Cruise Control Inoperative: Notes

  1. Connect scan tool. Turn ignition switch to RUN position. Check for Diagnostic Trouble Codes (DTCs). If any DTC is present, see appropriate DTC. If no DTCs are present, go to next step.
  2. Operate horn. If horn operates, go to next step. If horn does not operate, repair open in ground for cruise control and horn switches.
  3. Check ON/OFF switch inputs on scan tool. If scan tool recognizes ON/OFF switch inputs, go to step 7). If scan tool does not recognize ON/OFF switch inputs, go to next step.
  4. Disable air bag system. See the DISABLING & ACTIVATING AIR BAG SYSTEM  . Remove air bag module. See AIR BAG (INFLATOR) MODULE  under REMOVAL & INSTALLATION. Disconnect cruise control switch. Using a 5-amp fused jumper wire, jumper Brown and Gray wires at cruise control switch. Turn ignition on, engine off. If DTC P0565 is not present, go to next step. If DTC P0565 is present, replace cruise switch.
  5. Remove steering column cover. Disconnect 4-pin SIR roll connector. Using 5-amp jumper wire, jumper roll connector terminal "D" (Brown wire) to terminal "C" (Gray wire) on harness side. If DTC P0565 is not present, go to next step. If DTC P0565 is present, replace roll connector.
  6. Using Digital Volt-Ohmmeter (DVOM), check voltage between Brown wire and ground. If battery voltage is not present, repair open in Brown wire. If battery voltage is present, check for open in Gray wire. If circuit is okay, replace PCM.
  7. Check SET/COAST switch inputs on scan tool. If scan tool recognizes SET/COAST switch inputs, go to next step. If scan tool does not recognize SET/COAST switch inputs, replace cruise control switch.
  8. Check RESUME/ACCEL switch inputs on scan tool. If scan tool recognizes RESUME/ACCEL switch inputs, go to next step. If scan tool does not recognize RESUME/ACCEL switch inputs, replace cruise control switch.
  9. Using Digital Volt-Ohmmeter (DVOM), backprobe between cruise control module terminal No. 7 (Brown wire) and ground. If battery voltage is not present, repair open in Brown wire. If battery voltage is present, check for a poor connection in Brown wire. If circuit is okay, replace cruise control module.
