Engine Control Module (ECM) Removal and Installation: Notes
CAUTION:
As ECM consists of precision parts, be careful not to expose it to excessive shock.
NOTE:
If ECM is replaced with new one (VIN data is still not registered) or with used one (VIN data of other vehicle has been registered previously), make sure that re-register VIN data correctly by performing "VIN REGISTRATION : ".
Otherwise, MIL remains on even if the engine started or it causes the inconsistency between registered VIN data in ECM and actual VIN.
