Causes

Open or short in actuator power or signal wiring
Poor connector connection or corrosion at the actuator harness
Blown fuse or faulty relay supplying the actuator circuit
Failed actuator motor or internal gear damage
Mechanical binding or obstruction at the mechanism the actuator moves
Faulty ground connection

Symptoms

Rear‑left function inoperative or intermittent (depends on system: door lock, liftgate, HVAC flap, suspension, etc.)
Audible abnormal noise from the rear‑left area when actuator tries to operate
Related warning lamp or message on dash, or system reduced functionality
DTC C2220 stored in ECU and may reappear after clearing

What to check

Retrieve freeze‑frame and live data with a compatible scan tool and confirm C2220 is present
Check for other related codes (communication or supply faults) that may point to a common cause
Visually inspect wiring and connectors at the rear‑left actuator for corrosion, damage, or water intrusion
Check fuses and relays feeding the actuator circuit
Backprobe actuator connector with ignition ON and command actuator from scan tool while observing voltages
Listen for actuator motor noise while commanding operation; note intermittent behavior or grinding noises

Signal parameters

Nominal supply voltage: ~12 V at connector with circuit powered (should be battery voltage minus small drop)
Control signal: either direct switched 12 V or PWM/ground drive — command signal varies 0–12 V or PWM duty 0–100% when actuator commanded
Expected current draw: small DC motor surge during movement (typical
Actuator resistance (motor or position sensor): varies by design; check service manual for spec — expect continuity for motor windings, open circuit indicates failed motor
CAN/serial data: control module should show commanded position/feedback values when actuated (if applicable)

Diagnostic algorithm

Connect a full‑function scan tool, read and record all stored codes and live data, and note any related faults or freeze frame data.
Verify power and ground to the actuator: check relevant fuses/relays and measure battery voltage at the actuator power pin with connector connected and with actuator commanded.
Command the actuator from the scan tool while monitoring voltage and current at the connector. Observe whether the actuator tries to move and whether voltage drops or current spikes occur.
If no power at actuator when commanded, trace wiring back to fuse/relay/module. Repair open/shorts, poor crimps, or corroded pins as found.
If power and control signals are present but actuator does not move, disconnect actuator and bench‑test with a direct 12 V supply (use correct polarity and short test pulses). If unit does not operate or draws excessive current, replace actuator.
If actuator moves on bench but not installed, inspect mechanical linkage and mounting for binding, misalignment or interference. Repair or lubricate as needed.
If electrical and mechanical checks are good, check control module outputs and communication lines (CAN). Update/reflash module software per manufacturer bulletins and clear codes. If module outputs are faulty, follow manufacturer procedure for module testing/replacement.
After repairs, clear DTCs, cycle system several times, and verify the fault does not return and that normal operation is restored.

Likely causes

Corroded/loose connector at rear‑left actuator
Failed actuator motor or stripped internal gears
Wiring damage (pinched, chafed, short to ground) between module and actuator
Blown fuse or poor ground

Fault status

⚠️ Status

C2220 — Rear Left (LH) actuator malfunction detected by control module. Check actuator, wiring, fuses/relays and module communication. Fault may cause loss or reduced operation of the rear‑left function.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 0.5-2.0 hours
