R061, R062 - SIR Indicator Circuit Failure
 

Hey all -

The codes R061 & R062 (SIR Indicator Circuit & Redundant SIR Indicator Circuit Failure) have appeared in conjunction with these symptoms: Gas gauge reads E, Voltmeter reads 0.0, chiming constantly when lights are on, Twilight Sentinel not functioning, cruise control not functioning, remote fuel door/trunk release not functioning.

My troubles began when my alternator began to fail a few weeks ago, I have a feeling that the low voltage condition might have caused one of these sensors to heat up and blow out breaking the circuit... all fuses check out OK.

I did some searching, and I found two other threads on other forums with the same exact symptoms with the same codes thrown, I attempted to get in touch with these people as nobody had found a workable solution for them but the threads are a number of years old already and I got no response... The threads I found were here (94 DeVille problems) and here (R061,r062,gas Gage,no Volt,chime).

Does anybody have an insight on where to begin on this problem? Car is a 1995 Cadillac Sedan DeVille, 4.9L.

Thanks in advance

Traced it all to a faulty fuse (Ign 1) in the engine comp. Problem solved
