Brake System Warning (Red)
Red circle with exclamation mark or “BRAKE SYSTEM FAULT” message
🚨 IMMEDIATE SAFETY CONCERN
This warning indicates complete or partial brake system failure. Your vehicle may have significantly reduced braking ability or complete brake failure. Proceed with extreme caution.
Diagnostic Tree for Brake System Warnings
Step 1: Initial Safety Check
- Brake Fluid Level: Check reservoir level (engine running for accurate reading on electronic systems)
- Pedal Feel Test: Note if pedal is soft, hard, or travels to floor
- Visual Inspection: Check for fluid leaks at wheels, under master cylinder, and along brake lines
Step 2: Electronic System Diagnosis
- ABS Module Scan: Use JLR SDD/Pathfinder to read ABS/DSC fault codes
- Wheel Speed Sensor Test: Check all four wheel speed sensors for proper operation and alignment
- Brake Pressure Sensor Test: Test pressure sensors in ABS module
- Yaw Rate Sensor Calibration: Recalibrate if DSC system fault detected
Range Rover Specific Brake System Components
The Range Rover Vogue uses a sophisticated brake-by-wire system in later models. Key components include:
🔄 iBooster System
Electronic brake booster that provides consistent pedal feel. Common fault: Position sensor failure.
⚡ ESP Hev II Module
Electronic Stability Program module controlling ABS, DSC, CBC, and brake pressure distribution.
🎯 Dynamic Response Braking

Advanced Diagnostic Protocol
Phase 1: Code Retrieval & Analysis
- Professional Scanner Required: Use Autel MaxiSys, Snap-on Zeus, or JLR SDD for manufacturer-specific codes
- Freeze Frame Data: Capture engine parameters at moment of fault
- Pending vs. Confirmed Codes: Differentiate between intermittent and active faults
- Mode $06 Data: Access manufacturer test results for comprehensive analysis
Phase 2: Component & System Testing
- Live Data Monitoring: Monitor fuel trims, O2 sensor activity, MAF readings, and injector pulse width
- Relative Compression Test: Using scan tool to identify weak cylinders
- Fuel Pressure Testing: Mechanical gauge testing of low and high pressure systems
- Smoke Testing: For vacuum and intake leaks (common on 5.0L V8)
Phase 3: Verification & Repair Validation
- Component Actuation Tests: Command solenoids, valves, and actuators via scan tool
- Adaptation Reset: Clear adaptations after major repairs for proper relearn
- Road Test Verification: Monitor parameters under actual driving conditions
- Emission Readiness Monitor Check: Verify all monitors complete after repair
Suspension System Warning

⚠️ AIR SUSPENSION SYSTEM CRITICALITY
The Range Rover’s Electronic Air Suspension (EAS) is complex and failures can result in the vehicle lowering to bump stops, creating a dangerous driving condition and potential component damage from driving at incorrect ride height.
EAS Diagnostic Procedure
1 System Initialization & Leak Detection
- Start vehicle and listen for continuous compressor operation (indicates major leak)
- Use soapy water solution to check all air lines, valve blocks, and bag connections
- Check compressor drain valve for proper sealing (common failure point)
- Monitor vehicle height over 30 minutes to detect slow leaks
2 Component Testing & Analysis
- Compressor Test: Check amp draw (should be 15-30A) and output pressure (should reach 150-180 PSI)
- Height Sensor Calibration: Use diagnostic tool to calibrate all four corner sensors
- Valve Block Test: Command each valve individually to isolate circuit failures
- Dryer Desiccant Check: Replace if compressor runs excessively or system is slow to adjust
3 System Calibration & Final Verification
- Perform full ride height calibration using factory diagnostic software
- Test all suspension modes (Access, Normal, Off-Road, Extended)
- Verify system holds pressure overnight without significant height drop
- Clear fault memory and verify no codes return after test drive
EAS Repair Cost Breakdown
| Component | Parts Cost (OE) | Parts Cost (Aftermarket) | Labor Time | Total Cost Range |
|---|---|---|---|---|
| Air Spring (per corner) | £280 – £450 | £180 – £300 | 1.5-2.5 hours | £350 – £750 |
| Compressor Assembly | £450 – £750 | £300 – £500 | 1-1.5 hours | £550 – £950 |
| Valve Block Assembly | £300 – £500 | £200 – £350 | 1-1.5 hours | £350 – £700 |
| Height Sensor (each) | £120 – £200 | £80 – £150 | 0.5-1 hour | £150 – £300 |
| Complete EAS Overhaul | £2,500 – £4,000 | £1,800 – £3,000 | 8-12 hours | £3,500 – £7,000 |
