A Guide To Installing Your Engine Computer Module (ECM)
All our units are 100% tested, programmed with the latest software available to your vehicle, fully remanufactured & ready to plug and play!!!
The ECM (electronic control module) in a car is the vehicle's brain. The ECM is responsible for receiving and transmitting signals to all the sensors in the vehicle. When the ECM goes bad, it can cause the car to run erratically, if at all.
The ECU Installation is simple & takes about 30 minutes to complete. These instructions are meant to be a generic guide to try fit most cars.
Before reconnecting the ECM make sure that:
- Battery is charged over 12v
- Wiring harness is clean and in good condition
- Any known defective parts have been replaced
- All ground connections are in good condition and are tightly secured
- Disconnect battery from the car, wait 15 minutes before installing new ECM
- Locate the ECM either in the engine compartment or under one of the front seats in the vehicle. (consult your owner’s manual)
- Unbolt the screws holding the ECM in place (Tool: Socket Wrench)
- Pull the old ECM out and replace it with the new one.
- Bolt the new ECM in place. (ensure the bolts are tight.)
- Reconnect the electrical wires and the battery.
- Start your vehicle to verify all the functions are working.
- Check engine light is off
- Car revs up smoothly
- No smoke from exhaust
- Car idles well
Note: Vehicles that have a Security System ( Immobilizer System ) will still need to be reprogrammed by a locksmith, dealer or licensed mechanic with programming tools. (Cars usually dated 2000 and up have security system).
