Causes
- Open or shorted coast switch circuit (wiring or connector)
- Faulty cruise control coast switch (on steering wheel or stalk)
- Corroded, loose, or damaged connector at switch or module
- Blown fuse or poor power/ground to cruise/cruise switch circuit
- Intermittent wiring fault (pinched, chafed, or water intrusion)
- Faulty cruise control module, BCM, or ECM input driver
Symptoms
- Cruise control will not coast, set, or maintain speed
- Cruise control disengages unexpectedly or won't engage
- Malfunction Indicator Lamp (MIL) or Cruise/Vehicle warning lamp may be illuminated
- Intermittent or inconsistent cruise control behavior
- Stored P0569 (possibly along with other cruise-related codes)
What to check
- Read and record all stored codes and freeze frame data with a scan tool
- Check for other related codes (brake/clutch/other cruise inputs, power/ground faults)
- Visually inspect steering wheel switch, connector, and harness for damage or corrosion
- Verify fuses and power/ground for cruise system and related modules
- Backprobe coast switch connector and monitor signal with a multimeter or scope while operating switch
- Wiggle-test wiring through steering column to reproduce intermittent faults
Signal parameters
- Typical coast switch type: simple momentary switch to ground (active low) or to 12 V depending on vehicle
- Inactive voltage: typically near battery voltage (approx. 4.5–12 V depending on pull-up) or open circuit
- Active voltage (switch pressed): typically near 0–0.5 V if active-low, or near battery voltage if active-high
- Switch continuity when pressed: near 0 Ω between switch terminal and ground (if active-low)
- Use oscilloscope to confirm clean digital transition; look for bouncing, noise, or intermittent dropouts
Diagnostic algorithm
- Retrieve freeze frame and live data. Note related codes and the module reporting P0569.
- Visually inspect coast switch, steering column wiring, and connectors for damage, corrosion, or intrusion of water.
- Verify power and ground: check relevant fuses and battery voltage at cruise module and switch circuit.
- Backprobe the coast switch connector. With a multimeter measure voltage at the input pin while operating the switch: verify expected inactive and active voltages per vehicle design (active typically 0–0.5 V for active-low circuits).
- If voltages are incorrect, perform continuity checks from the switch pin to the cruise module/BCM pin using ohmmeter; check for short to ground or short to battery.
- Wiggle the steering column harness while monitoring the live signal to detect intermittent faults caused by movement.
- If wiring and connectors are good, isolate the switch by disconnecting it and testing switch continuity directly. Replace switch if it fails continuity/voltage behavior.
- Repair wiring, connectors, or grounds as required. If evidence points to module input driver failure (no change after wiring/switch verified), consider module replacement or bench testing per manufacturer procedures.
- Clear codes, perform a road test and verify cruise operation. Re-scan to confirm the code does not return.
Likely causes
- Faulty coast switch on steering wheel
- Broken or shorted wire between coast switch and cruise module
- Corroded connector or poor ground at the switch or module
- Blown fuse or supply voltage problem to cruise switch circuit
- Intermittent connector contact due to steering column movement
Fault status
Status
Cruise control coast input signal invalid or out of expected range — check coast switch, wiring, fuses, grounds, and module inputs.
Repair difficulty: Medium
Diagnostic time: 0.5-2.0 hours
