On hot days the P/S, VSC and ABS lights on my 2007 Rav4 come on and the Powersteering doesn't work and neither does the display on the panel that shows the time (although I can push buttons like the fan and the Air cond and they respond but ther is no visual indication of it).

By evening everything is back to normal and earlier in the morning all is OK too. I recently bought this car and the dealer is trying to fix it but it running out of ideas. They had the codes checked at Toyota twice with different results and they changed the ABS unit on advice from the Toyota dealer but to no avail. I changed the fuel cap as it seemed dodgy. It seemed to be good for a few days but is again back to showing the lights. These hot days are only around 32 degrees plus - which isn't unusual for a WA summer. I seem to be able to delay the problem longer by having the windows down to cool the cabin temp but it doesn't solve the issue.

The car drives perfectly well when the lights are not on.

Has anyone heard of this before - any ideas?

Update - one month later 2 Feb 2014.

I took the car back to the dealer in early January. It was sent to theToyota dealer they had the car for a week and apparently took the dash apart and found a loose connection under the dash somewhere. They then kept the car out in the sun on a very hot weekend (44 degrees C) and found no trouble and no codes.

I've had the car back for 3 weeks now and kept it parked in the sun on weekends and no problems.

So hopefully it is fixed now.

The dealer was great and persisted till it was fixed. Can't ask for more.

      1989 Hilux Low Voltage

      Hey all, recently got a 1989 Hilux with the petrol 22r engine. I had plugged a voltage meter into the 12v socket because I suspected an electrical problem as the battery light had been on. It had read 11.9 volts initially but the more I drive the more it deteriorates, currently sitting at 10.9 (after several hours of driving) when the engine is running. This obviously doesn't charge the battery and it can't start by itself. I have since replaced the battery and yesterday I did the alternator with a brand new one. I've checked all the grounds that I can see but it's still sitting at 10.9 volts and deteriorates over time. I was thinking the voltage regulator is the next best bet? I looked at it visually and it seems fine. Anyone got any other ideas? Note: I had a very long drive the other week and on one occasion the voltage spiked back up to 15+ volts for a short while before going back down to about 11.4 And yeah I'm trying not to drive it too much because I know it's probably damaging the battery being on such low voltage. Any help would be awesome thanks!

      FUEL WARNING MESSAGE

      Photo below showing remotely mounted relay for sup pump and switch to connect relay coil to earth when required. The earth connection for the switch was found using a test light in an empty relay socket just near where the relay is now mounted. You can trace the solid black wire. Btw, I soldered all the crimp connectors. I don't have a lot of faith in crimp connectors. Geoff

      FUEL WARNING MESSAGE

      No, I didn't see a fuel filter, but the inside of the tank was spotless. The pump wasn't running - blocked filter or not. Geoff

      FUEL WARNING MESSAGE

      Geoff, did you check the fuel filter that protects the transfer pump from blockages? Tony

      Wanting to build my car.

      I’ve brought my first car a while ago it’s a 2008 Toyota Aurion sportivo zr6 it has 215xxx kms I’ve been wanting to modify it as it is tidy but I’m unsure if I should since the car is this old and I have had to replace the oil cooler lines a month ago (my car dumped its oil on me) just unsure if they go good after a certain age. what I do want to do to it is. wheels lowering springs or coil overs stiffer sway bar exhaust tint all round after market head lights and tail lights (if any of you know decent ones could you shear a link as I’ve only been able to find some on eBay) if there is anything else that would make it look good like body kits if there are any would be nice to know. Thanks in advance IMG_0918.cr2

      2004 hzj79 surging/jolting

      Gday Ive got a problem with my 2004 hzj79 with 235,000kms with no turbo, ive takin it to a few places all have different answers. At 1400rpm just on light throttle it seems to be surging/jolting as if your on and off the accelerator. Ive recently had the head gasket, head, injectors, fuel filters and timming belt all done and is still happening after the works been done. Has anyone else had the same problem before or be able to point me in right direction? Cheers.

      Australian customers gullible ?

      Not sure if this thread is still active, but It's 2024 and nav is still a problem in my 2018 Prado. I paid for an update, but I haven't noticed any difference, maps are still out of date. I tend to use my phone, but I would prefer to use the existing screen. I think you're right, if enough of us complained or cared, maybe something would be done to improve this problem... we are customers and we paid well for it! Hopefully we are not a dumping ground for old tech!

      Gen 6 Cluster Backlighting Issues

      Hey guys, I'm having issues with the gauge cluster backlighting keep blowing fuses every time I turn on my lights. I have tried cleaning connections, replaced the lights and even removed the dimmer switch. Has anyone come across this issue at all?
