Modern heavy-duty trucks run on a network of electronic control modules: engine, transmission, brakes and ABS, aftertreatment, body and more. When one of them sees something out of range, it stores a fault code and often lights a warning on the dash. Computer diagnostics means reading those codes, understanding how they relate to each other, and testing the circuit, sensor or component behind them.
That last part matters. A code tells you where to start looking; it doesn’t name the broken part. A sensor code can come from the sensor, the wiring, a corroded connector, or a real problem the sensor is only reporting. Checking before replacing is what keeps a diagnostic visit from turning into a pile of parts you didn’t need.
Bawa’s has been working on trucks and trailers in Dallas since 2011. Plenty of our warning-light calls come in after the first shop, or a truck stop, couldn’t sort the problem out. One driver wrote on Google that his ABS had gone out, that TA and Love’s couldn’t fix it, and that we got him back on the road.
We can’t promise every fault is a quick one. What we do is find the real cause, tell you what we found in plain words, and let you decide what happens next.

Tell us the truck, the light and any codes you’ve seen. Call +1 (214) 400-4228.
Heavy-duty trucks first, with trailer ABS and electrical faults handled too.
We read the engine fault codes, then test the sensors, wiring and connectors behind them. Derates, rough running and power loss are all fair game.
ABS and brake lights on tractors and trailers. Wheel speed sensors, tone rings, wiring and the ABS module get checked in turn.
Intermittent lights, blown fuses, bad grounds and charging problems. We trace the circuit instead of swapping parts until it stops.
Dash lights, derates and limp modes. We read what the truck is reporting, explain it, and tell you how urgent it is.
A fault code is a starting point. We confirm the cause with testing before we recommend a replacement.
We tell you what we found, what it means for the truck and what can wait, in words you can actually use.

Repairing commercial trucks and trailers here since 2011.
Three steps, no surprises.

We explain what we found and what it costs. The repair goes ahead once you approve it.
Generally, a red warning means stop and check now, and an amber one means the truck has found a problem that needs attention soon. Either way, the light only tells you something is wrong, not what. The stored fault code is where the real answer starts.

Abs went out and after going to TA and Loves they could not fix the issue. BAWAs came in clutch. Got me back on the road. Turning tires, and making money.
