TIPM stands for Totally Integrated Power Module. On certain Chrysler-family vehicles, it combines electrical power distribution (fuses and relays) with some body-control functions. A TIPM or internal-relay fault can interrupt certain vehicle circuits, but batteries, wiring, fuses, switches and other modules can produce similar symptoms.
Start with the basics: what a TIPM is, what it controls, and how it differs from an ECU.
What does a TIPM do?
Depending on model and generation, the TIPM routes protected electrical power and may directly control circuits such as exterior lighting, wipers, horn and door locks. Some TIPM-7 versions also integrate the fuel-pump relay. It is not the same component as the engine ECU; it communicates with other controllers through the vehicle electrical network.
Symptoms drivers associate with TIPM faults
| Symptom | Potential TIPM-related explanation | Important alternatives |
|---|---|---|
| Engine cranks but will not start | On specific vehicles, an internal fuel-pump relay may fail to power the pump. | Battery voltage, crank sensor, fuel pump, immobilizer, wiring or other engine faults. |
| Engine unexpectedly stalls | A fuel-pump relay defect was documented in certain Jeep/Dodge vehicles. | Many fuel, ignition, charging and sensor faults can also cause stalling. |
| Intermittent wipers, lights, horn or locks | Circuits controlled by the TIPM can behave abnormally when the relevant control/output fails. | Local switches, motors, wiring, grounds, connectors or another control module. |
| Repeated electrical failure or fuse-related issue | Power-distribution problems, damaged terminals or water intrusion may affect a module. | External short circuits or loads can cause the fault without TIPM failure. |
If the engine stalls during driving or electrical faults affect lights or visibility, stop in a safe place and arrange qualified assistance. Do not continue driving a vehicle with unpredictable power or control functions.
Which Jeep and Dodge vehicles had a documented fuel-pump relay recall?
In the United States, official recall campaigns addressed an internal TIPM-7 fuel-pump relay on specified 2011–2013 Jeep Grand Cherokee and Dodge Durango vehicles. Early campaigns included NHTSA 14V530 (P54) and 15V115 (R09); a later recall 19V813 (V62) covered certain previously recalled vehicles. Manufacturer documents describe stalling risk and a remedy involving the fuel-pump relay and wiring.
This does not mean every 2011–2013 Grand Cherokee or Durango is affected. A recall's applicability depends on the vehicle's VIN, build details and previous repair status. For US vehicles, use the official NHTSA VIN recall lookup and contact the manufacturer if anything is unclear. Vehicles sold outside the US should use the local manufacturer/dealer recall system instead.
How is a suspected TIPM failure diagnosed?
- Identify the exact vehicle and symptom. Note make, model, model year, market, VIN and which electrical functions are affected.
- Review recalls and manufacturer service information. Determine whether a vehicle-specific program applies before paying for a part.
- Check basic power supply. A qualified technician verifies battery condition, charging voltage, fuse protection, grounds, connections and wiring according to the service manual.
- Read relevant diagnostic codes. Network and body control codes may be needed, not only basic engine OBD. Learn why DTCs alone are not a diagnosis.
- Confirm circuit-level evidence. Depending on the symptom, verify whether a commanded output and its downstream wiring operate correctly before condemning the TIPM.
Do not bypass the fuel-pump relay, bridge terminals, install oversized fuses or probe safety-system circuits based on a generic internet diagram. The correct procedure is VIN-specific and may involve high-current circuits or airbag wiring.
Does a TIPM failure require replacing the entire module?
Not always. The right remedy might be a recall repair, connector/wiring repair, an approved external-relay remedy for a particular campaign, or replacement of the relevant module. Some units require programming or configuration. Avoid blanket claims that every vehicle needs a new TIPM or that a universal bypass is safe.
TIPM vs ECU vs fuse box
| Component | Typical role |
|---|---|
| Fuse box / power distribution center | Routes and protects electrical power; exact design varies. |
| TIPM | Integrated distribution plus certain control/communication functions on specified vehicles. |
| Engine ECU / PCM | Controls engine operation and emissions; interacts with other vehicle modules. |

Common questions
What does TIPM stand for?
Totally Integrated Power Module, an integrated electrical power distribution and control module used in certain Chrysler-family vehicle designs.
Can a bad TIPM prevent a car from starting?
It can in certain systems, such as a vehicle with a failed internal fuel-pump relay, but a no-start symptom alone does not establish that the TIPM is defective.
Are all Jeep, Dodge or Chrysler vehicles affected by a TIPM recall?
No. TIPM design and recalls differ by model, year, build date and VIN. Check the manufacturer or official recall system for the specific vehicle.
Can I replace a TIPM without diagnosis?
Replacing the module without verifying power, grounds, circuits, error codes and applicable recalls risks an unnecessary and expensive repair. Some replacements also require programming.
