Removal and installation of the ECM

1. Before removing the ECM, read its identification data and coding. If the ECM is being removed for replacement, connect a scan tool and run the "Replace engine control unit".

2. Turn off the ignition.

3. Remove the gutter cover (see chapter 11).

4. Open the latch (see resist. illustration) and remove the ECM.



5. On models with a protective cover, bolt (3 and 4 on resist. illustrations) cuts crosswise, unscrew them with a screwdriver and remove the protective cover of the connectors (2 and 5).



6. After removing the ECM, you can disconnect its connectors.

7. Installation is carried out in the reverse order. On models with ECM protection, use new shear bolts, tighten until head is sheared. After installing a new ECM, memorize the injector codes into its memory.
