SAI it is unknown.....tomorrow

 

Instrument cluster

 

When I did this with an 04 donor into an 03 truck (both 4.6 w/SAI) I didn't know about the IDM sync. I must've had the ignition on for ~20m because there were no issues. I swapped ECU, BCU, TCU, SLABS, trans/transfer case, cluster, ignition and driver's door (because the 03 had no fob) and so far it's been 17k trouble-free miles. The only hiccup was one year I forgot to tell the inspection station that the VIN stored in the ECU would not match the paperwork, he got a little excited about that.

 

the elements to change would be: ecu, bcu, excitation coil in the key.
when you say IC do you mean where the odometer is installed?

 

unequipped !

 

no, it is a problem of immobilization of the unit. change harness parts. for start.

 

ok. is neccesary for odo. investigate this. I only have the issue that when changing the IC the aesthetics are different between models. but it does not matter

 

really is very interesant this change. provides new knowledge.
thak all!

 

You should not need to mess with the key or the key coil. Just change the entire instrument cluster.

 

yes, the best way!I have 2 controls already repaired this afternoon.....and tomorrow is the big day. if they don't work...change parts
