Year of Manufacture *: 2003
Engine Size and Code *: 1.9 AVF
( Optional ) Scanner Used: KTS
I cant get comms with Engine control but can get into everything else. I have all my powers and grounds where I should have and the Main relay is OK.
I have fault codes throughout the other controllers for no comms with engine ECU
I have 60 ohms across the CAN at the engine ECU and scoping it gives the correct 2.5v signal on both can hi and lo but the signal is intermittant. I will get flatline for several seconds and then some signal before flatline again.
At 940+vat for an ECU I need to be sure !!
Anyone ever replaced one ? Are there any tests I have missed ?
