Information

Repair service of customers own unit

This is a test and repair service of the customers own unit.
The customer must send ECM, key and CAS (immobiliser) for testing / repairs
The Engine ECM is mounted in a sealed ECM-Box (plastic Box) near the firewall, below the windscreen on the passenger side of the engine bay.
The CAS is located next to the steering column
These units are often water damaged and unrepairable.
Injectronics can supply replacement units and program to suit your vehicle and CAS (immobiliser) providing you send the original ECM, key and CAS (immobiliser).
This unit requires specific programming by Injectronics
Exchange units are not user programmable
Upon refitting your repaired or Exchange Engine Module (ECM) it is imperative that you rectify the reason for the water ingress.
When there is a build-up of leaves and foreign matter at the bottom of the windscreen on the passenger side ,the drain will become blocked.
When the vehicle is washed, or it rains, water will then run down the windscreen and overflow into the ECM-Box. Eventually the Engine ECM will fail.
This Drain must be completely cleared and tested for operation.
The ECM-box (E-BOX) drain also needs to be checked for blockage.
