| Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
| High Speed GMLAN Serial Data (+) | 1 | U0100-U02FF* | 1 | - |
| High Speed GMLAN Serial Data (-) | 1 | U0100-U02FF* | 1 | - |
| Ground (DLC, terminal 5) | - | 1 | - | - |
| * No communications with one or more high speed GMLAN modules. An open in only one high speed GMLAN serial data circuit may allow degraded communication between the control 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 high speed GMLAN module |
