Trouble Starting Your Jaguar? It Could Be the ECM

Difficulty starting a car could be due to any number of problems. One possible reason your Jaguar won't start is that its electronic control unit (ECU) has been damaged. If this is the case, Jaguar computer exchange or Jaguar ECU replacement can address the problem and save you money over taking your car back to the dealer. At Specialized ECU Repair, we exchange and repair ECUs from many European cars, including Jaguars.

Finding and Removing Your ECU

If you are interested in having your Jaguar ECU tested, repaired, or exchanged, you first have to remove the ECU on your car. Look for your ECU under a black, plastic cover at the rear of the left side of the engine bay. It is held in by security screws, which you'll have to remove to gain access to the ECU. When sending it in for Jaguar ECU replacement, package it securely with bubble wrap to prevent damage during shipping.

The First Step Is ECU Testing

If you're only interested in finding out whether the ECU is causing your problem, you can elect to have it tested. If the ECU is not faulty, it can be returned to you. If you're in a hurry to get your car running again, you can ask for a Jaguar computer exchange, where your ECU is swapped for one that has been refurbished and thoroughly tested.

Installing a Repaired ECU

If you're uncomfortable with any aspect of ECU reinstallation, have an ASE Certified technician install it for you. Before reinstalling the ECU, ensure the battery is charged over 12V, and the wiring harness and all ground connections are in good condition and secured. Disconnect the negative side of the battery, connect the ECU, and reconnect the negative side of the battery.

Choose an ECU Service That Offers a Warranty

Always choose an ECU repair or exchange service that offers a warranty and that thoroughly tests your repaired ECU before shipping it to you. At Specialized ECU Repair, we proudly offer a five year warranty on ECUs that we repair and on exchange ECUs. Keep your sales invoice and warranty form should your ECU give you trouble under warranty.
