Test
Do the platform lights blink
when the platform emergen-
cy stop switch is pulled?
Measured RESISTANCE be-
tween X060.3 Red wire and
X060.4 Black = 60Ω?
Measured RESISTANCE be-
tween X054.1.soc and
X054.3.soc = 120Ω?
Measured RESISTANCE be-
tween X057.A.pin and
X057.C.pin = 120Ω?
Test for continuity between
X060.3 and X007.13
Test for continuity between
X060.4 and X007.24
Measured power module
CAN resistance between
X010.10.pin and
X010.11.pin = 120Ω?
Measured ground module
CAN resistance between
X007.13.soc and
X007.24.soc = 60Ω?
Measured ground module
CAN resistance between
X007.13.pin and
X007.24.pin = 120Ω?
Test harness for continuity
between X007.6.soc and
X007.17.soc
