pkshin Posted May 1, 2005 Share Posted May 1, 2005 Hi Members, My Car: The Greates Car in history: LS400 91. With great help from this forum, I managed to replace TB & Water Pump a week ago. Everything else running OK excpet two. 1. Airbag light is on all the time. 2. Engin Check light is on all the time. Can any one tell me where the Airbag sensor is located? Somewhere around the radiator? And location of DLC1. Some info only indicated it is under the left hand side of the instrument panel, but I failed to locate it with my upper body squeezed into the narrow space. Many Thanks to all...

Many Thanks to all... ← Do you mean the obd1 diagnostic plug? Its under the hood, on top, right side of engine on my '90 LS. There is a good link somewhere on this site for reading the codes. Search "check engine light", and maybe you'll find it. Quote Link to comment Share on other sites More sharing options...

Search "check engine light", and maybe you'll find it. ← Thank you for your quick advice. I tried 'under the hood, on top, right side of engine(passenger side)' but under a plastice cover were two connectors, one was speed control agitator, and the other was round shape connector. Another huge bundle of wires wrapped in rubber cover were running thru the firewall to the glove compartment side. I checked underneath of the glove compartment and there were half a dozen connectors. How do you tell if a connector is the ODD1 diagnostic plug. I only saw a one dimensional drawing on this site. Please help. Quote Link to comment Share on other sites More sharing options...
RFeldes Posted May 2, 2005 Share Posted May 2, 2005 The plug is under the driver's side below the gas and trunk release. It's also where you jumper to remove the air bag light. Quote Link to comment Share on other sites More sharing options...
pkshin Posted May 2, 2005 Author Share Posted May 2, 2005 Thanks for short and clear information. I found it and read the code right away. The code read 13 = RPM SENSOR. That will be my next task to find out. I hope I just misplaced when I was put parts back. The engine shudders often during cruise. Hesitates when gear chaging from Rear to Drive. I hope any one can save my hassle. Many thanks to all. Quote Link to comment Share on other sites More sharing options...
