IT IS THE ECU BUZZING FOR 5 MINUTES AND THEN CLICKING
should i reset the ecu if show tell me in what order to do things with disconnecting the battery
Expert:  Chris (aka-Moose) replied 1 year ago.

We can try a ECU reset first but I just do not believe this is going to work. Disconnect the battery cables and hold them together for one minute then reconnect. This will reset all modules. Let me know those results prior to me getting into wire testing at the ECU connector.

it sucks got billed 25 bucks and still no answer
Expert:  Chris (aka-Moose) replied 1 year ago.

So I assume the reset you asked how to do failed to resolve the issue?

Expert:  Chris (aka-Moose) replied 1 year ago.

The transmission control module and the electronic control module are mounted together at the right front of the engine compartment. Is that what you were asking about?
