just a quick question. I have a customer with a ZS that has come in with no hazards. As it is an 04MY that was easy. Momentary switches weren't enabled via ZCS codes. However, when he sent me the current configuration, it was all wrong totally. according to the current ZCS the car is a diesel!It's not, it is a 1.8 petrol. Now, he has since told be there are at least two spare scu's laying in the customers car so someone may have been "playing".
Now for the strange bit. When I sent him the new ZCS codes they went in, hazards work, car runs as sweet as a nut. However, The SA string data is not being retained. GM and VN no problem. So without the SA string being retained T4 (Testbook version 4.Computer Diagnostic System) is showing 12 fault codes continually.
The question is.....which ecu holds the master data for the SA string.
Engine ecu, SCU or SRS (Supplementary Restraint System) ecu??
Any help or advise gratefully received.
