Up till now, three different people (including myself) have tried to connect with different cables and systems. I am wondering if the ECU has been tampered with at some point or if the wiring has been damaged.
Then the only thing I can think of, is to measure if the wires from the ECU to the 3-pin diagnostic plug are ok. Since the manual method works, I still think the ECU is ok, but I don't know how the manual test system is working.
I have found out that the ecu was reprogrammed to an earlier version car as the immobiliser was removed owing to problems. Would this cause an issue with the twin wire plug and there not being any signals being sent to it?
I have a couple of issues- 1. The ECU not communicating via the plug 2. A recurrent fault - 1244. We have changed the EGR solenoid twice but the fault just returns after some poor running
I saw on another forum that a car had a similar problem and that the timing was out by one notch. same fault code 1244. The symptom were as 2 above. Also, the car doesn't seem to have the full power you would expect.
Has anyone else heard of the timing issue being a problem?
Hi Alfan Thank you. I managed to get the ECU pin connector details from the ECU testing company and hope that now we can establish what is going on. Interestingly there is an anomaly in the diagnostic wire colours between what is on the car and what the wiring diagram details. Is it possible that as my car is one of the last, the wiring was changed?
We have not checked the timing yet as Glenn wants to make sure the ECU issue is cleared first.
