Jeep Cars & Trucks - Recent Questions, Troubleshooting & Support

If there's nothing wrong with your coolant levels, your motor oil, or your battery, and your car still won't start in hot weather, it could indicate a deeper issue with your engine. Your coolant temperature sensor might be broken, for instance, which means that the engine will "think" it's hotter than it is.

Bare or burned wire, most likely battery cable or alternator cable near exhaust system which might be making contact with a metal part somewhere, off and on, because of bumps, vibration, etc.

Resetting a Vehicle Anti-Theft System
This is how you reset an anti theft system if you have the anti-theft light on, or your car is cranking, but you have no spark.

Doing a full reset of the anti-theft system.

Disconnect both battery leads for at least two hours.
Hold the negative and positive leads together for 5 minutes to fully discharge any power.
Put the key in the ignition, but not turned on. VERY IMPORTANT!
Connect the positive lead.
Connect the negative lead in one swift movement.
Wait 15 minutes for the system to fully reset.

The IOD fuse is located in the IPM (Intelligent Power Module - a fancy term for the main fuse box) which is in the engine compartment right next to the battery.

Have you checked the injectors? Try this.
**BE CAREFUL as you will be doing this with the engine running**
Using a very very long screwdriver or a set of extension bars out of a socket set. (The longer the better)! Touch one end to the first fuel injector and the other to your ear. Listen. A good injector will 'purr' regular and evenly, a bad one will sound uneven and rough. Do this for each injector, one at a time. If you have a GOOD helper you can get them to **GENTLY** press the accelerator a small amount to get the injectors working a bit faster. The sound should stay as a 'purr' but faster.

Nobody is going to send you 200 pages of wiring diagrams, expeically without knowing model and engine. See this post on how to find wiring diagrams.

your not in The USA posted to USA forum that has no such car.
Where is your car on earth? cars are not the same, by where sold. ok?: LAWS vary wildly and soon to get worse.
IN the USA we have only a 2002 Liberty. no such car like yours.
and guess what our books are no the same no is the car.
scan to PCM for DTC errors using a OBD2 scan tool
or get a SHOP to diagnose your transmission.

your car needs service, check fuses first.?
many cars like this have no A/T dip stick now,
due to owers wrecking the fluid , over and over, and so they got rid of that, #1 wrong act, using wrong fluid, #2 adding too much and causing foam up and bearing starvation and then seized parts.
first scan it, ok? or ask a real shop to do that and for sure a scan tool with Jeeps, P1xxx codes, Jeep factor codes supported.

stop do not wreck your transmission as most do (noobs)
it must be the right fluid , do NOT GUESS>
it must be done with the transmission hot, and levels vary by the exact temperature it is at now.
do not guess
why not let jeep or any ASE PRO shop do this and avoid you wrecking a $3000 BOX>
ok is that clear,

asking how much tells me you do not know A/T at all.

Jeep Cars &... | Answered on Feb 29, 2020

old post and so wrong..... seen this endless for noobs, and jeeps.
DTC jeep.
p1 is factory code
P17 - tranny.
first off many jeeps have 2 or more transmissions options new.
this car has 6 different transmission and engine choices new
sure the CVT box you have,
the other 3 are M/T boxes (stick shifted)

ever worked on modern A/T boxes seems not to me.
for sure not CVT boxes nor Jeeps. with it.

first off do not read non jeep books or that DTC code you will read lies. P1 is jeep only code. called factory jeep codes.
P0 codes are federal generic codes
P1 ,P2, and up are factory codes JEEP.

Transmission Ratio Control Circuit (Failure it is)
off the real service manual it states

P1729-TRANSMISSION RATIO CONTROL CIRCUIT For a complete wiring diagram, refer to the Wiring Information.
Theory of Operation
The Transmission Control Module monitors and controls the gear ratio by the use of a Step motor that transfers electrical power to mechanical movement. The rationality is a continuous test that monitors the Step motor movement. If the Step motor ON/OFF status does not match the TCM requested ON/OFF status a DTC will set.
  • When Monitored:
Ignition on with a system voltage between 9.0 and 16.0 volts.
  • Set Condition: If the Step motor ON/OFF status does not match the TCM requested ON/OFF status for the period of 200 msec the DTC will set. It takes two consecutive problem identification trips to illuminate the MIL.
this means the stepper motor in the transmission is failing
via the .
wiring from it to box bad (box = tranny as in gear box)
wiring at box or inside box bad.
or the Stepper motor inside is shorted, or open or bad.
the manual shows checking voltage and ohm here , got the manual.
even at

only jeep can fix this, for sure to find true cause

they have in the jeep shop the CVS testing system you do not have.
nor anyone else.
