Where can I find the wiring diagram for this Chevy Colorado 2007 for the Speedometer. I bought this Truck to this local Car Dealer with Speedometer doesn't function at all. I want to try to see what...


Your speedometer is controlled by your computer network. The vehicle speed sensor (VSS) sends a signal to the Body Control Module (BCM) which then relays the speed sensor data via the UART data lines to the Powertrain Control Module (PCM) and the Instrument Panel Cluster (IPC). To find out why your speedometer is not functioning, you must FIRST scan your ENTIRE computer network for possible fault codes. It is possible that either the VSS is defective or the BCM is not able to relay the information due to a communications fault, or the BCM is relaying the information and the IPC is unable to receive the information due to a communications fault, or the IPC itself is defective. Wiring diagrams will be of no use until you determine which parts of the network is receiving the information from the VSS and which parts are not. This will require the use of a scan tool that can not only read generic OBD fault codes, but also access and display codes and live data from the BCM, PCM and IPC.

How to remove the car stereo from 2007 Chevy Colorado


This is not hard but tricky because the trim plate around the radio has clips that hold the trim plate very tight.Use a plastic type flat tool or flat screw driver wraped with tape or a shop rag to avoid damage to the plastic trim and pry the trim panel around the radio loose. remove all elec connectors.Then remove the screws that hold the radio in place and remove all elec connectors.
