Jeep Liberty OCM calibration

I don't know about the MK 908 but both of my Autel scanners (Ultra and Elite) have this function. After reading the codes is there a “special functions” key?

I do have a special functions key, but it only lists an OCM verification test and this appears to test the calibration and it comes back as “failed”

This is not a DRB III vehicle. By 2008 all FCA vehicles were CAN.

Thanks for the clarification.

This is a wiTECH vehicle not a DRB vehicle, also need a set of OCM calibration weights

Would be nice to actually know what these weight. Could make these fairly easily. Cheaper than paying several hundred dollars to manufacturer for something your likely to use maybe a handful of times. Assuming you don't scare away the customer with the price of the OCM mat/module.

Find the weight of a rear facing infant seat with child in it, 6 year old child and the 1/5th percentile female. That is what the seat weight calibrations are based on.

Well this is pretty subjective. Rear facing child seats don't all weight the same. The same could be said about children and women. So it is hard to determine what manufacturers consider each weight to be, without them telling you directly.

like I said there is a calibrated set that FCA uses, what they based the seat weights off all averages and for the female it is the average weight of 1/5th of the US female population which is approx. when the weights came out of 115#

you can spend $800 plus on the weight set or, you can go to Academy or Walmart and pick up some free weights. There are 4 stages on a Mercedes and Chrysler Dailmer only used 3 of the 4 stages. The weights are as follows: Mercedes - Stage 1 - zero weights; Stage 2 - 38. lbs (average weight of an infant and infant car seat); Stage 3 - 60 lbs (average weight of a six year old child); Stage 4 - 98.5…

$800 but do it right or don’t do it at all. This is a air Bag related calibration. IMO don’t do it. It would be the same as doing a radar calibration with some Tim foil and a stick. May get the light off but it ain’t right

Warren, you‘re in Lynchburg. I do CVille. Working my way your direction. We will have OEM targets and scan tools. But, price, not sure how we will compare. Service can’t be beat

This is what my scanner screen looks like. That button will take you thru the steps to calibrate the occupancy sensor.

its a 3 step process involving OCM calibration weights.

Thanks Mike. I may need to see if there is an update for my tool that will add this function.

No problem David, once you do the update you will need weights for the passenger seat. The scanner will tell what weight to use. I have free weights in my office that I use. I always put a mat down on the seat for 2 reasons, first is to protect the seat, the other is to distribute the weight.

Was looking for the weights but found a listing on ebay for a set ebay​.​com/itm…

The ORC verification test is the procedure for B1BA8. The B223D is just an SRS code indicating a code in the ORC. As others have said, you need the correct weights to perform this verification. All of this is laid out clearly in service information.

Great to hear you got it sorted…
