Causes

Open or short in wiring to left front inlet (apply) solenoid
Poor or corroded connector at HCU or ABS module
Faulty left front inlet solenoid (stuck open/closed or internal short)
Faulty ABS/HCU hydraulic unit
Faulty ABS/ESC control module
Low battery voltage or poor battery/charging system

Symptoms

ABS and/or ESC warning lamp illuminated
Possible reduction or loss of ABS function at left front wheel
Brake feel may be altered under ABS operation (pulsation or firm pedal)
Traction control interventions may be disabled or reduced
One or more additional ABS or wheel-related codes present
Stored freeze-frame data showing event conditions

What to check

Read and record all ABS/ESC codes and freeze-frame data with a capable scan tool
Verify battery voltage and charging system before and during tests (should be ~12.6 V resting, ~13.5–14.8 V running)
Visually inspect HCU/ABS connector and left front wiring harness for damage, corrosion, or water intrusion
Perform wiggle test on wiring/connectors while monitoring live data or resistance
Measure resistance of the left front inlet solenoid (compare to manufacturer spec or the matching right-front channel)
Check for continuity to ground and proper 12 V supply at the solenoid connector when activated

Signal parameters

Activation voltage: ~12 V supply when solenoid is commanded (verify with scan tool output command)
Typical solenoid resistance: often between 5–30 ohms (vehicle-specific — confirm factory spec)
Control signal: pulse-width or duty-controlled by ABS module during modulation (varies with braking event)
No continuity to ground (open circuit) or near-zero resistance (short to ground) indicate wiring/solenoid fault
Live data: command state vs feedback (if module reports expected vs actual status)

Diagnostic algorithm

Connect a diagnostic scan tool that reads ABS/ESC modules. Record C0010 plus any other stored or pending codes and freeze-frame data.
Check battery voltage and ensure good ground. Low voltage can create false faults—restore normal charging if needed and clear codes to re-test.
Visually inspect the ABS/HCU harness, left front branch, and connectors for damage, corrosion, or water ingress. Repair any obvious issues.
With ignition ON (engine off), disconnect the HCU harness and measure resistance of the left front inlet solenoid across its pins. Compare to the right front solenoid and to factory spec.
Backprobe the HCU connector and command the left front inlet solenoid ON using the scan tool (if function available). Verify the module outputs correct voltage/pulse and measure current draw. No output suggests module fault.
Check continuity between the HCU and the solenoid connector; look for opens, high resistance, or shorts to ground/power.
If wiring and connector are good but solenoid resistance is out of range or solenoid does not actuate when powered, replace the left front inlet solenoid (or valve pack if serviceable).
If solenoid and wiring test good but fault persists and module does not command or reports internal subfault, consider ABS/HCU replacement or refurbishment. Check for technical service bulletins (TSBs) before replacement.
After repairs, clear codes, perform system bleed if hydraulic work was done, and perform road test/ABS activation to confirm the fault does not return.

Likely causes

Damaged/loose connector or wiring to the left front inlet solenoid
Failed left front inlet solenoid
Corroded or intermittent pin at the ABS/HCU connector
Faulty ABS hydraulic unit (valve pack)

Fault status

⚠️ Status

ABS control module reports a subfault on the left front inlet control circuit/valve. Investigate wiring, connector, solenoid, HCU, and power/ground.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 1-2 hours
