Additional complication

[Sagitar]

I came across this quote on a Toyota site:-

 

"The zero point calibration of the yaw rate and deceleration sensors is supposed to performed after front toe-in is adjusted. This requires the Toyota diagnostic laptop, so a visit to the Toyota dealer service dept is required".

 

I assume that the sensors mentioned are part of the vehicle stability systems and since many modern vehicles have such systems, I further assume that the requirement to calibrate such sensors is general.

 

Can these calibrations be performed as part of the WIM geometry measurement and adjustment, or does it mean that every adjustment of toe-in requires a subsequent calibration check at a dealer?

 

I guess the matter must be quite serious in cases where significant adjustment is done to correct geometrical positional errors caused by pot-holes etc?

Thanks Tony - should have known you would be on the ball.

 

But watching the video, it seems to deal only with what Toyota call the yaw-rate sensor and they also mention the need to calibrate a deceleration sensor?

 

It's difficult to see how we are going to keep up with the ever increasing use of dynamic telemetry devices. It seems to predicate the use of special equipment related to specific vehicles and takes us back into the hands of non-specialist staff at the service facilities of manufacturers.

I think it's a case of "keeping up" when the real world requires it?..... Hows this example for ironic, the steering position sensor "MUST!!" be reset after an alignment or all manner of lights will flag warnings on the dash........ So how come no warnings were flagged when the alignment was displaced
