2020 Ford Expedition – Cooling Fan & A/C Diagnosis 🔧

Vehicle came in with the cooling fans not operating, affecting proper A/C operation.

Using bidirectional controls, the PCM was able to command both Low and High Fan Speed, but the cooling fans did not respond. Further electrical testing revealed a blown 10A fuse supplying several related control circuits.

Instead of simply replacing the fuse, we tested the circuit to determine why the fuse had failed.

During the inspection, we found that the vehicle had previous collision repairs and the Active Grille Shutter wiring had been modified with an incorrect connector from another vehicle. The connector was wired incorrectly, causing the circuit to short and blow the fuse.

We identified the correct power, ground, and LIN communication circuits, restored the original connector and wiring configuration, replaced the fuse, and performed final active tests.

✅ Cooling fans operating correctly
✅ Low & High speed control restored
✅ Active Grille Shutter wiring corrected
✅ A/C system operation restored

A blown fuse is not always the problem — sometimes it’s the clue that leads you to the real problem.

🔧 2017 Chrysler Pacifica – Diagnóstico electrónico + ADAS

Esta Pacifica llegó con diferentes problemas eléctricos y advertencias en el tablero. En lugar de comenzar reemplazando componentes, realizamos pruebas para identificar cada falla.

🌡️ Sensor de temperatura ambiente

La lectura de temperatura exterior era incorrecta. Verificamos el sensor midiendo su resistencia y comparamos su comportamiento con la temperatura ambiente.

Después utilizamos un simulador de resistencia en el circuito para comprobar la respuesta del módulo y el dato mostrado por el scanner. Esto nos permitió confirmar que el cableado y la interpretación del módulo respondían correctamente y que el sensor estaba fuera de especificación.

Se instaló un sensor nuevo y verificamos aproximadamente 3.43 kΩ, además de confirmar en datos en vivo que la temperatura exterior volvió a responder correctamente. ✅

📡 ACC / Forward Collision Warning

También encontramos el código C14A4-00 – Sensor Adjustment Required.

Durante la inspección descubrimos daños previos en la parte frontal: el montaje del radar ACC estaba roto y el sensor no estaba firmemente sujeto.

Realizamos el procedimiento de ACC Radar Calibration / Auto Alignment. La calibración fue aceptada y, después de un ciclo de ignición, las advertencias relacionadas con ACC/colisión desaparecieron. ✅

Sin embargo, se informó al cliente que el radar necesita quedar mecánicamente fijo en su posición correcta para que la calibración permanezca confiable.

🔍 Diagnosticar primero. Reemplazar piezas solamente cuando las pruebas lo justifican.

🔧 2019 RAM 1500 5.7L — Active Grille Shutter Diagnosis

Vehicle came in with DTC P1D73 – Active Grille Shutter Performance.

During diagnosis, we verified the AGS electrical circuit, power, ground, and LIN communication. The actuator was able to perform its initialization cycle, but the fault continued to return when operating the grille shutters.

Further testing showed that when the mechanical load from the shutters was removed, the actuator completed its operation without the P1D73 returning, pointing us toward a mechanical/component compatibility issue rather than a communication failure.

After removing and inspecting the grille shutter assembly, we discovered that the unit installed on the vehicle was an aftermarket assembly with no identifiable OEM part number. We also found damaged/broken components in the shutter mechanism.

Using the vehicle VIN, the correct Mopar assembly was identified as P/N 68405073AE. A replacement assembly supplied for testing was P/N 68104713AF, which is a different application and even uses a different connector, so it was not installed.

Diagnosis: Active Grille Shutter assembly/actuator performance issue associated with the incorrect aftermarket assembly.

Correct OEM-spec assembly recommended before final verification.

2024 BMW 228i xDrive – EPS / Steering Diagnosis

Vehicle came in with a heavy steering feel, steering clunk, and abnormal Lane Departure Assist behavior following a previous front-end collision.

No active EPS or DSC fault codes were present, so further testing was performed.

Using live data and current measurements, we verified that the EPS torque/position inputs were responding and the electric steering motor was operating under load.

A mechanical clunk was still present even with the EPS system powered off. Using vibration/noise sensors and an oscilloscope, the impact was traced directly to the steering rack assembly, while the tie rods showed significantly less vibration.

Diagnosis: Internal mechanical fault/play in the electric steering rack.

The steering rack was replaced and the vehicle received a complete alignment. After repairs, the customer confirmed that the steering and vehicle handling returned to normal.

Another example of why proper testing matters: no guessing, no unnecessary parts — test, verify, repair.

Mercedes-Benz GLK350 – SRS & Panoramic Sunroof Diagnosis

Vehicle came in with SRS/Airbag and panoramic sunroof faults after previous collision repairs.

🔧 SRS Diagnosis:
Multiple airbag, seat belt pretensioner and pyrofuse fault codes were stored. Instead of replacing parts based on codes alone, we checked the actual SRS circuit data.

✅ Driver & passenger airbag circuits tested within specification
✅ Seat belt pretensioner circuits tested within specification
✅ Pyrofuse circuit tested within specification
✅ Incorrect/missing VIN detected in the SRS control module
✅ Correct vehicle VIN was programmed, eliminating the VIN fault

After programming, two internal SRS control module faults remained active, confirming that further module-level repair/programming is required rather than replacing airbags or pretensioners unnecessarily.

🔧 Panoramic Sunroof Diagnosis:
The sunroof module reported loss of calibration. Testing showed that the motor attempts to operate, but only the left side of the glass moves while the right side remains stationary, indicating a mechanical drive/rail/cable issue preventing calibration.

Diagnosis before parts. Test, verify, then repair.

2017 Honda Accord / ABS-VSA Diagnostic
Vehicle came in with intermittent ABS, VSA, and Power Steering warning lights. We found DTC 123 - 11 - VSA Solenoid Valve Malfunction, along with multiple communication codes related to the VSA module.
Diagnostic testing includes:
- Power and ground circuits tested under load.
-ABS/VSA connector and wiring inspection.
-CAN BUs network analysis.
-Communication testing with the VSA module.
Power and Ground circuits tested good. The CAN bus network operated normally with the VSA module disconnected, but communication became unstable when the VSA module was connected and communicating on the network.
Diagnosis: Internal ABS/VSA module failure.
Repair: Replace the ABS/VSA modulator assembly and perform the required initialization/calibration procedure.
