Recently my C5 began throwing a code which indicated that the RF Wheel Speed Sensor was going bad.

According to this list http://www.stengel.net/diccodes.htm ....


28-TCS - Traction Control System...

C1225 RF Excessive Wheel Speed Variation
C1226 LF Excessive Wheel Speed Variation
C1227 LR Excessive Wheel Speed Variation
C1228 RR Excessive Wheel Speed Variation

the code I recieved 28-TCS C1225 is for the RF wheel. Now here's the thing - Kevin's resource - Mitchell lists the codes just the opposite. C1225 = LF and C1226 = RF.

So which is it??? ;help

I would fly this one by C4/C5 specialist. He seems to know when certain codes are caused by other things than what the DIC says.
I had the LR speed variation code come up when the problem was actually caused by a wire chafing on the fuel rail and set off BCM door codes and a bunch of other wierd stuff that never showed up agian.

Thanks Jim.

We replaced the RF wheel speed sensor and cleared the code. Then, during my drive to TN, it threw the same code again. Cleared it... and all was fine until it happened again on the trip home.

Now we're thinking that the LF sensor is actually the problem and the codes listed may be backward. ;shrug Either way I'm taking her in tomorrow for Kevin and Chris to check things out.

If I remember correctly, a tire out of balance, a loose connector, water in the connector, pinched wire, or a bad wheel bearing can cause this code to display.
