Cruise Control Actuator Assembly

WARNING: This page is about a different car, the 1997 Acura 3.5RL. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect actuator cable from actuator rod. Disconnect actuator solenoid Gray 4-pin connector. Actuator solenoid Gray 4-pin connector is located between battery and actuator. Using a fused jumper wire, connect battery voltage to actuator solenoid Gray 4-pin connector terminal No. 4 (White wire). Using other jumper wires, ground actuator solenoid Gray 4-pin connector terminals No. 1 (Black wire), No. 2 (Brown/Black wire) and No. 3 (Brown wire). Apply vacuum to vacuum actuator vacuum check valve port. See Figure .
  2. With battery voltage, ground and vacuum applied, vacuum actuator rod should pull in completely. If vacuum actuator rod pulls in completely, go to next step. If vacuum actuator rod does not pull in or only pulls part way in, check for a vacuum leak in vacuum line or a defective vacuum actuator solenoid. Repair or replace as necessary.
  3. With battery voltage and ground still connected to vacuum actuator, pull vacuum actuator rod outward. If vacuum actuator rod cannot be pulled out, go to next step. If vacuum actuator rod can be pulled out, replace vacuum actuator.
  4. Disconnect ground wire from vacuum actuator Gray 4-pin connector terminal No. 3 (Brown wire). If vacuum actuator rod returns, go to next step. If vacuum actuator rod does not return, ensure vent hose and filter are not plugged. See Figure . If vent hose and filter are okay, using NEW "O" rings, replace solenoid valve assembly.
  5. Repeat application of voltage and vacuum from steps 1) and 2). Disconnect ground wire from vacuum actuator Gray 4-pin connector terminal No. 1 (Black wire). If vacuum actuator rod returns, go to next step. If vacuum actuator rod does not return, ensure vent hose and filter are not plugged. See Figure . If vent hose and filter are okay, using NEW "O" rings, replace solenoid valve assembly.
  6. Disconnect battery voltage and ground from vacuum actuator Gray 4-pin connector. Disconnect vacuum vent hose. Apply vacuum to vacuum actuator vent hose port. If vacuum actuator rod pulls in completely, vacuum actuator is okay. If vacuum actuator rod does not pull in completely, vacuum valve is stuck open, replace vacuum actuator.
