Engine Control Module (ECM) Removal And Installation: Notes

WARNING: This page is about a different car, the 2008 Suzuki Grand Vitara, 2007 Suzuki Grand Vitara, and 2006 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.

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.
For vehicle equipped with immobilizer control system:
If ECM is replaced with new one or with another one, make sure to register immobilizer transponder code to ECM correctly according to PROCEDURE AFTER ECM REPLACEMENT .
