According to the displayed fault on the app it just says that the resistance is too high on the front tensioner circuit, not which side.
It's not possible for it to read each one unfortunately as they're linked.
It's one of the bugbears with the SRS system when it comes up with that error it could be one side or the other or both
With all the other modules it correctly identifies which one is causing the problem.
Wish they would have designed the front pre-tensioners the same way, it would have saved me a lot of time over the years.
