Cruise COntrol

[fixkick]

My cruise control doesnt work. Some history on my car 1994 Sidekick. Automatic 4wd, Fed emissions 4 door. 1.6 16V.
Previous owner put in a newer transfer case. 16 spline instead of 26 spline. Speedo reads 10mph too high but whatever. lol. I have no idea how to diagnose the cruise control. I checked all the usual things (fuses connections etc) so I have no idea where to even begin. Everything looks like its there as the previous owner was older and disnt tinker with it just drove it. Thanx

ok the rare car with  cruise, option 
sure fuses are first.
it has 2 major parts the cruise module in the dash not missing, 1st.
then the motor near TB and cable to run the TB throttle valve called the cruise TV cable.

yes , the cruise model pins  must be reading correctly

using a  voltmeter.
the MPH off there is not a problem at all.
the brake switch for cruise, not bad.
the transmission  i guess is the 4speed autmatic with OD. I guess due to 4doors, needs HD tranny due to more weight of car and loads.
PRNDL switch must show in Drive . or cruise is canceled.

no sure what year this is but the progressives are the same.(cruise box logic>)

IG coil fues not blown if is blow spark ends so is not blown
Stop light fuse not blown,, (rear of car see them work) then not blown.
Module cruise  not missing,
VSS clicks,  NO DTC errors for VSS1 or VSS2 dead,  one inside speedo cluster and one on tranny trail shaft or transfer case rear, DTC errors for either , if they fail. (flashing DTC codes ECU)
vss is the veh, speed clicker. clicks per mile. (tells it you e are moving now and not parked.
as you can see both stop switches must be good , one tap brake pedal and cruise ends. now.
CRUISE dash switch not missing or dead.
steering stock lever switches x3 cruise not bad. or missing or unplugged from harness.
Not in Neutral nor park  but in drive, mode. PRNLD.
the ECU has 2 wire there for communications, tells the ECU it has throttle (TH)   controls now.  and ODC , overdrive mode is cancel, means can not be in OD mode. tranny.

VSS


seems simple but is not,
