Installing engine control module (ECM)
Install in reverse order of removal.
- Thereafter, the engine control module must be equipped with the metal retainer.
- Clean threaded holes for shear bolts of locking compound residue. Cleaning can be performed with a thread cutter (tap).
- Always use new shear bolts.
NOTE:
When ending Guided Fault-Finding, the tester attempts to erase the DTC memory of all control modules. If this is not successful, the remaining DTCs stored in memory must be corrected until all DTCs can be erased.
