"Shut that door!" – Another top tip from Professor Rob

Shut That Door!

Vehicle diagnostic checking – always remember to shut the doors first or else there is a real chance your diagnostic tester won’t communicate with the car you are connected to.

Many vehicles (particularly Germanic ones) will restrict high level ECU access with the doors open or if the interior lights are on. Basic entry level EOBD readers pick codes from around the ECU core data..…but to go right into an ECU at a higher level using OEM type communication protocols – then many ECU’s only exchange data with the doors shut & interior lights off – so always remember to Shut That Door!

Steering Sensors and the vital need to reset them

Steering Wheel Calibration

When visiting a garage recently, Prof Rob arrived as the owner was working on a Citroen C4 that had a problem with its steering. Most new cars today have a version of stability control or ESP and for this to work correctly after any repair, it is vital that the steering position sensor is reset. 

It was positive to see that the owner reset the sensor as soon as he had fixed the steering problem – avoiding the risk of any danger to the cars stability once the owner had driven away. As any vehicle ECU relies on accurate information to safely control the car – resetting the steering sensor is easily done – so don’t forget………..reset!
