hi, i have customer that back to me with aways immo light and nonworking car, after throttle driver was changed in sim22 and i gave him a car working ok. Now when i switch ignition ON fuel pump clicking sound(some times stay for while like normal but alomost of the time only click one time) and immo light stay for 2-3 min and then gone. Ecu has 11 error throtle position,app position error, CKP, Ignition coil error and etc. IN IPC i have one error only invalid data from engine coolant sensor(maybe sended from ecu ?)

what tried virgineze ecu and pats coded again, for a while PATS STATUS is ACCEPTED, but when restart ignition again lamp stay and car dont crank...

Help guys, what i can do ? ecu faulty ?

im not sure that my ecu is faulty, cuz that same car last year came to me with flashing EAC and clicking sound from fuse box. was faulty wiring below battery.... but now i check all wiring that ecu care about it. all fine but theese all error for TPS APP CKP ignition coil why apear ? i think theese error show when PCM is not sync with IPC, im right ? i think that cuz try another ecu pluged not coded same 11 errors. thats normal ?

With ECU off it's easy enough to check power supplies to a sim22. Load them up to make sure current is strong enough. Earth EC relay control and do same checks on EC output. Scope CAN lines to make sure no distortion. If all looks ok then ECU kits are cheap enough to buy as a guess. Clocks and ECUs are common for failing intermittently in these nails. Sometimes its just easier to swap all the modules to see if it's that. These things are that crap you will use the unused stuff you buy pretty rapidly anyway.
