rmscaldwell Posted October 2, 2007 Report Share Posted October 2, 2007 Re: 02 STS According to my dealer's service folks, the LF suspension sensor failed. They want approximately $700.00 to fix. 1) is this a safety issue? (the dealership wouldn't answer) 2) is this a fair price? 3) any literature on this?

Bruce Nunnally Posted October 2, 2007 Report Share Posted October 2, 2007 The Electronic Suspension Control (ESC) system consists of the following components: ESC module (3) Four dampers contained in the 2 front struts (5 and 6) and the 2 rear shock absorbers (1 and 9) Four positions sensors (2,4,7, and 8) ALC air compressor module (10) Damper relay (not shown) for RPO F45 only ELC relay (not shown) If the system detects that one of the sensors is not responding properly, it will set a diagnostic trouble code. You can check your DTC's using the procedure here: http://www.caddyinfo.com/readingcodes.html Let's assume the dealer read the codes and saw that you have a current DTC C0615, C0620, C0625 or C0630. Action Taken When the DTC Sets The ESC module will enter the Speed Dependent damping mode. Both Left and Right Normal Force outputs will be set to the default output states. The SERVICE SUSPENSION SYS message will be displayed. Speed dependent dampening mode means that in the absence of input from the LF Suspension sensor, the system is using the current vehicle speed to determine how soft or hard to command the struts/shocks to be. (1) Ideal would be to have input from the sensor, but the system attempts to fail gracefully to a safe condition. (2) You could get a quote from another Dealer for the same repair to compare. Or you can purchase a replacement sensor from rockauto.com or gmotors.com and replace it or have it replaced by a garage. The Repair instructions don't appear to be complex for the sensor replacement. (3) by Literature I assume you mean bulletins, recalls, tech info? I don't see any that refer to this specific issue.

rmscaldwell Posted October 3, 2007 Author Report Share Posted October 3, 2007 Thanks a Ton DTC C0615 is what they got. And I'm upset that the extended warranty I have doesn't cover this.

Bruce Nunnally Posted October 3, 2007 Report Share Posted October 3, 2007 Which extended warranty do you have on the Cadillac? The GMPP Major Guard should include coverage of this sensor: (from gmpponline.com ): Major Guard covers parts and labor for the following list of components: [...]High Tech Components: OnStar; compass and thermometer; heads-up display; anti-theft alarms (factory installed); keyless entry (factory installed); ride control suspensions; traction control assembly; infrared display; heated seats; dual climate control; power sunroof. The shock absorbers would not be covered, as they are wear items; the sensors SHOULD be covered under the GMPP.

rmscaldwell Posted October 3, 2007 Author Report Share Posted October 3, 2007 Mine is called Value Guard and the folks at the 800 number denied coverage.

JimD Posted October 3, 2007 Report Share Posted October 3, 2007 Maybe the position sensor wire harness is damaged? Or the position sensor to chassis wire harness connector is loose or corroded? Or the connecting rod is hanging loose? If the position sensor has failed and must be replaced, the cost of parts can't be much more than the deductable even if the warranty company covered the cost.

Bruce Nunnally Posted October 3, 2007 Report Share Posted October 3, 2007 I tried browsing the rockauto.com parts list to find a LF position sensor cost with no joy.

Bruce Nunnally Posted October 3, 2007 Report Share Posted October 3, 2007 Ah. http://www.gmpartsdirect.com under 02 Seville, then Electrical, Ride control components, Position Sensor, Front shows the part as MSRP $215 discount price $121 + S&H. Be careful how much the S&H is. I would email http://www.gmotors.com and ask them to research the part number and quote the part shipped to you. It looks like it is a simple matter to replace the sensor. I am uncertain why the dealer suggests that this is a $700 problem; even at $215 for the sensor and 1 hour of labor it seems $700 is x2 what the cost should be. Can you ask them to explain how much labor and what parts are required?

rmscaldwell Posted October 3, 2007 Author Report Share Posted October 3, 2007 Thanks for your insight. I'm going to live with the idiot message for a while and then fight with Caddy.
