Help!! dash light-VSC,ABS,trac off,Brake

PCH · 09-03-2009, 01:38 AM

I think with all the adaptors and latest software about $2K. May be they can get you a demo to play with.

Clearing ABS Codes:
1: Instal jumper between Terminals #4 and #13 of the OBD2 Connector

2: Turn the ignition key ON
3: Push brake pedal 8 times within 5 seconds

The car should be parked on level ground with the steering wheel centered. When no trouble codes present, the ABS light should flash continiously.
Toyota recommends using a tool SST 09843-18040 when no scanner available for ABS code clearing. The SST tool is basically a jumper wire.
I got this info from the Scion Repair Manual. Using a jumper wire (paper clip) instead of SST is talked about on various Toyota related sites so it's up to you to trust that.

OK, this is safe to do with a paperclip. Just did this on my 06.5. The panel lights flashed a code, then i pumped the brake pedal and it switched to steady flashing which means the memory in the ABS ECU has been erased.
Try it, Sid.

victor,
how long should the lights suppose to keep blinking??
i tried it, but the lights won't stop blinking, its like 2 blink for abs, then blink winth abs, then it just repeat and repeat.

took the keys out, took the clip out, start the car, lights still there.

i mean switching blinks with abs and vsc, then both of them together.

After you turn the key ON you get lots of flashes. Those are trouble codes. For example it flashes 4 times, then a short pause, then 3 flashes, then a long pause- thats a code 43. Then it will repeat again, or flash a different code if there is more than one stored in the memory.
After you press the pedal 8 times within 5 seconds the lights should start blinking fast. Try doing this a few times. I believe if there is a continiuos fault in the system then the trouble code is set immediately so it can not be cleared untill it's fixed.
If nothing helps try counting the flashes and record the code numbers. I'll see if i can find the definition.

i tried it again, still there. i video the dash light flash, but my cam recorded it on avi, it takes soo long to upload a minute take, so i cancell the upload to youtube.
damn hard to explain the flashes.

got it converted to mpeg, uploaded.

23 SRR Solenoid circuit. (Can be an internal problem with Skid Control ECU/actuator assembly)
41 Battery Voltage too high or too low (Battery, Charging system or Power Source circuit problems).

Make sure the parking brake is off when you reset those codes. Check all fuses again. Other than that there is probably not much you can do.

sid, have you talked to "victorr"? this is his sig, LAUNCH-USA does he work for them? hummm....

sid · 09-03-2009, 09:18 PM

thanks victor, i guess i just have to drive it this way for now

hey eric, i might give him a call tonight or tomorrow, he's a busy guy, but i hope he got those techie stuff in the office for product trials & testing

Toup · 09-03-2009, 09:20 PM

I think I've heard of people covering the lights with electrical tape because its such a common thing. Won't stop them but you won't see them... LOL

eggie · 10-12-2009, 03:56 PM

Hey i'm currently in this group. Any new info?

Mine is different because I had ask a jackass for a jump and he put the cable on his end wrong.

sid · 10-12-2009, 05:05 PM

come to think of it, that is prolly my initial cause. but it didn't happen right away. after we corrected the jump, no warning lights. Only after i took off the ground wire. I am still driving with those lights on. still looking for a fix or free dealer hook up to clear this.

eggie · 10-12-2009, 05:06 PM

Quick background on my crap:
1. pulled hegative cable - nothing
2. pulled neg. + turned key to on - nothing
3. pulled efi fuse - nothing
4. optima battery is going south. Just like Sid, if I don't drive the car for 2-3 days the car is hard or doesn't want to start.
5. hooked up my obdII scanner and it doesn't show any codes

PCH · 10-12-2009, 05:28 PM

So are you going to read ABS codes?

eggie · 10-12-2009, 10:42 PM

I don't see any ABS codes. If I saw any codes it would make this much easier, but the scanner shows nothing. I'll check again.

PCH · 10-12-2009, 11:20 PM

You don't have to hook up a scanner to read ABS codes.

eggie · 10-13-2009, 12:22 PM

Oh, I just read more of the above. I'll try the clip thing. Maybe tomorrow if I have time.

Ok, I think this is correct:

abs = 23 or 2 blinks, pause, 3 blinks
vsc = 43 or 4 blinks, pause, 3 blinks

PCH · 10-13-2009, 12:36 PM

43 is either Yaw Rate Sensor or a general ABS system problem. Things probably got damaged when jumpstarting the car. Electronics are really sensitive to voltage surges and reverse polarity. Sucks, but you may have to take it to the dealer if the codes can't be cleared.

eggie · 10-13-2009, 05:28 PM

I'm going to check my abs fuses later today or tomorrow

whats abs 23 mean? broken electrical connection right?

PCH · 10-13-2009, 05:33 PM

SRR solenoid inside the ABS assembly or ECU problem. Sid got that code too after jump start.

eggie · 10-13-2009, 10:30 PM
