BRAKE LIGHT SWITCH



See Figures 1 and 2

Inspection
  1. Using an ohmmeter, check for continuity between the terminals.
  2.  
  3. While depressing the brake pedal, there should be continuity between terminals C and D of the brake light switch connector.
  4.  
  5. While not depressing the brake pedal, there should be continuity between terminals A and B of the brake light switch connector.
  6.  
  7. If the brake light switch fails any portion of this test, replace it with a new one.

INHIBITOR SWITCH



See Figures 3 and 4

Inspection
  1. Disconnect the inhibitor switch connector.
  2.  
  3. Using a suitable ohmmeter, check that there is continuity between connector (E12) terminals 3 and 5, 3 and 4 when the shift lever is moved from the N range and the P range.
  4.  
  5. If the inhibitor switch fails any portion of this test, replace it with a new one.

ACTUATOR



Inspection

See Figure 5

  1. Disconnect the actuator connector.
  2.  
  3. Using a suitable ohmmeter, check the resistance value of the clutch coil.
  4.  
  5. The resistance of the clutch coil between connector terminals 3 and 4 should be approximately 55 ohms.
  6.  
  7. If the actuator fails any portion of this test, replace it with a new one.

CLUTCH SWITCH



Inspection
  1. Using a suitable ohmmeter, check for continuity between the terminals.
  2.  
  3. While depressing the clutch pedal, there should be continuity between terminals of the clutch switch connector.
  4.  
  5. While not depressing the clutch pedal, there should be no continuity between the terminals of the clutch switch connector.
  6.  
  7. If the clutch switch fails any portion of this test, replace it with a new one.
