A car immobiliser is a device that isolates a cars’ engine ignition mechanism either mechanically or electronically, making it harder to start a vehicle without additional security like a transponder key present. The Verizon Connect Immobilisation feature allows you to remotely disable a vehicle through the Reveal fleet management platform.
Start by disconnecting the negative battery cable. This will disable the engine immobiliser. 2. Locate the engine control unit, or ECU. It’s usually found near the battery. 3. Using a screwdriver, remove the ECU’s cover. 4. Locate the ECU’s main fuse.The module was easy enough remove; just had to cut some wire ties and remove a ground wire they screwed into the steering column bracket. Now the part that really pisses me off: there are FOUR wire splices way the hell up under the dash at the base of the A-pillar.I the reassembled the key put 2 fresh 2016 batteries in it, and tried it on the long dead jeep and it worked, no need to reprogram the new key to the car. This obviously then allowed me to use the fob to disable the immobiliser but also the ability to have a trusty fob to lock/unlock the jeep remotely still and all for just £30 for a used ebay
SOURCE: Car won't start. If there is a blinking car icon with an "X" over it. This icon means the Immobilizer has been activated and hence won't allow the car to start. It could be due to a bad SCU, Start Control Unit. The SCU is actually the ignition switch on these cars.
