What Does C1467 Mean?
This code indicates the high-side driver circuit for the rear damper actuators is shorted to battery voltage. Similar to C1465 for the front, this fault means battery voltage is present on the rear damper power supply line when it should be controlled by the module's PWM output. The rear dampers may be locked in maximum firmness or the module may disable rear damper control entirely.
Common Causes
35%
Rear damper harness wire contacting a rear body power feed wire where the harness routes along the rear wheelhouse or trunk area
25%
Rear damper actuator solenoid coil insulation failure causing an internal short to the power rail
25%
Suspension module rear high-side output driver MOSFET shorted, applying continuous battery voltage to the rear damper circuit
15%
Aftermarket trailer wiring or rear accessory installation that has inadvertently bridged battery voltage to the damper circuit
Diagnostic Steps
1
Step 1: Disconnect the rear damper actuator connectors and check for battery voltage on the high-side wire at the harness connector with key on. Voltage present with actuators disconnected confirms a harness short or module driver failure.
2
Step 2: Measure each rear damper solenoid resistance (typically 3-8 ohms) and insulation resistance to the damper body. A low insulation reading indicates a solenoid with internal insulation breakdown.
3
Step 3: Inspect the rear damper harness routing carefully, especially in the trunk/cargo area where luggage or cargo loading may have pinched or abraded the wiring. Also check near the rear wheelhouse where the harness transitions from body to suspension.
4
Step 4: Check for recently installed trailer wiring or rear-mounted accessories that may have tapped into wires near the damper harness. Aftermarket T-taps and scotch-lock connectors commonly cause cross-circuit shorts.
5
Step 5: Repair all damaged wiring, remove any improper aftermarket connections, and verify the rear damper circuit is free of external voltage. Clear codes and confirm rear damping adjustment works properly through all modes.

The most common cause of C1467 (Damper High Side Rear Circuit Short To Battery) is: Rear damper harness wire contacting a rear body power feed wire where the harness routes along the rear wheelhouse or trunk area
Typical repair costs for C1467 range from $150 to $700, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Rear dampers locked at maximum firmness reduce rear axle compliance, which can cause the rear end to feel skittish on rough surfaces. While not an immediate safety concern, reduced rear tire contact patch adaptability may slightly affect braking stability on uneven roads.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1467 to identify the root cause.
