Diagnostic Fault Information
| Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
| High Voltage Energy Management High Speed GMLAN Serial Data (+) | 1 | U0100-U02FF* | 1 | - |
| High Voltage Energy Management High Speed GMLAN Serial Data (-) | 1 | U0100-U02FF* | 1 | - |
| Ground (auxiliary data connector terminal 5) | - | 1 | - | - |
| * No communications with one or more high voltage energy high speed GMLAN modules. An open in only one high voltage energy high speed GMLAN serial data circuit may allow degraded communication between the control modules. 1. Control modules on high voltage energy management high speed GMLAN bus will not communicate with each other on this bus. |
