Installing the Engine Control Module

Install in reverse order of removal.

-- Thereafter, the engine control module must be equipped with the protective housing.

-- Clean threaded holes for shear bolts of locking compound residue. Cleaning can be performed with a thread cutter (tap).

-- Always use new shear bolts.

-- Check the DTC memory and erase if necessary. The readiness code must be generated in the engine control module if the DTC memory was erased. Use a Vehicle Diagnostic Tester to do this.

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.
