What Does C1416 Mean?
The suspension control module has detected a short-to-battery (B+) condition in the right front (RF) electronically controlled damper (shock absorber) circuit. This means unwanted positive voltage is present on the damper control wiring, preventing proper adjustment of the RF shock absorber's damping force. The adaptive suspension warning light will illuminate and the RF damper will default to a fixed setting.
Common Causes
35%
Wiring harness damage with RF damper wire contacting a power source
25%
RF electronic damper actuator internal short to power
20%
Connector pin damage or corrosion causing cross-contact with power circuit
10%
Previous improper repair or aftermarket wiring cross-feeding voltage
10%
Suspension control module internal driver fault with voltage backfeed
Diagnostic Steps
1
Disconnect the suspension control module connector. Measure voltage on the RF damper circuit pins — should read 0V. Voltage present indicates an external power backfeed in the harness.
2
Disconnect the RF damper actuator connector at the shock absorber. Re-measure voltage at the harness mid-point to isolate whether the short is in the upper harness (to module) or lower harness (to damper).
3
Inspect the RF damper wiring along the entire route from the body harness through the wheel well to the damper. Look for insulation damage where wires pass near the strut tower, fender bracket, or any power supply wires.
4
Check the RF damper actuator connector for corrosion, water intrusion, and pin condition. Measure resistance between each actuator pin and the actuator housing — should be OL (no short to case).
5
If no harness fault is found, reconnect the harness and use the scan tool to command damper stiffness changes while monitoring the driver circuit — constant voltage output regardless of commands indicates a module failure.

The most common cause of C1416 (Damper RF Circuit Short To Battery) is: Wiring harness damage with RF damper wire contacting a power source
Typical repair costs for C1416 range from $150 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The RF damper will revert to a fixed (usually firm) setting. Ride comfort may be noticeably different, and the vehicle may handle unevenly since the other three corners are still adapting. Safe to drive at normal speeds, but the ride quality will be degraded. Schedule repair at your convenience.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1416 to identify the root cause.
