What it means
Active air dam supply voltage below expected range. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
At a glance
- Usually lights the ABS or stability-control warning light
How it works
The active air dam is a movable panel that helps manage airflow under the vehicle, and its actuator receives power through a supply circuit. The control module monitors that supply and sets C062E when the voltage is lower than expected, which can prevent the air dam from operating.
Common causes
Most likely first.
- Supply wiring fault
- Connector pins corroded - high contact resistance
- Harness chafing through insulation
Symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
How to diagnose it
- Read the code and freeze-frame data with a scan tool that can access the reporting module, and check whether the low-voltage fault is current.
- Inspect the active air dam supply wiring and connectors for chafing, water entry, corrosion, or a pin pushed back into the connector.
- With the fault present, monitor the supply reading while gently moving the accessible harness to see whether it changes.
- Check supply voltage and voltage drop at the air dam connector under the conditions specified by the manufacturer.
- If the supply wiring and connections pass, trace the circuit toward its power source and module for an open or excessive resistance.
Common fixes
- Repair chafed or broken supply wiring to the active air dam.
- Clean and secure corroded or loose connector terminals, replacing damaged terminals or seals.
- Restore a pushed-back connector pin and verify it holds contact.
- Repair the supply connection or wiring fault identified by voltage-drop testing.
Can I keep driving?
This code usually affects active airflow management rather than basic braking, but the listed brake and stability warnings should be taken seriously if they are present. Avoid relying on the air dam to move correctly until the supply fault is fixed.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
