p00rmansp0rsche Posted October 6 Share Posted October 6 Greetings to everybody I have scheduled my vehicle for a MOT this Friday and have just recalled an occasional problem associated with an error number that, if activated, results in an automatic failure. The problem is sporadic and occurs just when weight is applied to the passenger seat. The resolution is not expedient if the occupancy sensor is defective. I find it quite absurd to only wish that the tester refrains from occupying the passenger seat. 😂 I have seen several opinions about these bypass emulators; does anybody possess knowledge with them?

CyberNinja Posted October 6 Share Posted October 6 They should not occupy the seat; instead, they should test the belt to ensure it stretches, retracts, and secures properly. I previously used an emulator and felt that adequately resolved my problem. Quote Link to comment Share on other sites More sharing options...
p00rmansp0rsche Posted October 6 Author Share Posted October 6 I am now contemplating this matter. What is the reason for the illumination of the airbag light due to a defective occupancy sensor? Upon analysing this mentally: The occupancy sensor only informs the ECU about the deployment of the airbag and the need to check for the seat belt clasp, correct? If the sensor is defective, the vehicle likely perceives the seat as unoccupied. What is the reason for the lights to stay illuminated intermittently when a load is applied and then removed?

SkippyTom Posted October 6 Share Posted October 6 The sensor deactivates the airbag when a child seat is installed (indicating insufficient weight for an adult) and also while the seat is unoccupied, hence preventing the need for airbag repairs post-collision and reducing insurance costs.

SkippyTom Posted October 6 Share Posted October 6 The ECU recognises the sensor malfunction and will default to deploying the airbag during a collision as a precaution. The emulator simulates occupancy in the ECU, causing the airbags to deploy even when the seat is unoccupied. Quote Link to comment Share on other sites More sharing options...
p00rmansp0rsche Posted October 6 Author Share Posted October 6 Understood, thank you. For the sum of £23, I may just get the emulator. I have only adults seated in the front, and if a collision occurs that is sufficient to deploy the airbag, I am certain that my vehicle would be deemed a total loss regardless.

KissezFun Posted October 6 Share Posted October 6 Although uncommon, a tester may accompany an individual in a continuous 4x4 vehicle throughout the braking test on the road to record the data. He will only fasten the seatbelt and apply a firm tug, but he will not occupy the automobile while doing so. Quote Link to comment Share on other sites More sharing options...
