Causes
- Mechanical binding or obstruction in actuator gear or linkage
- Stripped or broken internal gears or latch mechanism
- Actuator motor seizure or excessive wear
- Failed position feedback sensor (potentiometer or hall sensor)
- Intermittent or poor power/ground or corroded connector
- Shorted or stuck control output from the module (PWM or ground driver)
Symptoms
- Related system remains in one state (e.g., vent stuck, door/trunk won’t latch or open)
- Actuator runs continuously or makes grinding/straining noises
- Intermittent operation or no movement from actuator
- HVAC temperature or vent position incorrect/not controllable (if HVAC actuator)
- Associated warning or fault lamp depending on system
- Possible burning smell or elevated current draw if motor is stalled
What to check
- Scan vehicle and record freeze frame & all stored/ pending codes
- Operate the affected function while watching/ listening to actuator
- Visual inspection for obstructions, broken linkages, water or corrosion
- Inspect connector for corrosion, bent pins, or poor mating
- Backprobe connector to measure supply voltage and ground during operation
- Check feedback signal (potentiometer voltage or hall output) with a DMM/scan tool
Signal parameters
- Supply voltage: ~12 V nominal at connector when actuator commanded
- Ground: low-resistance path to chassis ground (< 1 ohm typical)
- Feedback sensor: 0–5 V analog range (potentiometer) or digital hall output as specified
- Control signal: PWM or switched 12 V depending on module (often 50–300 Hz for PWM)
- Typical running current: low hundreds of mA; stall current higher — compare to service spec
- Resistance of actuator windings: consult service data (open or short indicates failure)
Diagnostic algorithm
- Read and record C2202 and any related codes with a capable scan tool. Clear codes and attempt to re-run the operation to reproduce the failure.
- Visually inspect actuator, linkage, mounting, and harness for damage, obstructions, water, or corrosion.
- With ignition ON, command the actuator via the scan tool (if available) while listening and watching movement. Note noise, movement, and position feedback values.
- Backprobe power and ground at the actuator connector during a commanded run. Verify ~12 V supply and a good ground. If supply or ground missing, trace wiring, fuses, and relays.
- Measure feedback (position) signal during operation. If feedback does not change while actuator is commanded, suspect mechanical failure or failed feedback sensor.
- Measure actuator current while operating. Abnormally high current indicates binding or stalled motor; zero or open indicates motor/winding open or connector issue.
- If electrical inputs are correct but actuator does not move or is noisy, remove actuator and perform bench test (apply appropriate voltage and observe movement and feedback). Inspect internal gears for damage.
- If bench test passes, inspect vehicle linkage and re-check installation orientation and adjustment. Correct binding or replace broken linkage.
- If actuator fails bench test or feedback sensor out of spec, replace actuator. Use OEM or equivalent part and ensure correct gear orientation and calibration if required.
- After repair or replacement, clear codes and perform system calibration/adaptation procedures as specified by manufacturer. Verify proper operation and re-scan to confirm code does not return.
Likely causes
- Physical jam or binding in the actuator or its linkage
- Broken/stripped internal gears preventing latching
- Failed feedback sensor reporting incorrect position
- Open/short in wiring causing continuous drive to actuator
Fault status
Status
Actuator stuck ON or latching failure detected — mechanical binding, broken latch/gears, or feedback failure causing improper position or continuous drive.
Repair difficulty: Medium
Diagnostic time: 0.5-2.5 hours
