Flashing overdrive light

[simonc]

I've had a non-turbo, automatic Supra for 3 years. The overdrive light has recently started flashing whilst driving with the Overdrive switched off. I've take it to a few garages, but no-one seems to know what's causing it.

Has anybody got any ideas please?

I had a quick search and came up with the following: -

Find the ECU error code (http://www.mkiv.com/techarticles/engine_codes/obd1_codes.html)
Maybe an ECU Reset (http://www.mkiv.com/techarticles/ecu_reset/ecu_reset.jpg)
