MPVI4 Face Plate Description
Below outlines the legacy features on the face plate of the MPVI4, with a detailed description of each LED RGB (red, green, and blue) and bluetooth status icon.
| 1. | MPVI4 Face Plate |
| 2. | HPTNET Screw on Connector |
| 3. | Status LED Icon |
| 4. | Bluetooth Low Energy (BLE) LED |
| 5. | WiFi LED |
| 6. | Standalone Data Log & Bluetooth Button |
| 7. | USB-C |
CAUTION: When over-voltage is detected , the MPVI4 Status LED will become solid red and will remain solid red until voltage drops below 15.5v, then it will go back to solid green. Operating the MPVI4 with voltage over 15.5v can cause damage to the MPVI4.
NOTE: When an overcurrent event is detected, the firmware attempts recovery by cycling the bus OFF and ON up to three times, checking if the current drops below the threshold. If any attempt succeeds, normal operation resumes. However, if all three attempts fail and the current remains high, the LED turns solid red. At that point, only a power cycle or OBD reset will allow the MPVI4 to recover.
