Transmanaiconmc Posted May 14, 2003 Share Posted May 14, 2003 I have an intermittent problem with the car losing all power to the accelerator and the 'engine warning light' coming on. Turning off and then restarting the ignition clears the problem temporarily. This problem then logs an error code 19. Quote Link to comment Share on other sites More sharing options...
mos Posted May 14, 2003 Share Posted May 14, 2003 Are you sure its 19 i dont have a 19 listed in the manual, are you automatic or manual?. Quote Link to comment Share on other sites More sharing options...
Transmanaiconmc Posted May 14, 2003 Author Share Posted May 14, 2003 The car is 6-speed manual. A toyota Dealer (Stratford) is telling me it is code 19? But I have never heard of code 19 (and neither have they), this is the problem. So they do not know how to isolate the fault. Incidentally, it is they who have caused the problem in the first place.

mos Posted May 14, 2003 Share Posted May 14, 2003 I will post tomorrow how to check the code for yourself. It is really easy to do and involves one wire, evrybody should learn how to check their own engine codes as the people on this site have a wealth of knowledge and can save you £££££. Also the supra is a specialist car, i tend not to trust toyota dealers as some have never even worked on one before Quote Link to comment Share on other sites More sharing options...

mos Posted May 14, 2003 Share Posted May 14, 2003 Well no point teling you now its on the click link how to do it but if you have snags then let us know and we can go through it, what were toyota doing it may help us narrow it down and have you tried an ecu reset, its a long shot but may work. Remove the efi fuse in engine bay fuse panel for at least 10 seconds and this will reset the ecu or disconnect the battery for the same amount of time Quote Link to comment Share on other sites More sharing options...

Also the supra is a specialist car, i tend not to trust toyota dealers as some have never even worked on one before dont you check the codes by connecting T1 TE1 by a wire of the diagnostic check connector which is inside the car, driver side ?

Terminator Posted May 15, 2003 Share Posted May 15, 2003 Try E1 and TE1 as 0n page 589 of the engine manual. Codes are stored in order, smallest number to largest number witha 2.5 second gap between codes. Quote Link to comment Share on other sites More sharing options...
Transmanaiconmc Posted May 16, 2003 Author Share Posted May 16, 2003 I must be doing something wrong, I have connected copper wire to TE1 & E1 and the engine light just sits there permanently on? I have tried this by connecting wire after switching ignition on and also before swithing ignition on any ideas guys? Quote Link to comment Share on other sites More sharing options...
Terminator Posted May 16, 2003 Share Posted May 16, 2003 If the engine light remains on when engine is running indicates a fault. Connecting TE1 and E! with enging off but ignition on should give codes. Have you tried both check connectors ie engine bay and under the steering column? I made a wire tool using flattend out mains lighting wire to get a good connection in the socket Quote Link to comment Share on other sites More sharing options...
Transmanaiconmc Posted May 16, 2003 Author Share Posted May 16, 2003 When engine is running, light does go off. But with ignition on, light just stays on permanently. I have tried both check connectors. Maybe the connection was poor I'll make up a new connector tomorrow and post results Thanks for the reply.

Guest Martin F Posted May 16, 2003 Share Posted May 16, 2003 You must link those terminals with the engine and ignition off and then switch on to activate diagnostic mode. Quote Link to comment Share on other sites More sharing options...
Terminator Posted May 16, 2003 Share Posted May 16, 2003 Martin are you sure, I thouht it was engine off ignition on the connect. I'll check the manual. If TE1 E1 connected does not produce blinking codes then it could be dirty TE1 E1 terminals, bad earth connection, open circuit in harness or short in harness or ECU fault. Page EG738 There should be a voltage of 9-14 V between TE! and E1 Quote Link to comment Share on other sites More sharing options...
Guest Martin F Posted May 16, 2003 Share Posted May 16, 2003 Originally posted by Terminator Martin are you sure, I thouht it was engine off ignition on the connect. I'll check the manual. Pretty sure unless my memory really is degenerating with all those mobile phones. Be good to double check though. Quote Link to comment Share on other sites More sharing options...
mos Posted May 17, 2003 Share Posted May 17, 2003 Is the red light staying on and the picture of the engine on the left hand warning light section, it is this yellow picture of the engine that flashes. Quote Link to comment Share on other sites More sharing options...
Transmanaiconmc Posted May 17, 2003 Author Share Posted May 17, 2003 Definitely cannot get error code reading. Terminator - I have checked TE1 & E1 in engine and under dash and there is no voltage with ignition on ? Quote Link to comment Share on other sites More sharing options...
mos Posted May 17, 2003 Share Posted May 17, 2003 Do you have an immobiliser/alarm and have you de-activated it before trying the test Quote Link to comment Share on other sites More sharing options...
Terminator Posted May 17, 2003 Share Posted May 17, 2003 Can’t help with alarm system Matt H may offer advice, but check plug connectors for bad contacts. The following is mostly taken from the UK engine manual and is the same for the JDM system. Diagnostic trouble code checkNormal Mode (BTW Martin Test Mode is ignition off before connecting TE2 and E1) Turn ignition on , connect terminals TE1 & E1 of TDCL (in cock pit) or Check connector engine bay. If no codes are out put check TE1 terminal circuit. Checking TE1 terminal circuit. With ignition on, voltage between TE1 & E1 in check connector and in TDCL check voltage between TE1, TE2 and E1 Voltage should be 9 – 14V If no voltage checks continuity of both TE1 terminals and body earth (ground). If no ground check connectors then harness, repair or replace. If there is a ground connection – check for open or short circuit in harness and connector between engine (&ECT) ECU and check connector and TDCL Check connectors then harness, repair or replace. If this does not fix it, it points to a problem with either the ECU connector or the ECU Lets hope its a wire or plug/connector problem.

Transmanaiconmc Posted May 18, 2003 Author Share Posted May 18, 2003 I have deactivated alarm, but still no voltage or flashing light. It is definitely the yellow picture of the engine I am looking at. Maybe there is a fault as 'Terminator ' suggests? This being a 98' import, could the test points be different to earlier models, (excuse my ignorance) Quote Link to comment Share on other sites More sharing options...
Terminator Posted May 18, 2003 Share Posted May 18, 2003 I don't have access to a manual for the late spec JDM car, I dont know of anyone who does. I doubt Toyota would have changed that much though, particularly in the diagnostics area. Quote Link to comment Share on other sites More sharing options...
