CO615 Code - Advice Please
I was hoping someone may help me on this code. C0615 - I know that is a faulty LF Suspension Position Sensor Circuit ESC.
I have been able to clear code from DIY but it has popped up a 2nd time with the message "Service Ride Control" after 50 miles. By
the way that is the only message I am getting and clears out when I reset (clear) code and shocks are not leaking. I found the Sensor sitting
on the wheel wall behind tire on drivers side. Connection looks clean and no debris noticed. 2004 Southern CA vehicle with 67,000 miles -
super clean. Has anyone replaced any of the Suspension Positioning sensors? Looks like a simple swap out - I know their are four of them
for each shock. It looks like a replacement on a used one is around $126.00 - new $250.00. Are these Sensors known to fail?
Thank you for assistance.

I believe I may found the problem that threw this code. Last night I decided to disconnect the battery and do a Computer Reset. Also,
recently, I purchased a Motorola T505 Bluetooth device to utilize with my I phone in the Car. If you are not familiar with T505 - it actually sends
a frequency through the vehicles radio utilizing the radio speakers with connected. I was informed by a friend of mine who has been working on C5's and
other vettes for years. He informed me that some of these devices will interfere with the TPMS Wheel Sensors and possible other sensors that
communicate with the PCM in the vehicle. I did not start getting this code until I connected the T505 to my car radio. This morning I drove the
vehicle for 120 miles, stopped many times and restarted car during trip, good news the code has not resurfaced. Scan codes in my DIC - No Codes.
I hope that was the culprit. Just FYI if anyone plans to use this device in the future. Keeping my fingers crossed.

I wanted to follow up and share some good news. A week later and over 300 miles of driving, code has not resurfaced.
I believe the culprit was the Motorola T505 signal that interfered with the sensor. I also cleaned the sensor connector with
CRM Electronic Spray, suggested by a Forum Member. Keeping my fingers crossed.

I am getting the C0615 code sometimes. I clear it and may be many days before i get it again. To play MY MUSIC thru my car speakers, I plug into my cigarette lighter a CAR WIRELESS FM Transmitter (SYNCWIRE) that transmits FM signals to my car radio aerial. Then I have my music stored on a Digital Music Player (MP3 player) which using Bluetooth sends music signals to the SYNCWIRE which sends FM signals to my car aerial and the music then comes out of my car radio. Works great, but could this be the cause of getting that C0615 code? What was your experience with your problem.

My C5 seems to throw warnings (error codes) about various things from time to time but when I turn the car off, the next time I drive the car the warning has disappeared and may never show up again many months later or never at all.
Very tempermental electronics in these C5's in my experience.
