Which fuse do you take out to reset your check engine light on a Chrysler Town and Country?


Instructions
    • 1

      Let the light reset itself. When the engine trouble has been fixed, a Chrysler engine resets the "Check Engine" light automatically after 40 successful runs. If it doesn't reset, the problem likely still exists.

    • 2

      Force the computer into "Successful Run" mode. Start the Chrysler and drive forward a few feet, then put it in reverse and go backward a few feet. Do this three times and shut the engine off. Crank it again to see if the light has been on.

      Disconnect the battery for several minutes. This resets everything in the vehicle, including the clock and radio settings. Reapply the radio settings and adjust the time when the battery is reconnected.

      Use a diagnostic scanner to clear the codes. Connect the scanner to the test port, also called the ALDL (Assembly Lineicon1.png Diagnostic Link) usually located under the dash (see Resources section). Turn the engine "On" and follow the prompts on the scanner to pull the engine codes. Select the option to clear them.

I replaced the alternator on my 1999 Audi A6 with 2.8 engine. Now the check engine light is on. Was not on prior to the repairn. How do I correct?



Instructions on How to Turn Off The Check Engine Light:
Step 1. If not using a scan tool, locate your vehicle's battery. Disconnect the 12v positive cable (red wire) from battery terminal (+). Leave it disconnect for 5 minutes. While the battery is disconnected, cycle the ignition switch to ON position 3 times. If using a scan tool to turn off the check engine light, follow manufacturers directions. You will need to find your vehicle's OBD II Data Link Connecter (DLC) and connect your scan tool to the DLC, then follow the steps indicated on your scan tool or scan tool manual.

Step 2. Insure ignition switch is OFF. Reconnect the battery 12v positive cable (red wire) to battery terminal (+).

Step 3. Cycle ignition switch to ON position and wait 1 minute, then start your vehicle. Check Engine Light or Service Engine Soon Light should be reset and turned OFF.

Step 4. Drive your vehicle for one week under normal driving conditions. During this period the emissions computer is gathering data and re-learning your vehicle's emissions components and systems. The emissions computer OBDII (on-board diagnostics) system must complete at least one drive cycle (in some cases two or three). A drive cycle is a sequence of internal tests which the emissions computer runs while your vehicle is being driven. This insures all emissions systems are functioning properly. Proper "readiness flags" are set as the computer completes it's cycles. Test cycles are unique to a vehicle. Certain cycles run under very strict parameters, and may require extended driving time to trigger on. Cycle data and readiness flag information is available through your dealership's service department. The data vary widely.

Will a faulty BCM prevent vehicle from starting? New fuel pump and filter. Injectors are good but owner now telling me the gauges have been wacky for couple months. Engine fan not working, fuel gauge


The car should be throwing codes. The check engine light would be on. Disconnect battery for 30 minutes, reconnect, drive, and see if there is any issue. The BCM should not be at issue here. BODY Control Module.

I have a 2004 Chevy Cavalier. A couple of months ago, just after starting the car one day, the 'check engine' and 'trac off' lights both came on. I immediately shut off the car, waited approximately 5...


Many cars have the cooling fan on a thermostat or time delay, to allow it to run for a short period of time after the engine turns off, to cool the engine off. You may have just never noticed it before. So I wouldn't worry about that.
Your real problem is the blowing fuses, apparently you have a short somewhere in your wiring. Putting in bigger and bigger fuses is a great way to set fire to your wiring harness. It's possible that the wire is pinched or chafed somewhere, and perhaps when you hit a bump just right, it touches and shorts.
You may have to take this to the Chevy dealer or a GOOD independent shop to have them chase it down. Unless someone out there knows exactly what this is, it could be a tough one to find.

How would u reset the maintaince required light after you changed the fluids?


Hi there biggryder 12!

The best way to reset the maintenence light after you have resolved the problem is to disconnect the battery.
  1. First disconnect the battery (negative terminal)
  2. Let the disconnected battery sit for at least 15 minutes
  3. After 15 minutes reconnect the negative cable
The reason to leave it disconnected for 15 minutes is to give the capasitors time to fully discharge their charge. If after doing this procedure and your light comes back on you need to check if there is any maintenence procedure that may have been missed or have the codes read.

I hope this was of assistance to you.
