Detach the assembly sensor from the
ASS'Y PCB CN43 connector and measure
the sensor resistance with an ohmmeter (tester)
between Pin #1 and #2.
Connect the sensor to CN43,
supply power, and measure the voltage of
#1 and #2 of the CN43 connector.
MICOM Error or Connector(CN43) check
Is the sensor resistance value
10KΩ ±3% at the room temperature
