On a 1993 Grand Cherokee lerado my VIC will not come on what should I check after the fuse?

I recently repaired my non-working 1995 ZJ VIC by reflowing the solder on the wire connections to the circuit board, and other cold solder joints. Gently move the clips that hold the plastic housing together to open it up. Mine came right back to life.

Alternately, check your local JY, and online auction sites.

Have your ignition module checked. Also check codes for bad reference signal for cam or crank sensor.

possibly dirty fuel injectors. try adding some fuel injector cleaner. best boughtin 3 packs at Walmart, etc.

What is a vic

I've been looking for the same thing, this is what i've found. Hope it's of some use.

Your VIC doesn't provide you with codes per se, it supplies other information and what you describe here is what should be written on your VIC, "Coolant Sensor Bad." The actual Coolant Sensor runs to your PCM or computer and your check engine light will come on if it runs at or above 5 volts or below 0.1 volts. If the red square on the vehicle layout is illuminated under the hood area, it means that your Coolant Recovery jug is either low on anti-freeze or the sensor next to the yellow filler cap is faulty...meaning you're low on Coolant and the VIC says that the "Coolant Sensors Bad" yet it's the amount of fluid in the plastic bottle next to the passenger side firewall, right in front of your PCM or computer. If you're low on anti-freeze, keep an eye on it, or have the coolant system pressure tested...including the 18 pound cap on the radiator itself. Also check the two wires hooked to the Coolant LEVEL Sensor in the jug with an Ohmmeter and it should be an open circuit if the level is fine, or hardly any Resistance if the level is low, causing that circuit to complete it's ground circuit and thus signaling the VIC through your BCM to turn on. (Body Control Module). The Haynes Manual you will need is # 50025 which encompasses all Jeep Grand Cherokee's from 1993 thru 2004.

Try replacing the fan relay in the fuse box under the hood.

have u check all ur gounds and fuse links around d computer

12 is a battery disconnect within the last 50 start cycles and 55 means the end of the diagnostic cycle.  Basically the computer found nothing wrong. The 12 code may seem incorrect if you haven't disconnected the battery recently, but from my experience the 12 code shows up almost all the time regardless.
