Diagnostic Fault Information
| Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
| Low Speed GMLAN Serial Data | 1 | U0100-U0299* | 1 | - |
| Ground (DLC, terminal 5) | - | 1* | - | - |
| * An open between the data link connector serial data circuit terminal 1 or ground circuit terminal 5 and the BCM circuit will only effect the communication with the scan tool. 1. No communication on any low speed GMLAN module |
