Retail Posted on August 25, 2010 In 2009, I was working on a 2000 Silverado with a technician from northern Minnesota. The Silverado had an anti-lock brake light on with a code C0235 stored. The technician said that the chart indicated it was a rear speed sensor code, but the truck doesn’t have rear speed sensors. For the most part, there are two different ways modules share information: 1) to send the information to another module by way of data line, and It will be very helpful to skim through the flow chart to try and determine which way the voltage is traveling. Be sure the flow chart is not asking you to check for voltage, only to have the next line say, “Repair the wire shorted to voltage.” In the case of the Silverado, the PCM should put out about 10.0 volts to the EBCM. A quick voltage test at the EBCM revealed no voltage on the yellow/black wire. Next, the voltage at the PCM was tested and found to be 10.0 volts. Great -- a broken wire or bad connection. If there had been no voltage at the PCM as well, we would have tested the yellow/black wire for a short to ground or to another wire before condemning the PCM. Most of today’s cars and trucks are using shared information in as many systems as possible. This greatly reduces the cost and complexity of extra sensors, connections and miles of wiring, not to mention it can help shorten diagnostic time like it did on this Silverado. Seeing that the speedometer worked meant not having to check the speed sensor, reluctor, or wires and connections to the PCM. We’ll be sure to keep sharing the latest information with you and as you share information back with us, it closes the loop to help pinpoint where the problem spots are on each vehicle.
