TOD check light flashing

[etlsport]

good luck on your drive! sorry that nobody really had any definite answers for you, TOD failure isnt very common so there arent any real documented fixes for it, other than making sure tires are the same size and inflation and that fluid is full and connectors are tight

Not sure if this will help you but I had a problem with a buzzing sound coming from under my passenger seat. I took out the seat and pulled up the rug to find a relay/transformer making a buzzing sound. When I removed it the TOD CHECK light came on. The relay looks like this:

The specs are: 40A/30A 12VDC

Not sure if this would work but replacing it may do the trick. I found them on ebay really cheap ($10).

as far as i remember there are no relays under the passenger seat normally, so the one thats buzzing is more than likely added on for whatever reason.. sounds like they tapped into the wiring down there which is almost all for the TOD.. probably spliced into a blue wire? wonder if they thought that was the remote turn on from the head unit.... that would be my guess because many people "disconnect" their tod by putting an switch on that blue wire and when its turned off the check light flashes from my understanding............... relays usually make terrible sounds if they are wired improperly

Interesting, the unit has the ISUZU logo on it which made me think it was standard.

Interesting, the preamp unit under the passenger seat has the ISUZU logo on it which made me think it was standard. Where is the preamp and all relays usually located?

its possible its factory.. i dont remember seeing any relays down there though, most of the relays are located in the engine bay and behind the kickplates in the footwells of both passenger and drivers side (most in the drivers side, but i think there are one or two on the passenger side)

you could start off by replacing it and see if that helps since its an inexpensive part, i picked a couple up at a local car alarm installer for like 5 bucks each

Thanks, I'll get photos up later tomorrow...
