how does safe mode works
hello everyone !
does anyone now how the safe mode works on the tbi motor ?
i own a 2010 brera tbi and got a check engine message the car missfires and its about to stall
when at safe mode i pulled out all coils No1 and No4 there was no difference in the engine's sound or fuction (No2 and No3 coils were fine) so i assume i have to change the coils (1,4).
But then after restarting the engine the safe mode was gone everything worked fine , thats why i ask how does the safe mode works , does it cut the power to the coils for protection ? does it cut ignition ? anything else ?
thanks in advance
