Test
Basic check of likely causes
Voltage between X074.1 and
X074.2 = Vbatt?
Measured RESISTANCE be-
tween X012.3 Red wire and
X012.4 Black = 60Ω?
Measured RESISTANCE be-
tween X075.9.soc and
X075.10.soc = 60Ω?
Measured RESISTANCE be-
tween X057.A.pin and
X057.C.pin = 60Ω?
Measured RESISTANCE be-
tween X054.1.soc and
X054.3.soc = 120Ω?
Test for continuity between
X075.9 and X007.13
Test for continuity between
X075.10 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.pin and
X007.24.pin = 120Ω?
Test harness for continuity
between X007.6.soc and
X007.17.soc
