The TIPM module controls a lot of your Jeep Grand Cherokee’s functionality. If it goes bad, it can render it inoperable, usually due to an issue with getting fuel.
What is a TIPM?
TIPM stands for Totally Integrated Power Module. Think of it like the motherboard that houses all of the important fuses and power relays on your Grand Cherokee. The TIPM is only found in Chrysler made vehicles (including the Volkswagen Routan). It’s a fuse box.
Symptoms of a Bad TIPM: Jeep Grand Cherokee
Here are the most common symptoms of a bad TIPM:
Won’t Start
The TIPM can keep the fuel pump from coming on. When this happens, your Grand Cherokee will turn over, but it won’t start.
Dead Battery
The TIPM can leave your Grand Cherokee’s fuel pump on, even after you remove the key from the ignition. You don’t need to worry about it leaking gas, it’ll just keep the fuel line pressurized and slowly drain the battery.
Stalling
When the TIPM goes bad, the fuel pump may not properly function and send enough fuel pressure to the fuel rail. When this happens, there’ll be stalling until the fuel pressure builds back up, or the engine will die when it’s all gone.
TIPM Repair
Here’s a great video on how to test and even bypass the fuel pump and relay on a TIPM.
If your TIPM has gone bad, you’ll need to have it repaired. Or, you can get a new one. They are pretty expensive. Sending it off and having it repaired is more cost effective. The only downside is that without a TIPM, your Chrysler made vehicle is dead in the water until you get it back.
If you are going to send off for a TIPM repair, there are shops online that specialize in just that, such as TIPM rebuilders.
