Are you experiencing issues with your TIPM? Let’s break down what a TIPM is, how to identify if it’s causing your car problems, and what you can do about it.
What is a TIPM?
TIPM stands for “Totally Integrated Power Module,” which is a central component that manages your car’s electrical system. Think of it as a black box, made of hard plastic, containing fuses and a power board that control various electrical functions in your vehicle. While your TIPM might look a bit different from others, the basics remain the same.
How Can You Tell If Your TIPM Is the Problem?
If your car is acting up electrically, it might be due to a faulty TIPM. Here are some signs to watch out for:
- Windshield Wipers Acting Up: If your windshield wipers start on their own or don’t respond when you turn them on, it could be due to a TIPM issue.
- Car Acting Unpredictably: The car may struggle to start or not start at all. You might notice doors locking themselves, the horn or alarm going off randomly, or the blinkers turning on by themselves. These are classic signs that the TIPM is malfunctioning.
- Electrical Devices Malfunctioning: If different electrical components in your car start behaving strangely, it’s usually a red flag for a faulty TIPM. A common issue is the car not starting due to a bad fuel pump relay inside the TIPM.
Which Vehicles are Most Affected?
Vehicles from 2007 to 2015, especially Jeep, Chrysler, and Dodge models, are most commonly affected by TIPM issues. Over time, the TIPM can fail, causing a variety of electrical problems in these cars.
What to Do If You Have a Faulty TIPM
If you suspect a faulty TIPM, you have a few options:
- Visit a Dealership: This is usually the most expensive route. Dealerships may charge a premium for diagnosing and replacing the TIPM.
- Repair Your TIPM: Many services, including ours, offer TIPM repair. This involves removing the TIPM from your car, sending it in for repair, and reinstalling it once it’s fixed. While it is a cost-effective solution, keep in mind that your car will be out of commission for a few days.
- Purchase a Rebuilt TIPM: For slightly more than the cost of a repair, you can purchase a rebuilt TIPM from our website, autocomputerperformance.net. This allows you to avoid the downtime associated with repairs, and all rebuilt TIPMs come with a one-year warranty.
Common TIPM Error Codes & Troubleshooting Tips
-
U0100: Lost Communication with ECM/PCM “A”
- What it means: The TIPM can’t talk to the engine control module (ECM) or powertrain control module (PCM). This is a serious issue that can affect many systems.
- Tips:
- Check the wiring harness between the TIPM and ECM/PCM for damage or loose connections.
- Inspect the connectors at both the TIPM and ECM/PCM for corrosion.
- This could indicate a faulty TIPM or ECM/PCM, but further diagnosis is needed.
-
U0140: Lost Communication With Body Control Module
- What it means: The TIPM has lost communication with the body control module (BCM), which controls things like lights, locks, and windows.
- Tips:
- Similar to U0100, check wiring and connections between the TIPM and BCM.
- Look for signs of water damage or corrosion in the BCM.
-
U0155: Lost Communication With Instrument Panel Cluster (IPC) Control Module
- What it means: The TIPM can’t communicate with the instrument cluster, which could cause problems with gauges, warning lights, and other displays.
- Tips:
- Check the wiring and connections between the TIPM and the instrument cluster.
- Inspect the instrument cluster itself for any signs of damage.
-
U0184: Lost Communication With Radio
- What it means: The TIPM and your radio aren’t communicating. This can cause problems with the radio turning on, sound output, and controlling the radio.
- Tips:
- Check the radio’s fuse in the TIPM’s fuse box.
- Inspect the wiring harness between the TIPM and the radio.
-
P068A (or similar “P” codes related to relays): These codes usually indicate a problem with a specific relay within the TIPM.
- Tips:
- Identify the relay associated with the code (your owner’s manual or online resources can help).
- Check the condition of the relay; it may need to be replaced.
- If replacing the relay doesn’t help, there might be a problem with the TIPM’s internal circuitry controlling that relay.
- Tips:
General TIPM Code Tips
- Check for Technical Service Bulletins (TSBs): Manufacturers sometimes issue TSBs for known TIPM problems. Check your vehicle manufacturer’s website or contact a dealer to see if any TSBs apply to your vehicle and the codes you’re experiencing.
- Intermittent problems: If your TIPM issues come and go, it can be harder to diagnose. Keep a record of when the problems occur and any related conditions (e.g., temperature, weather). This might help you or a mechanic identify a pattern.
Important Reminder: Always disconnect the negative battery cable before working on any electrical components in your vehicle, including the TIPM.
