Diagnostic Fault Information
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
| Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
| Powertrain High Speed GMLAN Serial Data (+) | 1 | U0100-U0299* | 1 | - |
| Powertrain High Speed GMLAN Serial Data (-) | 1 | U0100-U0299* | 1 | - |
| Ground (DLC, terminal 5) | - | 1 | - | - |
| * No communications with one or more Powertrain High Speed GMLAN modules. An open in only one Powertrain High Speed GMLAN serial data circuit may allow degraded communication between the modules. An open between the data link connector (DLC) and the first splice will only effect the communication with the scan tool. The vehicle modules will still communicate. 1. No communication with any Powertrain High Speed GMLAN module |
