[QUOTE="OldmanBM, post: 738294, member: 4576"] Sensor if I am not mistaken is under passenger seat . Its in a form of a net.... i think . Difficult to find new, if available also very expensive , around RM800+. The other problem is you would have to strip down the leather seat to the bone to replace the pressure mat, which is under the front passenger seat.This will incur additional cost. There is also a remote probability that the airbag warning ( we sometimes call it Pregnant Lady light) is from defective seat belt tensioner. A quick check using diagnostic tool/ inpa will tell. Your options: 1) Change seat pressure sensor / new or used , 2) Cheat the seat sensor to tell the car there is either someone on the seat 24X7 or nobody 24X7 - which latter will disengage the airbag ( the 1st option will engage your airbag). This cheat uses certain resistor diode which is added to the seat sensor circuit. Both Option has good and bad. Pls consider safety also when making decision. My 2 cents , good luck. [/QUOTE]
