What Does C1725 Mean?
The right rear electronically controlled damper actuator circuit is shorted to battery voltage. This means the control signal wire is making unwanted contact with a 12V source, preventing the suspension module from properly controlling the right rear shock absorber's firmness. The driver may notice uneven ride quality with the right rear feeling abnormally stiff or soft depending on the actuator's default state.
Common Causes
35%
Chafed wiring harness with the actuator control wire contacting a battery voltage source
30%
Failed right rear damper actuator with internal short to power
20%
Corroded or damaged connector at the damper actuator causing pin-to-pin cross contact
10%
Aftermarket wiring or accessories improperly tapped into the damper circuit
5%
Faulty suspension control module output driver
Diagnostic Steps
1
Disconnect the right rear damper actuator connector and measure voltage on the control wire from the module side — with the actuator disconnected, it should show the module's commanded voltage (0-12V PWM), not continuous battery voltage.
2
With the actuator disconnected, check for continuity between the control wire and battery positive or any known 12V circuit — should be OL (open).
3
Inspect the right rear damper actuator connector for signs of corrosion, water damage, bent pins, or evidence of the connector housing being cracked.
4
Measure the actuator coil resistance — should match manufacturer specification (typically 3-12 ohms). Verify no continuity exists between actuator terminals and the actuator housing/ground.
5
Trace the wiring harness from the actuator along the rear suspension, checking routing near exhaust heat shields, brake lines, and frame edges where chafing commonly occurs.

The most common cause of C1725 (Right Rear Damper Actuator Short Circuit to Battery) is: Chafed wiring harness with the actuator control wire contacting a battery voltage source
Typical repair costs for C1725 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The vehicle can be driven at reduced speeds. The right rear damper defaults to a fixed setting, which creates asymmetric handling characteristics. Avoid aggressive cornering and high-speed driving. The imbalanced damping can affect stability in emergency maneuvers.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1725 to identify the root cause.
