Hi ya peoples. Ok - heres the situation. We have this altezza (beams engine, tiptronic auto) and its proving very problematic.

1) engine check light is on.
2) only the first 2? gears are avail for use - it just wont shift up
3) toptronic mode wont work
4) very poor acceleration

now - do toyota ECU's have a limp mode? If so then its mny guess that thats what its running in. The reason behind this i really dont know...

Any thoughts / advice would be very appreciated!!!!

thanks

AL

PS - apparently this car has been into toyota NZ and their verdict was stuffed ECU. The ECU has since been repaired but still no go.

Have you tried putting it in test mode to check for any error codes?

by **Crimson Tears** » Sun Jul 18, 2004 3:17 am

Hey,

They most definitely do have a limp home mode.

As Xyrath said, put it in diagnosis mode and check the codes. Look for a little black box labeled 'diagnosis' and short TE1 and E1, the engine check light should flash out a pattern to indicate the code

eg: flash flash, flash flash flash flash

would indicate code 24.

Cheers,

Mike

Corey's in Christchurch.

PM me if you want his details.

OK - just looked up the toyota error codes and was about to test it out and see what i got, but in the diagnostic panel in the engine bay theres no electrical connector (nor wire feeding into the back of the diagnostic box) for the terminal TE1 ?!?! How on earth do i short TE1 and E1 when i only have one of these terminals!

Help please!!!!

:roll:

ok - found 16 pin OBD2 connector under dash with 6 wires going into it. Are any of these TE1 and E1? If so, which pins? (Ive searched the i-net and cant find a thing). Or do you need some form of scanner to access the ECU error codes on OBD2 systems?

Thanks

That's because it's not TE1 & E1 on that style of connector, it's TC & CG as shown in the diagram below.

You may be lucky and be able to read the basic codes using a jumper and not need a scan tool. Works on a GT-T, not sure about the Altezza though.

Thanks fivebob - i was hopin you would come to the rescue ;-)

I will give it a try tomorrow.

OK - im gettin codes 41 and 89.... dont happen to know what they are do ya?

41 = Throttle Position sensor
89 = TRAC ECU Circuit

by **TWSTD** » Mon Jul 19, 2004 3:05 pm

I assume TRAC ECU Circuit is an internal ECU component?

Re TPS - is there any way i can test the TPS sensor to see if it is functioning normally or if it is indeed faulty?

Turbo tezza - please get in touch and we can discuss the loan and or purchase of your spare ECU. If poss i would like to try installing your ECU prior to purchase just in case the problem is in fact elsewhere.

by **TWSTD** » Mon Jul 19, 2004 3:09 pm

noooo - these things have traction control right? thats what the TRAC ECU error code will be about right? Wheres the traction controll ECU located anyone know?

by **fivebob** » Mon Jul 19, 2004 3:11 pm

TPS is easy to check with a Ohmmeter, I don't have the specs handy right now, but it should be a 0-5v signal + an idle switch if it's standard Toyota.

I found some more info on the Code 89, but it's in russian and the babelfish translation is somewhat garbled. It would appear that it's probably related to the TPS problem, it refers to the ECT-S (Electronic Throttle Control System) does you car have an electronic throttle?

by **TWSTD** » Mon Jul 19, 2004 3:14 pm

its got some form of traction control system - is that the same as electronic throttle control? I dont know much about these vehicles as its not actually my own car.

by **TWSTD** » Mon Jul 19, 2004 3:18 pm

I also have a russian friend who should be able to translate - what was that link you found? this one? http://efisakh.narod.ru/at_540.htm

by **fivebob** » Mon Jul 19, 2004 3:18 pm

Have a look at this page and see if it looks familiar, there's plenty of info about testing, fail safes, limp modes and even a TPS voltage graph.

No it was http://www.toyota-rus.narod.ru/files/04 ... m_etcs.htm it seems to be about actual repair cases and about 3/4 way down the page there is a bit headed

1999 Toyota Altezza RHD TMC Japan.
Engine: 3S-GE 2.0 L / 4 cyl / Gas / Dual VVT-i / BEAMS
Fuel: Fuel Injection
Mileage: 29385 km
Model: SXE10-AEFVF

which babelfish translates to;

Symptoms: Increased revolutions KHKH of thoroughly heated engine, "neznachitel'naya reaktsiya" engine to the pressing of the pedal of gas, the lamp of "Chyuechk Engine" it continues to burn with the brought engine. First of all were schitany the codes of self-diagnosis. Using "tekhnologiyu" Without Scan Tools: -), schitan the code of self-diagnosis (MIL-code) 89 (malfunction of the drive of the choke of "zaslonki" - ETCS malfunction). Malfunction is localized, but this information it is clearly insufficient. With the malfunction of this system there can be schitany the following codes of self-diagnosis (SAE and Manufacturer ** DTC):
DTC P0505: IDLE Control System Malfunction
DTC P1120: APPS Circuit Malfunction
DTC P1121: APPS Range Problem
DTC P1125: THROTTLE CONTROL MOTOR Circuit Malfunction
DTC P1126: ELECTROMAGNETIC CLUTCH Circuit Malfunction
DTC P1127: ETCS ACTUATOR POWER SOURCE Circuit Malfunction
DTC P1128: THROTTLE CONTROL MOTOR LOCK Malfunction
DTC P1129: ETCS Malfunction Scanner OBDII of "popolnil" information since with its aid there was schitan code DTC P1128. After checking of the drive of shutter appeared the wedging of the rotor of engine (consequence of the prolonged of "prostoya" machine). The essence of malfunction consisted in the fact that after ignition YESM it attempted (unsuccessfully) to conduct positioning shutter. Naturally shutter in this case was not moved and, as a result, did not change voltage on the sensor of its position (TPS) Therefore YESM correctly considered defective the transmission system of motion. The replacement of rear spin bearing completely removed the problems of automobile.

Thanks for that - i will look further into it tonite :-)
