Cruise Control Unit Input Test

SRS components are located in this area. Review the SRS component locations (see COMPONENT LOCATION INDEX ) and precautions and procedures (see PRECAUTIONS AND PROCEDURES ), before doing repairs or service.

  1. Disconnect the 14P connector from the control unit.
  2. Inspect the connector and socket terminals to make sure they are all making good contact.
    • If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
    • If the terminals look OK, go to step 3.

  3. With the 14P connector disconnected, do these input tests.
    • If a test indicates a problem, find and correct the cause, then recheck the system.
    • If all the input tests prove OK, the cruise control unit may be faulty. Substitute a know-good cruise control unit and retest. If the system works properly, replace the cruise control unit.
      TEST CONDITION

      12 BLU/WHT Ignition switch ON (II) and cruise control main switch ON; raise the front of the vehicle, and rotate one wheel slowly while holding the other wheel
      NOTE: This input test must be done with the UP connector reconnected.
      		 Check for voltage between the BLU/WHT and ground terminal: There should be 0-5 V or more repeatedly.
      • Faulty PCM [A/T)
      • Faulty VSS (M/T)
      • An open in the wire
      • Short to ground
      13 LT GRN Ignition switch ON (II) and cruise control main switch ON Check for voltage to ground: There should be battery voltage.
      • Blown No. 4 (10 A) fuse in the under-dash fuse/relay box
      • Faulty cruise control main switch
      • An open in the wire
      14 LT BLU A/T: Shift lever in D or D3
      M/T: Clutch pedal released      		 Check for continuity to ground: There should be continuity.
      NOTE: There should be no continuity when the clutch pedal is pressed or when the shift lever is in other positions.
      • Faulty transmission range switch
      • Faulty clutch pedal position switch
      • Poor ground (M/T: G4O2, A/T: G1O1)
