A common G20 (P10) problem, you start the car, you get check engine note, you turn the AC, and it’s not cold…..You put the gear selector on D or R , the damn G20 shakes then shuts down !!! I know you guys, you will say maybe the spark plugs ! or the throttle body !
But hey, don’t waste your time, it’s the Hammer Time, sorry, I mean it’s the ECU, you can send it to an electronics guy to reset it, or if you have enough money, you better buy a new one.

OBDII is an ECU Scanner (Reads the fault signals from your ECU - To save time locating the issue) |
This scenario happened with me twice, I did ECU reset, but sadly after 2 months my ECU died. I wanna buy a new one but I can’t find in U.A.E I found in E-bay, it’s cheap, but the shipping fees is extremely unfair. I must check all the electronics heads & freaks in U.A.E =(
Note: Before buying a new one, make sure the that the product number matches your old one, mine is A11-C71 CA8
