ENGINE-ECU

REMOVAL AND INSTALLATION

M1131033802258

CAUTION

• If the engine-ECU is replaced, another ECU related to KOS system should not be replaced

together. If at least two ECUs needs to be replaced, replace one ECU and then register its ID with
M.U.T.-III. Then proceed to the replacement of the other ECU.

• If the engine-ECU is replaced, perform the coding for it.
• If the engine-ECU is replaced, use M.U.T.-III to write the Chassis No. (Refer to GROUP 00 − 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

− Precau-

tions before Service, Learning Procedure for Idling in MPI Engine ).

Pre-removal and post-installation operation
• Air Cleaner Assembly Removal and Installation (Refer to

GROUP 15

− Air Cleaner ) .
