DTC P0565, Cruise Switch Circuit Malfunction: Notes
Command state voltage levels are divided through a resistor network from ignition voltage through CRUISE fuse. Network consists of resistors in cruise control switch and PCM. If voltage level is within an acceptable window, PCM will decode the signal. Voltage level windows may vary due to battery calculations.
DTC P0565 will set if:
- When cruise control system is on, less than 0.5 volt or greater than one volt is present on circuit No. 1884 (Gray wire).
- When RESUME/ACCEL switch is pressed, less than 1.2 volts or greater than 2.4 volts is present on circuit No. 1884 (Gray wire).
- When SET/COAST switch is pressed, less than 3 volts or greater than 3.5 volts is present on circuit No. 1884 (Gray wire).
- Turn ignition on, engine off. Connect scan tool. Turn cruise control system off. If DTC P0565 is present, go to step 5). If DTC P0565 is not present, go to next step.
- Turn cruise control switch on. If DTC P0565 is present, replace cruise control switch. If DTC P0565 is not present, go to next step.
- Press and hold SET/COAST switch. If DTC P0565 is present when SET/COAST switch is pressed, replace cruise control switch. If DTC P0565 is not present when SET/COAST switch is pressed, go to next step.
- Press and hold RESUME/ACCEL switch. If DTC P0565 is present when RESUME/ACCEL switch is pressed, replace cruise control switch. If DTC P0565 is not present when RESUME/ACCEL is pressed, problem is intermittent. See DIAGNOSTIC AIDS.
- Turn ignition off. Disable air bag system. See DISABLING & ACTIVATING AIR BAG SYSTEM . Remove air bag module. See AIR BAG (INFLATOR) MODULE . Disconnect cruise control switch connector. Turn ignition on. If DTC P0565 is present, go to next step. If DTC P0565 is not present, replace cruise control switch.
- Turn ignition off. Remove steering column cover. Disconnect Black 4-pin SIR roll connector. Turn ignition on. If DTC P0565 is present, repair short to power in Gray wire or PCM. If DTC P0565 is not present, replace roll connector.
