DTC 01: Actuator Circuit

WARNING: This page is about a different car, the 2002 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition to ON position. Push cruise control main switch to ON position. Using a DVOM, backprobe actuator harness connector terminal "B" (Green/Black wire). See Figure . If battery voltage exists, go to step  7 . If battery voltage does not exist, go to next step.
  2. Disconnect cruise brake switch connector. Turn ignition to ON position. Push cruise control main switch ON. Measure voltage at cruise brake switch connector terminal 2A (White wire). If battery voltage exists, go to step  5 . If battery voltage does not exist, go to next step.
  3. Remove lower panel cover. Remove cruise control module with harness still connected. Using voltmeter, backprobe cruise control module harness connector terminal "H" (White wire). See Figure . If battery voltage exists, repair wiring harness between cruise control module terminal "H" and cruise brake switch. If battery voltage does not exist, go to next step.
  4. Disconnect cruise control module. Using a DVOM, measure for continuity between cruise control module harness connector terminal "H" and ground. If continuity exists, repair wiring harness between cruise control module terminal "H" and cruise brake switch. See WIRING DIAGRAMS  . If continuity does not exist, replace cruise control module. See CRUISE ACTUATOR  under REMOVAL AND INSTALLATION.
  5. Measure continuity at cruise brake switch harness connector terminal 2B (Pink wire) and ground. If continuity exists, go to next step. If continuity does not exist, check cruise brake switch. Repair or replace as necessary.
  6. Measure continuity between cruise control module connector terminal "M" (Pink wire) and ground. If continuity exists, repair wiring harness between cruise control module terminal "M" and cruise brake switch. See WIRING DIAGRAMS  . If continuity does not exist, replace cruise control module. See CRUISE ACTUATOR  under REMOVAL AND INSTALLATION.
  7. Measure voltage at cruise control module terminals "A" (Red wire) , "B" (Green/Black wire) and "C" (Green/Orange wire). See WIRING DIAGRAMS  . If battery voltage is present, replace cruise control module. See CRUISE ACTUATOR  under REMOVAL AND INSTALLATION. If battery voltage is not present, go to next step.
  8. Measure voltage at cruise control actuator terminals "A" (Green/Orange wire), "C" (Pink wire) and "D" (Red wire). If battery voltage is present, repair wiring harness between cruise actuator and cruise control module. See WIRING DIAGRAMS  . If battery voltage is not present, go to next step.
  9. Disconnect cruise control module and cruise actuator. Measure continuity at cruise control module and cruise actuator harness wiring harness connectors terminals "A", "C", and "D". If continuity exists, repair wiring harness between cruise actuator and cruise control module. See WIRING DIAGRAMS  . If continuity does not exist, go to next step.
  10. Check cruise actuator. See ACTUATOR  under COMPONENT TESTS. If cruise actuator is okay, replace cruise control module. If cruise actuator is not okay, replace cruise actuator. See CRUISE ACTUATOR  under REMOVAL & INSTALLATION.
