Diagnostic Fault Information
| Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
| Object Detection High Speed GMLAN Serial Data (+) | U0075 | U0075, U0100-U02FF* | U0075 | - |
| Object Detection High Speed GMLAN Serial Data (-) | U0075 | U0075, U0100-U02FF* | U0075 | - |
| Ground (DLC, terminal 5) | - | 1 | - | - |
| * An open between the data link connector (DLC) and the first splice/device will only affect the communication with the scan tool. The devices will still communicate. An open in only one object detection high speed GMLAN serial data circuit may allow degraded communication between the devices. 1. No communication with any object detection high speed GMLAN device. |
