PC1571
PC1602
TC0027
RS0038

Also front inside of tires wearing faster than outter edge, Do i need to get the strut done? Anyone know what i should use to mount these emblems and were to get this missing lower door molding?

• PC1602 - Knock Sensor (KS) Module Performance
• TC0027 - Left Front Wheel Speed Sensor Continuity Malfunction
• RS0038 - Electronic Level Control Exhaust Valve Short to Ground/Open
• PZ2042 - Loss of ABS/TCS Serial Data Communications

PC1571: may be expensive...
Your on board computer is already at work, the dtc 71 code, is a EBTCM INTERNAL MALFUNCTION, WHICH SETS THE CODE P1571, WHICH is telling you that the electonic brake and traction control module ( EBTCM) IS not sending the PULSE WIDTH MODULATED SIGNAL to the program control module. YOUR EBTCM IS NOT COMMUNICATING WITH YOUR PROGRAM CONTROL MODULE, and the PCM, is turning off your traction control, which in turn, turns off your low gear, and the car starts is second gear by default. THE TRACTION CONTROL LIGHT ALSO STAYS LIT UP. If your car was built after the following VIN numbers, CONCOURS /DEVILLE 280478, ELDORADO 614516 SEVILLE 826978, YOU have one of the new EBTCM, PRIOR to these numbers your have the old style module, lets just say the old style module had some internal problems which tended to turn off your traction control, the new ones were much more reliable. First check your connections to your wheel speed sensors at each wheel, check the connection to the EBTCM, CLEAR the codes and see if it resets immediately without the car moving, if it resets with just turning the key on and you do not ever move the car, then more than likely you have an internal fault if you are sure you have good connections, the dealer has a wiring harness he can install to check and see if it is internal.

If I check connectors and all are clean and clear code and if it come back is this what i will need? Does OBD I or II matter on the ebtcm?

Wow these codes really have me scared now, they all sound like major fixes! Maybe i shoulda got an eldo with the 4.9. My moms eldo has 288k and has never had this many problems. Im overwhelmed with fear! Should i clean it up pretty and sell it?

nah
just take the time and run through them one by one
that module may be the source of most of those codes, everything on these cars are tied into one another keep that in mind

Just pulled the kickpanel on drivers side were i thought id find some sort of aftermarket alarm module, no module there, but "Ding frys are done" alarm installer managed to do a good hack job on all the wiring around the steering column. They even left the damn shock sensor on bottom of column. Grrrr i hate wire hackers. Any thoughts on a wiring diagram of a basic alarm that i could see online? Gotta go thru it and remove the two added fuses, added relay, wires, hood switch, siren, and trunk switch. Guess ill have to go with the ol' yellow to yellow, white to white color matching....hopefully. Also i noticed they ran the remote(blue) wire for the amp off one of the wires under there. Is there a remote wire and RCA comming out of factory bose unit? Well im glad i kinda paid attention in electrical class at auto school.
Whatta Nightmare!

do a search on systems, theres a thread about how to create rca's from the stock headunit dunno if it covered anything about remote wires though

9BlackN*Black6 · #11 (**permalink**) 03-08-07, 06:01 PM

theres a power wire and ground already ran for a stereo, i removed the carpet cover in the trunk and found a box wired in with the LR speaker, its got the RCA's comming outta box, finally something that i dont have to worry about...or do i? I guess ill find out when i put the system in hopefully amp and subs will be plug and play. Any ideas on any appoxy or glue i should use to put my emblems on landeo/vinyl roof?
Think i may have to go to a body shop and see if they have mounted any emblems, similar to my situation, and see what they used.
