I have a 2003 gh430 with 109,411 miles. I bought the aisin timg belt kit. Replaced the timing belt, drive belt, water pump & gasket, o-rings,thermostat & gasket, camshaft seals, idler 1 & 2, hydraulic tensioner, NGK IX Iridium spark plugs, covers for the pedals except gas pedal cause it was to long. Now the vsc light & check engine light is on.

 

Disconnect battery for 30 min and then reconnect.

ANYTIME you see VSC/Check Engine light on and don't have a clear reason why, force it to be cleared. Seen it too many times set for no legit reason.

I did my timing belt and got the drivers side (left) cam off by 1 tooth and didn't realize it till I started it. It came up with a code, but no VSC/CE light. I had to go back in and fix, not a real big deal.

Hopefully all is ok, should be.

 

Did you start the car with the wheels off the ground? That set off the lights in mine once. I put it down, cleared the codes, and was fine.

 

The wheels were on the ground and i will be buying a new battery so i will not connect it for 45 minutes to see if that does anything

 

The vacuum hose was knocked off. Jus had to reattach it. Check engine light oooooooooooooooff
