Component Diagnosis & Testing
CONTROL MODULE1. Measure voltage at cruise control unit terminals as indicated in Fig. 37.
Fig. 37 Cruise Control Module Inspection:
2. If voltage is not as specified in Fig. 37, replace control unit.
ACTUATOR
1. Measure resistance between actuator terminals A and C and between terminals B and D, Fig. 38.
Fig. 38 Cruise Control Actuator Location & Terminal Identification:
2. If resistance between terminals A and C is not 14.4 ohms or resistance between terminals B and D is not 10.2 ohms, replace actuator.
3. Connect B+ and ground to terminals as shown in Fig. 39 and ensure actuator cable operation is as specified. If it is not, replace actuator.
