when car shuts off, how many parking light flashes were there?

i am not sure which brain compustar use, try this method to lean tach first.
start your car using key, let it idle for a bit, hold brake pedal and press II button for 2~3sec.
if you hear 1 flash, brain learned tach.

if that is not doing anything, brain must be older version, you will have to locate brain and there will be tach learning button on the side of brain, start engine, let it idle for a bit and press tach learning button. you will see 1 parking light flash.

but before trying this, when car shuts off, count number of flashes and post it here, that will tell me what exactly is not working correct.

it could be as simple as rusted hood pin.
