Transmission Control System Electrical=P0702 code,
Have you talked to a jeep dealer yet,
Ask if there are any TSB's on this problem.
Technical Service Bulletins from Jeep when they find and solve different complaints.
What ever is doing this is a soft code,A soft code is one that will clear it's self with the cycle of the key to off then on and code goes away,But have them check history codes to see if it is there.it sounds like it is going into limp mode,this feature is when the computer sees a transmission falt it wont up shift,so you don't harm the tranny,but will let you limp to a shop to get repaired.have you ever noticed the speedometer going to 0 then this happens?
that would be the output sensor.

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.
