Jellybean Posted June 15, 2015 Share Posted June 15, 2015 She is a manual 6 speed , Slip Cont off flashes after some WOT , I have not yet done a quiet drive yet The light will keep flashing very 2-3 secs Car is just back on the road , there are no error codes, I did reset the ECU; in the morning when I start her she is fine until I do a WOT Things done to the car Rear wheel Bearing Both rear Abs sensors disconnected and reconnected Rear diff rebuilt and installed Prop carrier bearing New Rear brake discs Any idea's, recheck the ABS sensor connections?

Chris Wilson Posted June 16, 2015 Share Posted June 16, 2015 If an ABS sensor was dead or shorted or disconnected you would have an ABS light showing. Have you fiddled with the throttle body in any way? Quote Link to comment Share on other sites More sharing options...
Chris88 Posted June 16, 2015 Share Posted June 16, 2015 Could be an issue with a speed delimiter/speed converter (if you have one). The HKS literature for the type II and T6 both describe flashing of the TRC/slip control light when you go over the previously limited speed.

Did not touch the throttle side, but it is my next point of call this morning, maybe something is loose This only started to happen after I was able to give her a good spirited drive of the year Quote Link to comment Share on other sites More sharing options...

Thanks but no speed converter is required on mine , she has a sard analyse rom in the ecu so the delimiter would not be an issue Quote Link to comment Share on other sites More sharing options...
Jellybean Posted June 16, 2015 Author Share Posted June 16, 2015 Just checked , throttle section all looks good, no loose cables/plugs Could it be anything to do with how she detects slip, maybe the sensor dirty , Which solenoid is the trac? If I did pull the fuse on the trac, would the light be constantly flashing , just for mot time, how do you get around it Quote Link to comment Share on other sites More sharing options...
Jellybean Posted June 17, 2015 Author Share Posted June 17, 2015 I am a bit perplexed by this , no engine codes to run off , nothing logged Anybody any Idea's? Quote Link to comment Share on other sites More sharing options...
Tyson Posted June 17, 2015 Share Posted June 17, 2015 Slip cont is only for auto's isn't it ? Has yours been converted to manual ? Mine hasn't got a slip cont light or is it an import thing ? Quote Link to comment Share on other sites More sharing options...

Jellybean Posted June 18, 2015 Author Share Posted June 18, 2015 (edited) Getting an error code 34 , turbo pressure malfunction I changed all the Vacuum hoses , would this cause the light to come on though? My guess is throttle valve ? http://www.mkivsupra.net/vbb/showthread.php?35920-How-To-Check-the-diagnostics-codes Edited June 18, 2015 by Jellybean (see edit history) Quote Link to comment Share on other sites More sharing options...
Jellybean Posted June 18, 2015 Author Share Posted June 18, 2015 Scrub that, I did hot fuel cut / boost cut the the other nite Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 18, 2015 Share Posted June 18, 2015 Yes, hitting boost cut will leave that code and put the TC light on. Is the FCD installed properly, assuming a stock ecu? Quote Link to comment Share on other sites More sharing options...
ellis Posted June 18, 2015 Share Posted June 18, 2015 I've still got this issue - flashing O/D off light and flashing TC light too - both been like that for a year now! I have half BPU and no FCD etc. Current thinking is speed converter but nothing solid has ever come of this diagnosis, not been able to test the theory yet.

Samurai 20V Posted June 18, 2015 Share Posted June 18, 2015 I had a similar issue, trac ecu was stuffed. Replaced with a 2nd hand working one, perfect.. Quote Link to comment Share on other sites More sharing options...
Jellybean Posted June 18, 2015 Author Share Posted June 18, 2015 Yes, hitting boost cut will leave that code and put the TC light on. Is the FCD installed properly, assuming a stock ecu? Sard Analyse ECU so boost cut is raised to 1.3 via a ROM chip , it was late and once the temp dropped she spiked to 1.3, had to dial back the duty cycle Quote Link to comment Share on other sites More sharing options...
Jellybean Posted June 18, 2015 Author Share Posted June 18, 2015 I had a similar issue, trac ecu was stuffed. Replaced with a 2nd hand working one, perfect.. Just too coincidental for it to be stuffed after I just put it back on the road Trac on it is crap, not too pushed if it is gone when you take out the ECU or fuse for the Trac, will the light stay on constant I presume? not an MOT failure?

Jellybean Posted June 18, 2015 Author Share Posted June 18, 2015 From what I gather, Trac fuse will cause Slip cont lights to illuminante constantly , so best to just unplug the ECU with traction control on it in the passenger footwell Quote Link to comment Share on other sites More sharing options...
Jellybean Posted June 18, 2015 Author Share Posted June 18, 2015 This is the trac ecu? Quote Link to comment Share on other sites More sharing options...
berg Posted June 18, 2015 Share Posted June 18, 2015 Yes thats the one I have the slip cont off and o/d lights on mine I have tried the following which has made no change 1. Tried the car with no speed converter/delimiter at all 2. re-soldered all wires for the above and triple checked against diagram 3. Tried a spare ODO 4. Replaced Throttle control ECU 5. checked resistance on the sub throttle control valve and sub TPS on the throttle body 6. Replaced both the fuse and relay for traction control 7. checked speed sensor Mine has to be something to do with the valves on throttle body Need a place near the midlands to sort it for me but yet to find anyone Quote Link to comment Share on other sites More sharing options...
Jellybean Posted June 18, 2015 Author Share Posted June 18, 2015 I don't have an issue with the odo just the trac light, I reckon it keeps thinking its detecting slip and just gets confused, traction control never kicks in but seems to start constantly flashing after I pull off from gravel or put the foot , down ; even though there's no wheel slip, I think it just gets confused and doesn't know what to do No engine codes , car is going like a train, no loose connections around the throttle body Quote Link to comment Share on other sites More sharing options...

Did you ever managed to solve the slip control light on issue ? Everything works as it should , my car is stock RZ TT6 facelift with only an exhaust , and after I start driving it for a while the TRAC SLIP CONTROL light flashes after 2-3 seconds continuesly till I turn of the car, same as yours , only difference yours is prefacelift mine is facelift.

Chris Wilson Posted January 5, 2023 Share Posted January 5, 2023 Borrow a TRAC ecu from a known good car and see if that fixes it, I see a lot of duff TRAC and engine control ecu's these days, finding a good one is a nightmare. Doing all the tests to show if the car has other issues causing the light to flash takes ages, so best to check if it;s the ecu's first.

rider Posted January 5, 2023 Share Posted January 5, 2023 (edited) I have this problem and plan, one day, to take the ECU covers off to see if there are any failed capacitors. Pending that day I have just disconnected the trac ECU which puts the light out. I have talked with tuners about having a new engine/trac ECU setup but they were all too busy to fit me in and the quotes started at £5k. Which makes disconnecting the cheap and no real issue option. PS - When I checked last year this ECU was still available as a 'new' part at £1,200 + freight + VAT + duty. But that is probably a 20 year old new ECU anyway.
