Introduction
More and more vehicles are now using Ethernet networks, also known as DoIP (“Diagnostics over Internet Protocol”), which allow vehicle systems to transmit data at much faster speeds compared to CAN networks. Certain vehicle diagnostics are primarily available via DoIP rather than traditional CAN networks.
- HRN-BM16T22 has the 2-pin Molex connector for Ethernet (pins 3 and 11) connected by default.
- HRN-BM16T2-LD and HRN-XBM16K2-LD has a 4-pin Molex connector labeled C3/C5 (pins 3 and 11) connected by default.
- HRN-BM16T2-HD and HRN-XBM16K2-HD has a 4-pin Molex connector (pins 3 and 11) connected by default.
*This must be disconnected for any vehicles that require an Ethernet bypass to ensure that scanning tools and other equipment are not affected.

For an Ethernet bypass, disconnect the 2-pin Molex connectors attached to the 16-pin T-harness (HRN-BM16T22)
-
Failure to disconnect the Molex connector may cause issues when performing non-Geotab software updates.
-
-
-
For an Ethernet bypass, disconnect the C3/C5 - 4-pin Molex connector attached to the 16-pin T-harness (HRN-BM16K2-LD or HRN-XBM16K2-LD).
-
Failure to disconnect the Molex connector may cause issues when performing non-Geotab software updates.
-
-
-
For an Ethernet bypass, disconnect the 4-pin Molex connectors attached to the 16-pin T-harness (HRN-BM16T2-HD or HRN-XBM16T2-HD)
-
Failure to disconnect the Molex connector may cause issues when performing non-Geotab software updates.

WARNING! All in-vehicle devices and related cabling must be securely fastened and kept clear of all vehicle controls, including gas, brake and clutch pedals. To ensure all devices and cabling remain securely attached, inspect devices and cabling on a regular basis.
-
Loose cabling or devices may impede the use of vehicle controls, resulting in unanticipated acceleration, braking, or other loss of vehicle control, which could lead to death or serious personal injury. Upon sudden acceleration or deceleration, improperly fastened, in-vehicle devices may detach and impact operators, which may cause injury.
