How to Test a Trailer Where It Sits With the Inspector 930 Professional Mobile Inspection Package
Not every trailer can be positioned conveniently beside a diagnostic tester. Some are parked outside, lined up in a crowded yard, or located in a shop where moving equipment creates extra work.
The Inspector 930 Professional Mobile Inspection Package is a mobile trailer inspection system built for those situations. It combines the Inspector 930 with two 20-foot air lines and a 20-foot 7-way cable, giving one technician added reach to test trailer lighting, electrical, ABS, brake, and air systems without moving the trailer closer to the tester.
What Is the Inspector 930 Professional Mobile Inspection Package?
The Inspector 930 Professional Mobile Inspection Package is a complete mobile trailer inspection system designed for longer trailers and hard-to-reach testing locations.
The package combines the Inspector 930 trailer diagnostic system with two 20-foot air lines and a 20-foot 7-way cable. These extended connections allow technicians to bring the testing equipment to the trailer instead of repositioning the trailer around shorter connections.
The package includes:
• Inspector 930 trailer diagnostic system
• Android tablet
• Two 20-foot air lines with gladhands
• One 20-foot 7-way cable
• Two-stage air filter regulator
• Pre-installed quick-disconnect fittings
The system arrives equipped for trailer testing, helping technicians avoid piecing together multiple tools and accessories.
Why Does Extended Reach Matter?
Trailer maintenance does not always happen under ideal conditions. A trailer may be parked along a fence line, outside the shop, in a crowded service bay, or beside other equipment that makes repositioning difficult.
The Professional Mobile Inspection Package provides longer connections for those environments. Its 20-foot air lines and 7-way cable allow one technician to reach trailers that may be difficult to connect using standard 8-foot lines.
This additional reach can help maintenance operations:
• Test longer trailers and hard-to-reach equipment
• Reduce unnecessary trailer repositioning
• Perform testing without connecting a tractor
• Keep electrical, ABS, brake, and air testing within one process
• Allow one technician to control the inspection
The technician can spend less time arranging the test and more time determining the condition of the trailer.
What Trailer Systems Can the Inspector 930 Test?
The Inspector 930 is an all-in-one trailer diagnostic system for compatible 7-way trailers. It simulates tractor electrical output and supplies service and emergency air, allowing technicians to perform testing without using a tractor as the test source.
Electrical and Lighting Systems
The Inspector 930 can operate all seven electrical circuits and display voltage and current draw in real time. It helps technicians identify electrical problems such as opens, shorts, cross-wires, and ground faults.
Technicians can also check trailer lighting, turn signals, and brake circuits under load.
Trailer ABS Systems
The Inspector 930 communicates with major trailer ABS ECUs, including WABCO, Bendix, Haldex, and GEN2.
Technicians can read and clear fault codes, view ECU information, test wheel-speed sensors, and receive diagnostic information without manually deciphering blink codes. Lite-Check also provides ABS coverage updates for the life of the unit.
Air and Brake Systems
The system supplies and controls service and emergency air for trailer testing. Technicians can use it to check air pressure, leaks, restrictions, and other pneumatic conditions.
Remote tablet operation allows one technician to control these functions while walking around the trailer.
How Do the Inspector 930 and Sentry Work Together?
The Inspector 930 performs the physical testing and captures diagnostic information. Sentry is Lite-Check’s software layer for inspection records and reporting.
When paired with Sentry on the included Android tablet, the Inspector 930 can support digital PM, DOT, and custom inspection records. Reports can be stored, shared, or exported as PDFs, helping maintenance teams turn diagnostic results into organized records.
The difference is simple:
• Inspector 930 tests and diagnoses the trailer.
• Sentry documents and reports the results.
Together, they help connect trailer testing with maintenance documentation. Sentry capabilities and service terms may depend on the selected configuration or subscription.
Bring Complete Diagnostics to the Trailer
A trailer diagnostic system should fit the way maintenance work actually happens.
The Inspector 930 Professional Mobile Inspection Package gives technicians the reach to inspect trailers throughout the shop or yard while keeping electrical, ABS, brake, and air testing within one system.
With 20-foot connections, remote operation, and an included Android tablet, the package helps one technician test the entire trailer where it sits.
