Diagnostic Fault Information
| Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
| Chassis High Speed GMLAN Serial Data (+) | 1 | U0100 - U02FF* | 1 | - |
| Chassis High Speed GMLAN Serial Data (-) | 1 | U0100 - U02FF* | 1 | - |
| Ground (X84 Data Link Connector terminal 5) | - | 1 | - | - |
| * No communications with one or more chassis high speed GMLAN devices. An open in only one chassis high speed GMLAN serial data circuit may allow degraded communication between the devices. An open between the X84 Data Link Connector (DLC) and the first splice/device will only affect the communication with the scan tool. The devices will still communicate. 1. No communication with any chassis high speed GMLAN device. |
