This may sound strange, but I have seen this code many times. Check all fusesin the power distribution center under the hood. I bet you find a blown fuse...ALSO check your relay. It is probably bad too."Radiator Fan Ctrl Relay Circ" Maybe the computer thinks the fan's misbehaving, so it backs off the power? Hope this helps, James Booth

1999 Jeep Grand Cherokee Laredo 8Cyl4.7L When when driving over 50 miles per hour will lose all power whats wrong?


When you say it loses power, do you mean electrical power or engine power ?
You would need to look at the fuse boxes for a loss of electrical power, and use a scanner or code reader to check the computer for trouble codes for a loss of engine power.

My 2002 jeep grand cherokee laredo wull not start shutdown 2 days ago checked all fuses but the ecu fuses don't know how to find them


According with your other quesions, the DTC P1491 code is actually radiator fan control relay circuit.
Soft reset if the battery disconnect would have erased the code; the first thing I would replace for that code (fan relay).
Additionally, its possible thta your THEFT system is activated, check owners manual to disarm. Check details here:
- Grand Cherokee fuses

- Diagnostic Trouble Codes

Hope this helps.
