Hey everybody. I just got my eg6 firewall converted to rhd and it has a check engine that comes on only if I drive for a while but if I just drive it up and down the street it doesen't come on. How would I check the ecu code for the rhd because I know its different than the lhd, and how would I probe it to check the code? Pics would be greatly appreciated. Thanks.

 

find the ecu. there should be the service check port next to the ecu. if for some reason it wasn't wired in when you did the rhd firewall conversion, and ur car is obd1, find connector "d" on the ecu



jump the wire at pin 4 with pin 21 on connector "D"
turn the car on to the "on" position.
this should cause your cel light to blink, and read the code.
