Setting timing on a 2002 jeep grand cherokee

the nav (rec) head is too complex to stuff into the , cars users guide, have paper too, in my jeep, "no phy. time button , for sure"
so JEEP has a manual only for this one head.
85 pages.
solved.
get it and keep if for next time lost in the guts of NAV
the DVD_Rom slot 7 is not optional,. NAV DISC.!
nor is working GPS. and is the default.
for driving maps live all that is needed.
next time post a photo of your head like this.

see this ,see "REC"
bingo. if not bingo say it/?

Wiring, schematic, electrical diagrams, torq settings, parts info, error/fault codes, full assembly/dissembly, service instructions and a lot moreetc are basic contents of these online books they here on this website https://big-manuals.com/products/jeep-grand-cherokee-wg-2002-workshop-service-manual

Hope helps.

Your timing is locked. (distributor is installed with no adjustment feature... on 02's you may not even have a distributor as it's replaced by the cam sensor) All timing and fuel mixture is controlled by the engine computer. Main inputs to the computer that influence changes are the throttle position sensor and MAP sensor but all sensor inputs are evaluated.

the sensor assembly has to be set just right to be in time with motor

on four cylinders and inline sixes the gap is .035 as reccomended. but if the plugs are platinim, do not try to reset for they are set at factory. have a good day !!

hi
contact your jeep dealer as there was a recall for the grand cherokee heated seat pads as some of them heated to much and set the seat on fire... they will replace them free off charge.
hope this helps

CHANGE THE BATTERIES IN THE FOB, PUSH SET THE SET BUTTON ON HTE DOORIF THE FOB IS BLACK IT IS 1 AND GRAY IS 2, SET THE SEAT THEN PUSH THAT NUMBER

If the distributor syc is not set will cause the same problem

go too auto zone and buy a set on most cars they just snap on and off
