We also got our hands on a virgin EDC15 ECU at a reasonable price and I want to read the 24C04 chip on it before we adapt it, but the reader I have doesn't want to read it in circuit. Any additional advice on checking if CAN is functioning properly? We're attempting to fire the car on a 2003 ECU that I've Immo-Off'd (De-Immo'd? Whatever.) I am no longer seeing Unauthorized ECU in my list of DTCs so I think we've got a harness or sensor issue preventing the start. Wiring is OK, sensor checks out OK in terms of resistance spec, but signal isn't getting to ECU. G68 Engine Speed Sensor is not communicating. We've been digging through a myriad of electrical issues and we're down to one. The cluster shows this DTC:ĬAN should be connected correctly as the chassis and donor harness/ecu are both 2003. I have checked my diagrams and connections over and over. Is CAN-bus connected correctly? System not OK refers to cluster not being able to communicate with ecu. I can provide any additional information if necessary. One theory that's been offered so far is the Diesel ECU will not adapter to a gasser cluster and to copy my immo information from my gasser cluster to my diesel one, but I'm not entire sure what I need to transfer? Just VIN/IMMO-ID/Checksums?Īny advice is appreciated. We'd like to retain immo functionality on this vehicle. Can the 24C04 IMMO chip be read via OBD or bench on the EDC15? Do I need to get information out of the ME7.5 ECU that I haven't already obtained? Not sure where to go from here. I do need to find a clip that's reliable (Pomona 5250 is on the way) to make this easier in the future. My clip was not cooperating, but it read fine off the board. I had to desolder the 24C04 from the EDC15 ECU to read it.
#VAG TACHO 2.5 MANUAL SOFTWARE#
I've got a wide variety of tools at my disposal: VCDS HEX-CAN-USB, VAG TACHO 2.5 & 3.01, An EPROM reader capable of reading 24C04/95040 chips (and others), and probably could get NefMoto's software working with my VCDS cable if necessary. We've also got an FIS cluster that needs to get swapped in, but I presume I cannot swap a cluster and an ECU at the same time due to the need to pass the Immo-ID from Cluster to ECU and then from ECU back to new cluster in multi steps. Here's the VIN and IMMO-ID from the original 1.8T cluster (VIN/IMMO-ID hidden): Here's the VIN and IMMO-ID from the donor 2003 ALH ECU: The Engine ECU doesn't have any errors pertaining to immobilizer or instruments. I do have a few error codes due to some of the items not being swapped or wired yet, but the only pertinent one in the instruments is Unauthorized Engine ECU. It acts like it doesn't accept this as the "previous" ECU when attempting the adaptation. The SKC 2995 (02995 above) is the SKC pulled out of the cluster that was paired with the original 1.8T ECU.

Also the new VIN information does not transfer to the new ECU. (Login procedure does not produce an error nor a disconnect from VCDS.) With the original 2003 1.8T cluster and 2003 ALH ECU and following Ross Tech's Instructions I get a "System NOT OK" error when entering the old SKC into adaptation channel 50 when I'm supposed to get VIN and IMMO-ID information. As we don't have the cluster from the 2003 ALH the donor ECU came out of I retrieved the SKC from the 24C04 EPROM in the ECU and confirmed I can log into the ECU. I retrieved the SKC out of the original 1.8T cluster, which I presume matches the SKC in the ECU that was working with the car.
#VAG TACHO 2.5 MANUAL MANUAL#
The Auto to Manual conversions have been done to the harness. The ALH itself is from an '00, but we've got a '03 Auto TDI ECU and harness. We've got a 2003 1.8T Jetta GLX Wagon that's getting an ALH with a DRW 6-speed. Seems like my 2nd post here is going to be a long one and a doozie.
