▪
IF the fuse is NOT blown, verify with a multimeter the 24V between
X37-pin1 and X37-pin2 (A10 board side).
o
IF X37 24V is OK, verify the 3D sensor ON signal, driven by CCU:
5V between the X38-pin 1 and X38-pin 7(GND).
-
IF 5V is OK, verify cable X42-J99 (between the A10 board
and the 3D sensor): if faulty fix or replace it. If the LED H2
is still OFF, replace the 3D Power Sensor board A10
-
IF 5V is NOT OK, verify the integrity of the cable X38-X61
(between 3D Power Sensor board A10 and CCU board A11)
and the cable X9-X9 (between MCU board A1 and CCU
board A11)
➢
IF the X38-X61 or X9-X9 are NOT OK, fix or replace
them
➢
IF the X38-X61 or X9-X9 are OK, replace the MCU board
A1.
o
IF the X37 24V is NOT OK, disconnect the X37 connector (A10
board side) and verify if between X37-pin1 and X37-pin2 (cable
side), there are 24V.
-
IF X37 24V is now OK, replace the 3D Power Sensor board
A10
-
IF X37 24V is still NOT OK, verify the cable X11-X37 and
perform the 24V power supply verification (see paragraph
11.2.3)
c.
Activate the sensor logs (see paragraph 11.2.1.4) and perform an
acquisition in order to reproduce the error.
