Question about MTS
'16 4runner Trail Premium

My Multi Terrain System is not engaging, trying for the first time.

Tried in 4Hi & 4Lo
No error codes or warning lights on Dash.
Though at times I do get an air bag light because it's an accidental car but even after clearing all codes nothing shows up.

When I press the On button on the MTS knob all the lights flash and they go away, but when I rotate the knob to select a terrain do not get anything or able to select.

However, ATRAC, rear diff lock, crawl control system (left knob), traction control works perfectly fine.

Tried Zero Point Calibration, but still not engaging through TechStream. only error code is B2661 for D-seat sw, my driver seat lift and lumbar isn't working.
