DTC P1595: Speed CTRL Solenoid Circuits

NOTE: For connector terminal ID, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS article.
NOTE: Speed Control (SC) solenoids circuits are monitored when ignition and speed control is on, vehicle speed is greater than 25 MPH and transaxle is in Drive. DTC may be stored in Powertrain Control Module (PCM) if PCM actuates the vacuum and vent solenoids and solenoids do not operate. Possible causes are: improperly adjusted brake switch, defective brake switch, defective speed control servo, defective PCM, or defective connectors or wiring.
  1. Turn ignition on with engine off. Turn speed control on/off switch on the steering wheel to ON position. Using scan tool, actuate S/C vent solenoid and listen for clicking sound at speed control servo. Speed control servo is located in engine compartment, near driver's side strut tower. See Fig 1. If clicking sound is heard at speed control servo, go to next step. If clicking sound is not heard at speed control servo, go to step  6.

  2. Ensure ignition is on and speed control on/off switch is in ON position. Using scan tool, actuate S/C vacuum solenoid and listen for clicking sound at speed control servo. If clicking sound is heard at speed control servo, go to next step. If clicking sound is not heard at speed control servo, go to step  5.
  3. Turn ignition off. Inspect wiring harness and connectors between speed control servo, brake switch and PCM. Brake switch is located near top of brake pedal. PCM is located at driver's side front corner of engine compartment, just below air cleaner assembly. If no problems exist, go to next step. If any problems exist, repair wiring or connectors as necessary. Perform TEST VER-4A .
  4. Turn ignition on with engine off. Turn speed control on/off switch to ON position. Using scan tool, actuate S/C vacuum solenoid and wiggle wiring harness and connectors between speed control servo, brake switch and PCM. If actuation of S/C vacuum solenoid on speed control servo was not interrupted while wiggling wiring harness and connectors, go to next step. If actuation of S/C vacuum solenoid on speed control servo was interrupted while wiggling wiring harness and connectors, repair wiring or connectors as necessary that caused the actuation to be interrupted. Perform TEST VER-4A .
  5. Ensure ignition is on and speed control on/off switch is in ON position. Using scan tool, actuate S/C vent solenoid and wiggle wiring harness and connectors between speed control servo, brake switch and PCM. If actuation of S/C vent solenoid on speed control servo was not interrupted while wiggling wiring harness and connectors, test is complete. If actuation of S/C vent solenoid on speed control servo was interrupted while wiggling wiring harness and connectors, repair wiring or connectors as necessary that caused the actuation to be interrupted. Perform TEST VER-4A .
  6. Turn ignition off. Disconnect connector at speed control servo. Turn ignition on with engine off. Turn speed control on/off switch to ON position. Using voltmeter, check voltage at terminal No. 3 (Dark Blue/Red wire) on connector for speed control servo. DO NOT depress brake pedal when checking voltage. If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, go to step  13.
  7. Ensure ignition is off. Using ohmmeter, check resistance between ground and terminal No. 4 (Black wire) on connector for speed control servo. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open circuit on Black wire and ground connection. Perform TEST VER-4A .
  8. Disconnect connectors at PCM. PCM is located at driver's side front corner of engine compartment, just below air cleaner assembly.
  9. Ensure connector is disconnected at speed control servo. Using ohmmeter, check resistance between terminal No. 1 (White/Violet wire) on connector for speed control servo and PCM connector terminal No. 56 (White/Violet wire). If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open circuit on White/Violet wire between PCM and speed control servo. Perform TEST VER-4A .
  10. Ensure connectors are still disconnected at PCM. Using ohmmeter, check resistance between ground and terminal No. 1 (White/Violet wire) on connector for speed control servo. If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, repair short to ground on White/Violet wire between PCM and speed control servo. Perform TEST VER-4A .
  11. Ensure connectors are still disconnected at PCM and speed control servo. Using ohmmeter, check resistance between terminal No. 2 (Light Green/Red wire) on connector for speed control servo and PCM connector terminal No. 80 (Light Green/Red wire). If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open circuit on Light Green/Red wire between PCM and speed control servo. Perform TEST VER-4A .
  12. Ensure connectors are still disconnected at PCM. Using ohmmeter, check resistance between ground and terminal No. 2 (Light Green/Red wire) on connector for speed control servo. If resistance is 5 ohms or more, replace speed control servo. Perform TEST VER-4A . If resistance is less than 5 ohms, repair short to ground on Light Green/Red wire between PCM and speed control servo. Perform TEST VER-4A .
  13. Ensure ignition is off. Disconnect connector at brake switch. Brake switch is located near top of brake pedal. Turn ignition on with engine off. Using voltmeter, check voltage at terminal No. 3 (Yellow/Pink wire) on connector for brake switch. DO NOT depress brake pedal when checking voltage. If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, go to step  19.
  14. Using ohmmeter, check resistance between ground and terminal No. 3 (Yellow/Pink wire) on connector for brake switch. This wire comes out of brake switch and becomes a Yellow/Red wire at PCM. If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, repair short to ground in Yellow/Pink wire and Yellow/Red wire between PCM and brake switch. Perform TEST VER-4A .
  15. Turn ignition off. Reinstall connector on brake switch. Brake switch adjustment must be checked. To check brake switch adjustment, depress brake pedal. Ensure brakelights come on. Release brake pedal. Ensure brakelights go off. If brakelight operation is not as specified, go to next step. If brake switch is properly adjusted and brakelight operation is correct, go to step  18.
  16. To adjust brake switch, hold brake pedal downward. Rotate brake switch counterclockwise approximately 30 degrees and pull brake switch rearward from mounting bracket.
  17. Pull plunger on brake switch outward to fully extended position. Depress brake pedal as far as possible. Install brake switch in mounting bracket. Ensure alignment tab on brake switch aligns with opening on mounting bracket. When brake switch is fully installed, rotate brake switch clockwise approximately 30 degrees. To ensure proper adjustment, gently pull brake pedal back toward brake switch as far as possible. DO NOT apply excessive pressure on brake pedal and brake switch. Once brake switch is properly adjusted, perform TEST VER-4A .
  18. Ensure connectors are disconnected at brake switch and speed control servo. Using ohmmeter, check resistance between terminal No. 4 (Dark Blue/Red wire) on connector for brake switch and terminal No. 3 (Dark Blue/Red wire) on connector for speed control servo. If resistance is less than 5 ohms, replace brake switch. Perform TEST VER-4A . If resistance is 5 ohms or more, repair open circuit on Dark Blue/Red wire between brake switch and speed control servo. Perform TEST VER-4A .
  19. Using ohmmeter, check resistance between ground and terminal No. 3. (Yellow/Pink wire) on connector for brake switch. This wire comes out of brake switch and becomes a Yellow/Red wire at PCM. If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, repair short to ground on Yellow/Pink wire and Yellow/Red wire between brake switch and PCM. PCM is located at driver's side front corner of engine compartment, just below air cleaner assembly. Perform TEST VER-4A .
  20. Ensure ignition is off. Disconnect connectors at PCM. PCM is located at driver's side front corner of engine compartment, just below air cleaner assembly.
  21. Using ohmmeter, check resistance between terminal No. 3 (Yellow/Pink wire) on connector for brake switch and PCM connector terminal No. 5 (Yellow/Red wire). This wire comes out of brake switch as a Yellow/Pink wire and becomes a Yellow/Red wire at PCM. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-4A . If resistance is 5 ohms or more, repair open circuit on Yellow/Pink wire and Yellow/Red wire between PCM and brake switch. Perform TEST VER-4A .
