On a search, I see people confusing it with the OBD2 connector (which is in the cabin under the dash) -- but what diagnostics are available in this alternate connector, and what diagnostic tool accesses its data?
Most likely Toyota specific with them having the access to the tool, not sure just my best guess. Typically OBD2 is mandated, everything else is proprietary, meaning manufacturer only. If I'm wrong someone will be here shortly to correct me.
As far as I know, it is just an old Toyota diagnostic port. I wanna say we used a Snap-On diagnostic tool that had that add-on but we only used it once and I am not sure what it did. OBDII at this point should do whatever you need so it is best to just ignore the port.
On the older Toyotas with OBD1, you would jumper the TE1 & E1 terminals in there to get into diag mode, where the CEL would blink out the error codes. You could also:
Force the fuel pump to run with KOEO (jumper FP to +B)
Read fueling corrections by probing voltage across VF1-E1 & VF2-E1
Read O2 sensor voltage signals across OX1-E1 & OX2-E1
Read ABS faults (jumper TC-E1)
Force radiator fans to run (jumper OP1-E1)
There should be a label on the underside of the cap denoting the terminal IDs. As time passed, some of the terminal positions were depopulated, so the function was lost.
I think one needs to understand that while OBDII is standardized, there is still a lot of non-standardized manufacturer specific extra stuff that's not part of OBDII standards. You need yet still another scanner, or a much more expensive OBDII scanner to do things like air bag, abs, key fob programming, and these functions would be different for different manufacturers. The standardized OBDII stuff has more to do with emissions.
Hello everyone, I'm new here and this topic came up once and I dont know if the issue was ever resolved, I have a 2004 avalon, when cold the car runs great, after 5 or 10 min warmup, while driving it's like it has a 4kish rev limiter, its smooth up to the 4kish but at 4k, that's it... car has 0...
I bought this to replace the sub I used to replace the factory subwoofer. The one I was using never filled the bass that was missing. It is a Pioneer designed to work free air and in a box. This is a dual 2 ohm voice coil 8". It is a little wide but I managed to get it to fit. My stereo...
I'm about to have to abandon my 2000 Toyota Avalon v6 3.0 (all Avalons have this and only this engine) with 78K miles because I can't get rid of a diagnostic "Cat not ready" message. Everything else passes fine. Car runs fine, rather better after changing the sensors. If I can't pass CA smog, I...
Still doing some touch up repairs on my 2000 Avalon. Front passenger door power window switch was broken, as was the passeenger door latch bezel. Easy DIY. Here is a video if you have to remove the power lock/window switch on your Avalon. $12 in parts from salvage yard.
Hey everyone, I own a 2004 Avalon with 102k miles completely stock. Wondering if it was true that you can use coilovers for a 2001 camry on the 04 avalon. Idk if it's true but if anyone knows It would truly be helpful. Hope y'all have a great day.
