Yes

No

No

Detach the assembly sensor from the

ASS'Y PCB CN43 connector and measure 

the sensor resistance with an ohmmeter (tester).

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
