Trying to communicate with a VZ on ALDL using J2534dotnet.dll.
Problem im having is after receiving heartbeat next write command (disable chatter or table read) is taking to long to send.
Sometimes i get lucky and it sends straight away and it works.
Cant find any info on MDI and ALDL anywhere.
Has anyone been able to make a stable connection on ALDL using J2534?
Thanks
Matt

Re: J2534 ALDL Help Needed
ALDL was something that was not documented at all by any company. I even spoke to the engineers over at drewtech and the guys that made their ALDL implementation no longer worked there, so there are no 'examples' for how it worked or what to do.mattyjf01 wrote:Trying to communicate with a VZ on ALDL using J2534dotnet.dll.

From what I have found, most places do not use the j2534 for ALDL, they use the DPDU api, which is what the tech2win uses for the MDI. I believe they did this intentionally cause the J2534 API designed for them was absolutely trash.
Different firmware's of the MDI resulted in different behavior of the tool for j2534 ALDL, some would do a few frames, others would do none.

Re: J2534 ALDL Help Needed
Found a work around.
Lowered all the timeouts and ran the routine in a loop until a heartbeat and silence BCM was successful
Wont know 100% until i can test it in a car.
Bench setup is only a BCM, PIM and ECU.

Didn't think there were any aldl timing specific parameters to adjust, at least not mentioned in the j2534-2 standard? Or are you just meaning your looking through a write and read message command until it goes through?

Yes, I would not be surprised if there was no collision detection and retry in ALDL and correctly silencing the bus is the ticket, as with other interfaces.
