COMPONENT TESTING



Slip Ring
  1. Remove column cover, then disconnect 3 pin connector.
  2.  
  3. Check continuity between connector terminal with blue/red wire and terminal A .
  4.  
  5. Check continuity between connector terminal with light green/red and terminal B .
  6.  
  7. Check continuity between connector terminal with light green/black and terminal C .
  8.  
  9. Replace slip ring assembly if 1 or more do not have continuity.
  10.  

Actuator Solenoid

See Figure 1

  1. Disconnect 4 pin connector from actuator solenoid.
  2.  
  3. Connect ohmmeter between connector terminal with brown/white wire and brown/black wire (vacuum solenoid) and measure resistance. Resistance should be 30-50-.
  4.  

Resistance will vary slightly with temperature. Resistance values given are at 70°F (21°C).

  1. Connect ohmmeter between connector terminal with brown/white wire and brown wire (vent solenoid) and measure resistance. Resistance should be 40-60-.
  2.  

  1. Connect ohmmeter between connector terminal with brown/white wire and black wire (safety solenoid) and measure resistance. Resistance should be 40-60-.
  2.  
  3. If any resistance values are not as specified, check/replace actuator solenoid.
  4.

Actuator

See Figures 2 through 6

  1. Disconnect actuator cable from actuator rod.
  2.  
  3. Disconnect 4 pin connector.
  4.  
  5. Connect battery positive wire to brown/white terminal and negative to brown/black, brown and black terminals.
  6.  
  7. Connect a vacuum pump to check valve. Then apply vacuum to actuator.
  8.  
  9. Actuator rod should pull in completely. If rod pulls in only part way or not at all for a leaking vacuum line or defective solenoid.
  10.  
  11. With voltage and vacuum still applied, try to pull actuator rod out by hand. Actuator rod should not pull out. If it does, replace actuator.
  12.  
  13. Disconnect battery negative wire from brown terminal. Actuator rod should return. If it does not return and ventilation hose and filter are free, replace actuator.
  14.  
  15. Repeat Steps 3-7, but disconnect battery negative wire from black terminal. Actuator rod should return. If not and ventilation hose and filter are free, replace solenoid valve assembly.
  16.  

If solenoid valve assembly is replaced, be sure to use new O-rings at each solenoid.
