CMBS OFF Switch Removal, Installation, and Test: Test

CMBS OFF Switch Continuity Check: 

1. On the switch side, check for continuity between the CMBS OFF switch/RDM switch 12P connector (male terminals) terminals in each switch position according to the table.

   If the switch does not work as described in the table, replace the CMBS OFF switch/RDM switch.

RDM Switch Internal Resistance Check: 

1. Measure the resistance between CMBS OFF switch/RDM switch 12P connector (male terminals) terminals No. 8 and No. 11 according to the table.

   If there is no resistance in one or more positions, replace the CMBS OFF switch/RDM switch.

   RDM SWITCH INTERNAL RESISTANCE SPECIFICATION
   
   

   Position	Resistance at normal ambient temperature
   Released	12.1-14.8 kΩ
   Pressed and held	3.1-3.8 kΩ

RDM Switch Indicator Drive Circuit Check: 

1. Check the LED for illumination by applying power and ground to the terminals according to the table.
   NOTE: Important operating characteristic; diode bias cause a diode to fully conduct electricity in one direction (forward), while not at all in the opposite direction (reverse).

   If the results are not as specified, replace the CMBS OFF switch/RDM switch.

Switch Illumination Circuit Check: 

1. Check the LED for illumination by applying power and ground to the terminals according to the table.
   NOTE: Important operating characteristic; diode bias cause a diode to fully conduct electricity in one direction (forward), while not at all in the opposite direction (reverse).

   If the results are not as specified, replace the CMBS OFF switch/RDM switch.
