine fault recording;
2. (Remove connector) Checking ECU connection line is intact, focus on examination of ECU
power supply, grounding line is normal;
3. Check whether the normal work of the sensor, the output signal is credible, the line is intact;
4. Check the actuator is working properly, the circuit is intact;
5. The replacement of the ECU test.
