Just a quick question,

Will my Autel MS 908 calibrate the lift gate?

What is the procedure to calibrate the automatic liftgate?

I'm working on 2008 Tahoe automatic lift gate.

Some hack N split mechanic did a poor job on it now it's my turn.

The bad.

Motor assembly disassembled in left quarter panel. ( parts missing and laying on floor behind panel).

New motor assembly installed, and found latch with broken plastic gears inside, replacement is on the way.

It looks like the other guy just broke stuff and removed the gear from the motor and broke the connector, good thing new motor came with a complete harness.

The latch probably just broke on its own. ( plastic gears).

Current problem.

I'm not finding enough information about the calibration except to use a Tech 2 but I do not have one.
TECH 2 INSTRUCTION, toggle to lift gate module, select setup, select LGM open/close test, follow on screen prompts.

I have an Autel MS 908 pro and an older 2012 Genisys ( Matco Determinator).

Thank you

That will likely need the Tech II. I don't know of aftermarket tools that support that level.

Thank you, I'll have to wait because my brother has my Autel but the replacement latch is working with the key fob and the button on the handle. The close button on the lift gate works intermittently.
I have a Launch Torque 3 coming soon.

Just a quick update, I will probably get one of my scantools back soon but gate is working A ok!
