vincentmoy Posted February 9, 2009 Share Posted February 9, 2009 Hi all, finally got the TDC from my 93 Loyale AT w/ 133k mi. It is showing 45 (if I read it correctly - 4 long blink with 5 short blink, then repeat itself over and over). I looked it up from chilton and the USMB and it is something related to the kickdown control relay - continuously in ON/OFF position. What is that? That doesn't seems to help me with my problem about my high speed perf. Anyone has idea? Thanks! Vincent Link to comment Share on other sites More sharing options...
MR_Loyale Posted February 9, 2009 Share Posted February 9, 2009 I am going to take a stab here and others can chime in to tell me I am nuts. I think the kickdown code is related to the automatic transmission. It is part of controlling of hydraulic pressure for switching gears when you stomp on the peddle. Now this seems to make sense if you cannot get above a certain speed. Does engine continue to rev high RPM's but you just don't go any faster? It looks like the relay is an inexpensive part that sits behind the glove box that you can replace yourself. Unplug the old, plug in the new. $12.25 http://www.bestsourceautoparts.com/partsCatalog/geturl/quote/year/1990/make/SU/model/LOY-4WD-001/product/P2020-33062/application/000363207/part/Relay Link to comment Share on other sites More sharing options...
vincentmoy Posted February 9, 2009 Author Share Posted February 9, 2009 No, the Eng won't rev up much neither. The techo will drop when I'm traveling @ around 45 mph. It shift normal in 1st and 2nd, the rpm drop only happen in 3rd @ around 45mph. Even you floor the gas it still won't accelerate, but if you let go a little it will accelerate again.... do you get what I mean?:-\ Vincent Link to comment Share on other sites More sharing options...
MR_Loyale Posted February 9, 2009 Share Posted February 9, 2009 I'd try changing that relay. It is cheap and that is what the ECU is reporting. Link to comment Share on other sites More sharing options...
vincentmoy Posted February 9, 2009 Author Share Posted February 9, 2009 I might as well... Got to wait till I have $$ first... But thanks! By the way, how do I get access to the relay? How to I remove the glove box and how do I know where is the relay? Vincent Link to comment Share on other sites More sharing options...
MR_Loyale Posted February 10, 2009 Share Posted February 10, 2009 Well on my 93 Loyale, I open the glove box all the way. Then back off slightly and squeeze both of the side walls of the door. Now open the glove box all the way and the detentes should clear the catches. Go the the website I showed and look at the photo. Your relay should look like that one.
