Lift gate/glass switches

[jhilario72]

I have the Rear Access Open error message. How do I test the 3 possible switches in the back (1 glass lift gate, 2 lift gate)? And what would I test? Is there a continuity test or something electrical to measure?

Thanks,
Joe

Do you have a good bi-directional scanner?

No I don't. If I can borrow one, what commands would I send? Thanks
