ABS Outlet Valve Coil RF Circuit Failure
Chassis Chassis/Safety ABS Solenoid Coil 🔴 Serious — Stop or limit driving
💬
What This Actually Means
In plain language — no jargon

The ABS system's right-front outlet valve coil has an electrical problem preventing it from working properly. Think of it like a solenoid switch that's broken—the ABS pump can't release brake pressure when needed.

Embedded Systems Insight
What the ECU/ECM is actually computing

The ECU monitors the coil resistance and voltage across the right-front ABS outlet valve solenoid. It expects a specific resistance range when the valve is commanded on or off. If resistance is out of range or the circuit shows open/short conditions, the fault is logged.

Voltage & Parameter Thresholds

Parameter Normal Range Fault Condition
Coil Resistance 6-14 ohms Open circuit (∞ ohms) or shorted (<1 ohm)
Solenoid Voltage 11-14V when commanded <2V or no voltage change detected

Diagnostic & DIY Fix Guide
Check these in order — from cheapest to most complex
1
ABS wiring harness connector at RF wheel
Inspect and clean coroded connectors; reseat the connector firmly to restore electrical contact.
2
ABS outlet valve solenoid coil (RF)
Test coil resistance with a multimeter; replace the solenoid if resistance is out of spec.
3
ABS module wiring harness
Check for chafed or pinched wires between the ABS module and RF wheel; repair or replace damaged sections.
