Test SP-2C, Code 34, Cruise Control Solenoid Circuit

  1. Probe terminal No. 53 (Light Green/Red wire) at Single Board Engine Controller (SBEC) connector. If voltage is 10 volts or more, replace SBEC. Perform VERIFICATION TEST SP-VER  . If voltage is less than 10 volts, disconnect cruise control 4-pin servo connector. Inspect con-nector.
  2. If connector is not okay, repair connector as necessary. Perform VERIFICATION TEST SP-VER  . If connector is okay, put DRB-II in ohmmeter mode. Probe terminal No. 3 (Light Green/Red wire) at servo connector. If resistance is less than 10 ohms, repair short to ground in Light Green/Red wire. Perform VERIFICATION TEST SP-VER  . If resistance is 10 ohms or more, go to next step.
  3. Using an external ohmmeter, check resistance at Light Green/Red wire between terminal No. 53 at SBEC connector and terminal No. 3 at cruise control servo connector. If resistance is less than 10 ohms, replace cruise control servo. Perform VERIFICATION TEST SP-VER  . If resistance is 10 ohms or more, repair open Light Green/Red wire. Perform VERIFICATION TEST SP-VER  .
