Causes

Open or shorted wiring between switch and PCM
Corroded, damaged, or loose connector at the switch or PCM
Faulty acceleration/cruise control switch (stuck or intermittent)
Blown fuse or poor ground affecting the circuit
Module communication error or PCM fault
Incorrect calibration, software or programming issue

Symptoms

Cruise control will not set or is disabled
Cruise disengages unexpectedly
Malfunction Indicator Lamp (MIL)/Check Engine Light illuminated
Possible reduced or erratic throttle response (drive-by-wire vehicles)
Stored P0570 code in ECU memory

What to check

Read and record all stored and pending DTCs and freeze frame data with a scan tool
Verify battery voltage and relevant fuse(s) for the cruise/accel switch circuit
Visually inspect wiring and connectors at the switch, pedal assembly and PCM for damage or corrosion
Operate the acceleration/cruise switch while monitoring the corresponding PID or switch state with a scanner
Check for related communication codes (CAN/ECU) that could affect switch reporting

Signal parameters

Switch expected states: open (off) and closed (on) or discrete 0V/12V depending on design
For pedal position sensors: analog voltage typically ~0.5–4.5 V per sensor (two-channel redundant systems)
Signal should change smoothly when actuating the switch or pedal; no intermittent drops to 0V
CAN/serial data: cruise/accel switch status present and consistent on vehicle network (if applicable)

Diagnostic algorithm

Use a scanner to confirm P0570 and note any other stored codes. Record live data PIDs for cruise switch/pedal and related sensors.
Attempt to replicate the fault by operating the cruise/acceleration switch while watching the scanner for changes or dropouts.
Visually inspect connectors and wiring for damage, corrosion, pin bending, or water ingress at the switch, steering column/pedal area and PCM.
Check associated fuses and grounds. Wiggle test wiring harness while monitoring live data to reveal intermittent opens/shorts.
Perform a continuity and resistance check between the switch terminal and PCM connector with ignition off. Repair any open or shorted circuits.
With ignition on, backprobe the switch connector and measure voltage/ground reference while actuating the switch. Compare to expected signal parameters.
If the circuit and switch test OK, check vehicle network communications (CAN) for errors. Address any bus faults or related module failures.
If wiring and network are good but fault persists, replace the cruise/acceleration switch and retest. Clear codes and perform a road test to confirm repair.
If replacement switch does not clear fault, consider PCM software update or module replacement as directed by manufacturer diagnostics.

Likely causes

Damaged wiring harness at steering column or pedal area
Water/contamination in connector causing intermittent contact
Failed switch contacts or internal switch electronics
Unmounted/loose ground at the PCM or switch
Aftermarket equipment interfering with signal (alarms, cruise delete)

Fault status

⚠️ Status

Cruise control/acceleration switch circuit failure detected — open, short, or invalid signal. Cruise control may be disabled and MIL may be illuminated.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 0.5-2.0 hours
