|
|
Q.
Does trouble symptoms persist?
|
|
Replace the engine-ECU. When the engine-ECU is replaced, write the chassis number
(Refer to GROUP 00 - How to Perform Chassis Number Writing ).
After replacing the engine-ECU, register the injector identification code and learn fuel injection (Refer
to GROUP 00 - Precautions Before Service - What The Common Rail Engine Learns ).
