Solutions To Other Dodge/Jeep/Chrysler/VW Problems
Lights, Dashboard, Warning Lights, Won't Turn Over, and Other Intermittent TIPM Issues
Many people report situations where their vehicle "goes nuts" with headlights, fans, horn, gauges, wipers, door locks, or other items turn on/off on their own. We do not have a proven solution for these type of intermittent problems, but will offer you some suggestions based on our own research and feedback from others. Certain relay-driven items (horn, door locks, wipers, fuel pump, etc) that fail to work all the time may be able to be repaired. If you are able to fix your problem, please contact us and share your solution so we can share with others. The following suggestions are the result of thousands of phone calls and emails since 2014:
- Open TIPM lid
- Check all mini blade and cartridge fuses to make sure none are blown
- Swap all similar grey relays with the same part numbers. These grey relays are removable and located next to your fuses. Move A to B, B to C, C to D, and D to A. Orientation isn't critical on rectangular relays, so you can rotate the relay 180 degrees if needed. If you notice a new problem and/or the old problem is fixed, you may have a relay issue. Replace affected relay. Or you can test each relay with a 9V battery and multimeter.
- Reseat all connectors on the bottom of the TIPM. This will take up to 30 minutes. You may have a bad connection between pins.
- MANY people have reported success with tightening of all ground connections and cleaning the pins on the electrical connectors under the TIPM. Tighten all bolts/screws that contain a wire leading directly into the chassis (frame) of the vehicle. These connections are often located near the TIPM. Ground connections can become rusted, corroded, or loose. Many electrical functions in the TIPM turn on/off by switching ground connections.
- Remove the (+) battery connection on upper left of TIPM or the (-) battery connection on vehicle battery. Reinstall connection. This resets the TIPM. Then turn vehicle on and go to RUN position, but don't start. Wait 12 secs, then turn off, then start normally.
- Replace TIPM to see if the problem persists. We have used TIPMs for sale starting at $350 with a one year warranty.
- You may have a faulty Front Control Module (FCM) or Body Control Module (BCM). The BCM is an electronic control unit responsible for monitoring and controlling various electronic accessories in a vehicle's body. Typically in a car the BCM controls the power windows, power mirrors, air conditioning, immobilizer system, central locking, etc. The FCM is a micro controller based module that mates to the power distribution center to form the Integrated Power Module (IPM). The FCM controls power to some vehicle systems electrical and electromechanical loads based on inputs received from hard wired switch inputs and data received on the CAN bus circuit.
SOLVED - Lights, dashboard, and windshield wipers going crazy on a 2008 Chrysler Town & Country Touring Van
A customer reported in September 2016 that buying a new TIPM did not solve his problem, and the dealer eventually found corrosion on the pigtail wiring on the driver side sliding door. Cost was $209 for the part and $180 in labor. The customer wanted me to tell everyone to check all wiring for corrosion before taking a van to have the TIPM replaced. The dealer identified the problem part as FP number: 68043333-AB with description: Wiring SL 0801502. See photos below.
Starter Won't Engage
PROBLEM - If you try to start your car, but it intermittently won't even try to power the starter and turn the flywheel, you may have a loose shift cable. The shift cable connects your shift lever to the transmission.
POSSIBLE SOLUTION - This cable sometimes stretches or becomes loose and sensors think the vehicle is not in park. On some Dodge Caravans, you simply need to remove the battery and battery box under the hood to access this cable and adjust it accordingly.
Starter Stops After 2 Seconds
PROBLEM - My issue has only been with starting the 2011 Dodge Grand Caravan...it "tics" as if battery is dead randomly, but eventually starts. I do NOT hear the fuel pump continue to run after vehicle is off. Could this still be the fuel pump relay? If so...could a novice use your bypass cable in order to make sure before contacting you for permanent repair? I was quoted $1100 for replacement of my TIPM, and am not a happy camper that this was not covered under my pricey warranty.
POSSIBLE SOLUTION - Whatever you do, don't spend $1100 on a new TIPM. You can buy used TIPMs for much less here. To address your issue, a ticking battery usually indicates low voltage being supplied to the starter. Corroded or inadequately tightened battery terminals can cause the vehicle to not start in certain situations. The connection may provide just enough current to permit accessory power, but no starting. I would clean your battery terminals. You could also have a bad/corroded ground connection that is causing intermittent issues with your TIPM. As for the problem being a fuel pump relay, it's possible. Bad fuel pump relays won't cause any tics, but will instead make the vehicle act like it's out of gas. Of course, a "stuck on" fuel pump relay will drain your battery - causing some of the initial issues you describe with tics. If I were you, I would look into my ground connections to the chassis and check for corroded wiring. If you do buy a bypass cable, it's worth noting that any novice can use it. We include simple directions with photos of how to connect it.
