Overview
The x-generation (year-year) front HVJB isn't particularly useful on its own, but it does enable a number of other HV accessories as literally plug and play.
Connections
HV
There are 4 colour-coded HV plugs found along the top side of the unit (as oriented with the front label right side up) that correspond to particular HV systems. From left to right, they are:
- Grey: Battery Fluid Heater
- Blue: DC-DC Converter
- Orange: A/C Compressor
- Brown: PTC Cabin Heater
LV
The LV connector on the bottom left side is a 12-pin Molex MX150. Only 6 of the 12 pins are populated, as follows:
pin | function |
---|---|
4 | 12V |
5 | PWM in |
6 | STAT out |
10 | GND |
11 | HVIL in |
12 | HVIL out |
