Expert Jeep TIPM Repair Repair & Service in Rohnert Park, CA

The TIPM (Totally Integrated Power Module) is the most notorious electrical component on 2007-2016 Jeep vehicles. It is a central relay and fuse module mounted under the hood that controls the fuel pump, wipers, horn, power windows, door locks, turn signals, headlights, and several other circuits. Chrysler consolidated all of these functions into one module to simplify wiring. The unintended consequence is that when the TIPM fails, multiple unrelated systems can stop working or behave erratically. NHTSA has received over 4,500 complaints related to TIPM failures.

The fuel pump relay is the most common and most dangerous TIPM failure. The internal relay contacts wear, corrode, or develop cold solder joints. When the relay fails open, the fuel pump does not run and the engine will not start. When it fails intermittently, the engine stalls without warning at any speed — a safety hazard that prompted NHTSA Recall 14V-302 covering 2011-2013 Grand Cherokee WK2 and 2012 Wrangler JK models. The recall fix was a TIPM replacement, but aftermarket fuel pump relay bypass kits provide a permanent fix for the fuel pump circuit specifically.

Wiper relay failures cause wipers to run at full speed with the switch off, run at the wrong intermittent speed, or not work at all. The wiper relay is internal to the TIPM and cannot be individually bypassed like the fuel pump relay — it shares timing circuits with the intermittent wiper function. Horn relay failures cause random honking, often triggered by heat. Power window relay failures cause windows to stop working or move slowly. Each of these is a separate relay circuit inside the TIPM, but all share the same printed circuit board.

The root cause is a combination of relay design, thermal cycling, and printed circuit board solder joint fatigue. The TIPM sits in the engine compartment where it experiences temperature swings from ambient to 200°F from engine heat. Internal relay contacts expand and contract with temperature, eventually creating intermittent connections. The solder joints on the relay circuit board fatigue over thousands of thermal cycles. Hot climates and vehicles that make many short trips — frequent engine on/off thermal cycles — see higher TIPM failure rates.

Repair options depend on how many circuits have failed. For a single fuel pump relay failure, a relay bypass kit is the most cost-effective permanent fix — it wires the fuel pump to a new relay mounted outside the TIPM, removing the failed circuit from the power path entirely. For multiple circuit failures — fuel pump plus wipers, or horn plus windows — the entire TIPM should be replaced. Remanufactured TIPMs with rebuilt relay circuits offer a middle ground between a bypass kit and a new unit.

TIPM replacement requires programming to the vehicle's VIN and security system. Without proper programming, the immobilizer will not recognize the new module and the vehicle will not start. We handle the programming as part of the replacement. Call (707) 584-7727 if your 2007-2016 Jeep has electrical gremlins — we can test each TIPM circuit and tell you exactly which relay has failed.
