Check engine light, air suspension warning, Terrain Response fault, or something you can't quite describe — we use professional-grade diagnostic equipment to read every system in your Jaguar or Land Rover accurately and completely.
Our Diagnostic Approach
Professional Equipment. Honest Assessment.
We use professional-grade diagnostic tools that cover the full range of Jaguar and Land Rover systems — fault codes, live data, bi-directional module functions, and service resets. While we don't use JLR's proprietary dealer-only software, our equipment provides comprehensive coverage of all JLR platforms and allows us to accurately diagnose the vast majority of issues these vehicles present. We tell you what we find and what it means — no guesswork, no parts-cannon approach.
Full fault code reading and live data across all engine management systems. Misfire diagnosis, fuel system faults, emissions failures, sensor diagnosis, and turbocharger performance on petrol and diesel engines.
ZF and Aisin transmission fault codes, adaptive data reset, transfer case diagnosis, Haldex AWD system faults, and torque converter diagnosis across all JLR drivetrain configurations.
Compressor function testing, air spring leak detection, height sensor calibration, valve block diagnosis, and suspension control module fault reading on Range Rover, Discovery, and Jaguar XJ/XF air suspension systems.
Terrain Response system fault diagnosis, transfer case electronic faults, differential lock system diagnosis, and Hill Descent Control issues on all Land Rover four-wheel-drive platforms.
Body Control Module faults, lighting system diagnosis, window and door module issues, InControl system faults, and multi-module communication errors that cause seemingly unrelated symptoms.
ABS, DSC, and traction control fault diagnosis, electronic parking brake faults, airbag and SRS system fault reading, and stability control module diagnosis.
Dual-zone and quad-zone climate control faults, refrigerant system diagnosis, blower motor faults, and temperature control module issues.
Oil service indicator reset, brake pad wear sensor reset, battery registration, throttle body adaptation, and transmission adaptive reset after fluid service.
Battery health testing, alternator output diagnosis, start/stop system faults, and parasitic drain diagnosis on JLR's complex electrical architecture.
We connect to every module in your vehicle and pull all stored and pending fault codes — not just the ones triggering a warning light.
Fault codes tell us where to look. Live data tells us what's actually happening — sensor values, pressures, temperatures, and system responses in real time.
We verify the actual root cause before recommending any repair. We don't replace parts based on codes alone — we confirm the failure first.
You get a plain-English explanation of what we found, what caused it, and exactly what's needed to fix it — with a written estimate before any work begins.
Don't guess — get it diagnosed correctly. Located at 8926 Broadway, San Antonio.
