Diagnostic Fault Information
| Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
| Powertrain High Speed GMLAN Serial Data (+) | 1 | U0100-U02FF* | 1 | - |
| Powertrain High Speed GMLAN Serial Data (-) | 1 | U0100-U02FF* | 1 | - |
| Ground (auxiliary data connector 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 control modules. 1. Control modules on powertrain high speed GMLAN bus will not communicate with each other on this bus. |
