Week 4: Maserati Mischief

Apr 26, 2019

This week a Maserati GranTurismo caught my attention. The gorgeous silver car got tapped on the bumper while waiting at a stop light. After this unfortunate incident, the airbag light turned on but the airbags did not deploy. Even though the airbags didn’t go off, the impact was strong enough to cause the seatbelts to lock up.When the vehicle arrived at Corsa Motors, James plugged the car into a special computer, called Leonardo, to perform the diagnostic. Leonardo showed us that there was a seatbelt module error and after further investigation, James found that the driver’s seat belt was broken. It is important to make sure that the other seatbelts are in good condition to ensure the highest safety so James proceeded to ensure the other seatbelts were not damaged. However, this was not an easy task. In order to examine the rear seatbelts the rear seats had to be removed from the car. The seat belts are then checked with a multimeter and then again put through another diagnostic test on the Leonardo computer. Thankfully, all the other seatbelts were in tact.

Unfortunately, there was another problem with the Maserati. The accident made the parking sensor fall into the bumper. To fix this issue, the bumper cover had to be dislodged and then a new sensor installed.

It was really interesting for me to see the engineering behind the Maserati GranTurismo.

I couldn’t even imagine that in order to check the functionality of the seatbelt the entire interior of the car has to be removed. The same goes for the McLaren I talked about the passed few weeks. After waiting for three weeks, we finally received the shift position sensor for the McLaren P12. The shift position sensor is a computer that takes in the driver’s input from the paddle shifters and then it changes the gear. Now, in order to replace this part, we have to take the engine out of the car, take apart the gear shifting mechanism, replace the part and then put everything back together. The whole engine has to come out and the entire shift solenoid assembly has to be dismembered just to replace the shifting computer.

I can’t wait to share what James will be working on next week.

    Wow this sounds super interesting, Peter! I never knew that certain aspects of car safety could be determined through computer programming. I look forward to see your future findings.
