Signal Specification (2009-2011)
WARNING: This page is about a different variant/trim than selected.
General
All the values given below are between the terminals stated in column 1 and terminal #A8 in column 2 (power ground). This applies unless otherwise indicated in brackets.
NOTE:
It is important to connect the breakout box and check the ground connections before measuring.
| U= | DC voltage in volts (V) | Ulow = | Voltage approximately 0 V |
| Ubat = | Battery voltage (V) |
