What Does C1784 Mean?
The ICCS2 passenger-side right damper output circuit has a short to battery voltage. The suspension control module is detecting unwanted battery voltage on the right damper control wire. This disables adaptive damping on that corner, forcing it into a default fixed setting. The driver may notice uneven ride quality and a suspension or ride control warning on the dash.
Common Causes
35%
Chafed or damaged wiring harness shorting right damper control wire to power
30%
Faulty right damper solenoid with internal short to supply voltage
20%
Corrosion or water damage at the damper solenoid connector
10%
Suspension control module output driver failure on right channel
5%
Harness routed against positive power source wire
Diagnostic Steps
1
Disconnect the right damper solenoid connector and measure voltage on the module-side signal pin with key on — should not show a constant battery voltage. Constant 12V+ with the solenoid disconnected confirms a short to B+ in the wiring.
2
Measure the right damper solenoid coil resistance (spec typically 3-8 ohms). Also check insulation resistance between coil terminals and the solenoid housing — should be >10K ohms.
3
Trace the wiring harness from the ICCS module to the right damper, inspecting for insulation damage, pinch points near the shock tower, and contact with adjacent power wiring.
4
Clean the damper solenoid connector, inspect for pushed-back pins or corrosion, and apply dielectric grease before reconnecting.
5
If all wiring tests normal, swap the left and right damper solenoid connectors at the module (if pin-compatible) and clear codes — if the code follows the connector swap, the issue is in the harness or solenoid, not the module.

Typical repair costs for C1784 range from $200 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Drivable, but the right-side adaptive damping is disabled. Ride and handling will be unbalanced. Avoid spirited driving and lane-change maneuvers at highway speed until the suspension system is fully operational.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1784 to identify the root cause.
