REMOVAL AND INSTALLATION


caution
  • Do not replace the engine-ECU and the ETACS-ECU (immobilizer) simultaneously. Always replace the ECU by ones when the multiple ECU is replaced, and then replace the next ECU after registering the necessary IDs.
  • When the engine-ECU is replaced, coding must be performed.
  • When the engine-ECU is replaced, using M.U.T.-III to write the chassis number. (Refer to GROUP 00, Precautions before Service - How to Perform Chassis Number Writing .)
  • After the engine-ECU replacement, idling speed may be unstable because the MPI engine learning is not completed. To make it stable, let the system learn the idling (Refer to GROUP 00 - Precautions before Service, Learning Procedure for Idling in MPI Engine ).
