P0567 - Cruise Control 'Resume' Signal
System
Powertrain (Engine & Gearbox)
Technical Description
The control module has detected a fault in the Cruise Control 'Resume' Signal (P0567). The reported signal is electrically valid but disagrees with other operating parameters (RPM, load, or other sensors).
Multimeter Test Points & Nominal Values
| Test Point / Component | Measurement | Nominal Target Range | Test Condition |
|---|---|---|---|
| Cruise Control 'Resume' Signal – Permanent B+ Supply | Voltage (V) | 12.4 - 12.7 V (ignition OFF) / 13.5 - 14.7 V (engine running) | At module supply pins |
| Cruise Control 'Resume' Signal – Ignition-Switched Supply | Voltage (V) | 11.8 - 14.4 V | Ignition ON |
| Cruise Control 'Resume' Signal – Ground Connections Voltage Drop | Voltage (V) | < 0.1 V per ground point | Under load to battery negative |
| Cruise Control 'Resume' Signal – 5 V Reference Outputs | Voltage (V) | 4.95 - 5.05 V per circuit | Ignition ON, sensors unplugged one at a time |
At module supply pins
Ignition ON
Under load to battery negative
Ignition ON, sensors unplugged one at a time
Oscilloscope Waveform Analysis
500 ms/div, 5 V/divPossible Causes
Cruise Control 'Resume' Signal is electrically operational but performing outside calibrated tolerance
Chafed or pinched wiring harness along the signal path to Cruise Control 'Resume' Signal
Poor ground connection or excessive voltage drop (> 0.1 V) at the ground point for Cruise Control 'Resume' Signal
Defective internal output driver or reference circuit in the control module for Cruise Control 'Resume' Signal

Recommended Solution
Log component live data across varying load points and verify plausibility against engine target model.
Verify loaded supply voltage and harness terminal pins at Cruise Control 'Resume' Signal.
Check circuit continuity and ground-side voltage drop (< 0.05 V) for Cruise Control 'Resume' Signal.
Inspect module enclosure and connector headers for water ingress, fretting corrosion, or PCB thermal damage.
Mechanic's Tip
When facing a 5V reference supply DTC, never replace the module first. A shorted external sensor (such as A/C pressure or EGR position) drags down the shared 5V internal rail. Unplug sensors one by one until 5V recovers.
