Diagnostic Fault Information
WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
| 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 (X84 Data Link Connector terminal 5) | - | 1 | - | - |
| * No communications with one or more high speed GMLAN devices. An open in only one 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 high speed GMLAN device |
