I'm looking for info on the OBD-II connection in the AE111. Just general research shows that CAN protocol for our gen. toyotas is should be ISO 9141-2. Does anyone know if this is so? Where abouts is the connector, is it on the ECU behind the headunit (according to schematics on toyodiy)? |

It should be the diagnostic port in the engine bay. |

you would need a toyota scaner that plugs into the diagnostic port, no obd plugs |

So the ae111 doesn't have a standard OBDII port? Where abouts in the engine bay is the diagnostic port? |

just bridge the diagnostic connector and read the engine light flashes... will give any info you need... why do you want to connect up? |

Going to add a computer to the car, set it up with touchscreen for gps, mp3 and vids. Also want to get obdII readouts so that I can monitor it through the display. I've been googling, but can't seem to determine whether the 20v BT is OBDII or not, getting hits saying yes it is and others contradicting it. Where abouts is the diagnostic port located? ------------------------------------------------- Found the port, right next to the fuse box, not sure why I didn't notice it..... I'm pretty sure that's not an OBDII port, so looks like that monitoring idea is down the drain.... Edited by blah, Dec 11 2008, 01:19 PM.

There are no OBDII plug in the AE111. I've try hooking up a Greddy touch informer, but googled and found that there are actually no OBDII plug. Then I've try to find a conversion plug for our diagnostic to OBDII, which also does not exists. The conclusion from googling is that if your car have "diagnostic" there are no OBDII. The diagnostic plug is at the front right behind the air filter next to the coil. |

You will need the special software wich will be hard to aquire and also the leads. Reamember the AE111 does not have the OBDII connector socket that vehicles have over here Dont know about you but my local Toyota dealer could only cater for OBDII fitted cars, Not grey imports Checking what exactly? For a code read (if they can do it) will probaly be charged at 1/2 hours labour |

As Ace said, you'd be paying someone to do what you could do yourself in about 60seconds. Get a paper clip, unravel it, open the diagnostic port cover in the engine bay, stick one end of the clip in E1 and one end in TE1, get in the car and turn the key to ACC and count how many times the CEL flashes, then match that to the relevant problem. Codes and problems can be found online. |

ecu will only give sensor faults that it can detect... like a oxy sensor will keep having a output but its wont be correct the ecu dosnt detect the oxy heater if that's blown. If you have a blocked fuel filter/bad plugs/leads all that kind of thing the ecu wont pick it up... Most of the time if the ecu has codes the cel will come on while your driving. Newer cars the ecu detects alot more but it also can be a pain... silly little things that may not matter get picked up or you replace a part that's non oem it wont fix the problem. |

oh dear, its the turbo version. so you add the 2 codes together? with honda it would be 1 long flash then 2 short flashes to make 12. can anyone confirm what toyota codes do? thanks for your help Jase. so just to re-cap, it flashed once, paused then flashed twice, paused then flashed 3 times, paused then flashed 4 times. cheers guys |

I would assume that the it'll be the same as a NZ new delivered Corolla (4AFE). According to manual its Tc and E1Some dealers are nice and may not charge to chuck the tester onto a car You can check the o2 sensor by pluging in the correct tester and watching its operation. Very cool to see that your o2 sensor is doing what it should be |
