Causes
- Open or short circuit in resume switch wiring (open, short-to-ground, short-to-battery)
- Faulty cruise control resume switch (steering wheel or stalk)
- Poor or corroded connector at switch or control module
- Blown fuse or poor fused power/ground feeding the cruise input circuit
- Faulty body control module (BCM), cruise control module or powertrain control module (PCM) input
- Intermittent wiring damage (pinch, chafe) or connector terminal failure
Symptoms
- Cruise control will not resume speed when using the resume feature
- Resume works intermittently or only after multiple attempts
- Cruise unavailable or cruise lamp may flash/turn off
- Related cruise functions (set/accelerate/coast) may be affected
- Possible stored additional communications or input-related trouble codes
What to check
- Use a diagnostic scan tool to read stored codes, freeze frame data and live data for cruise inputs
- Verify if other cruise-related codes are present (brake switch, speed sensor, communication codes)
- Visually inspect steering-column wiring, connector backshells, and connectors at the control module for corrosion, bent pins, or damage
- Check related fuses and power/ground circuits for continuity and correct voltage
- Operate the resume switch while monitoring the input signal with a scope or multimeter to see expected change
- Perform a wiggle test on wiring harness while watching live data or repeating the failure
Signal parameters
- Supply voltage to switches commonly from battery: ~12 V (measure at fuse or switch supply)
- Switch closed (resume pressed): low resistance (typically
- Switch open (released): very high resistance (typically >10 kΩ / open) between terminals
- Module input idle voltage varies by design; typical pulled-up signal voltages: ~3–5 V, and when switched to ground should drop to
- If using a scope, expect a clean, short pulse when the resume button is tapped and a stable transition rather than noisy or intermittent signals
Diagnostic algorithm
- Retrieve codes, freeze frame and live data. Note when the code sets and any related codes.
- Verify battery voltage and inspect cruise-related fuses and power/ground circuits. Repair low voltage or blown fuse first.
- With ignition on, observe the resume input on a scan tool or scope. Have an assistant press the resume switch while watching the signal for a valid transition.
- If no transition, measure at the switch: verify supply voltage and continuity to the module. Check for short-to-ground or short-to-battery.
- Perform a continuity/resistance check of the switch (with steering column covers removed if needed). Replace switch if it fails resistance checks or behaves intermittently.
- If switch checks good, backprobe the connector at the control module and check for wiring continuity from the module pin to the switch pin. Repair damaged wiring or connector terminals as needed.
- Check module grounds and supply voltages at the module. Repair poor ground or supply faults.
- If wiring and switch are good but input signal is still not valid, consider module fault. Check for software updates and module communication. Reflash or replace module only after confirming external circuit integrity.
- Clear codes, test drive and attempt resume function to confirm repair. Monitor for return of code.
Likely causes
- Broken/shorted wiring between resume switch and module
- Failed resume switch contacts (stuck open)
- Corroded connector at steering column or module
- Bad ground or supply to the input circuit
Fault status
Status
Cruise control resume input circuit malfunction: resume signal missing, out of range, intermittent, or shorted. Inspect switch, wiring, fuses, and module inputs.
Repair difficulty: Medium
Diagnostic time: 1.0-3.0 hours
