The business is also furnished with modern diagnostic equipment and technical information systems, ensuring that Adelaide Luxury Motors is positioned as a leader in excellence and technology - ultimately ensuring a first-class customer experience.
Having received a 2015 model year Jaguar in his workshop, in a non-start state, Rob Addabbo conducted preliminary diagnosis tests.
Using his Autologic device Rob established that there was one module showing a fault. The fault displayed as:
B100D-87- COLUMN LOCK AUTHORISATION.
Part of Rob’s efficiency, cost and time saving processes in his workshop includes the use of AutologicLive. AutologicLive gives Rob daily access to OEM-trained master technicians who provide the step-by-step guidance all the way from diagnosis to full repair. Acting as his virtual team to give guidance on troublesome repair jobs, Rob increases efficiency in his workshop and drives down costs by reducing the time his technicians spend diagnosing complex vehicle faults.
Using his Autologic device, Rob sent a ‘support request’ to the Autologic team, via the push of a button on his device. This is a unique support request function, directly integrated into Autologic’s CRM, and enables technicians to submit a full vehicle data log of the exact fault and symptoms ready for one of Autologics’ OEM-trained master technicians to evaluate.
Based on the information provided, David Johnston, one of Autologic’s Jaguar OEM-trained master technicians, was able to contact Rob and provide the actions required to repair the fault.
David explained that in order to resolve the fault, Rob would need to re-establish communications with the immobiliser module.
He explained that the fault code meant that the Vehicle Immobiliser Control Module (VICM) and other control modules on the vehicle were not communicating with each other. The circuit most often used to communicate with is known as CAN bus (Controller Area Network bus communications).
David explained that the vehicle immobiliser control module is typically located behind the dash or inside the steering column. It receives inputs from other modules on the MOST bus communications system. These inputs allow the module to take control when the vehicle starts.
Rob was advised to:
Pull the connectors apart and carefully inspect the terminals inside the connectors.
Review to see if they look burned, or have a green tint indicating corrosion.
Use electrical contact cleaner and a plastic bristle brush if cleaning of the terminals is needed.
Leave to dry, and then apply electric silicone grease where the terminals contact.
Before connecting the connectors back to the VICM, Rob was advised to make a few voltage checks (using a digital volt-ohmmeter (DVOM);
Verify that there is power and ground at the VICM.
Use a wiring diagram to determine where the main powers and grounds come into the VICM.
Reconnect the battery before continuing, with the VICM still disconnected.
Connect the red lead of the voltmeter to each B+ (battery voltage) supply coming into the VICM connector and the black lead of the voltmeter to a good ground.
David explained that Rob should see a reading of battery voltage.
He then suggested that Rob;
Hook the red lead of the voltmeter to battery positive (B+) and the black lead to each ground circuit.
Next, to check the two communication circuits.
Locate the CAN B+ (or MSCAN + circuit) and CAN B- (or MSCAN – circuit).
With the black lead of the voltmeter connected to a good ground, connect the red lead to CAN B+. With the Key On, Engine Off, Rob should see about 0.5 volts (fluctuating slightly).
Connect the red voltmeter lead to the CAN B- circuit and that it should read approximately 4.4 volts (fluctuating slightly).
After following David’s guidance on how to re-establish communication with the immobiliser, the fault code was no longer present and Rob was able to return the vehicle to a working condition.
With everything in working order Rob was able to return the vehicle back to his customer in minimal time.
AutologicLive is a full diagnostic support service that provides workshop owners and technicians worldwide, like Rob, with a virtual team of OEM-trained master technicians, enabling the reduction of overhead costs, improved efficiency and customer satisfaction.
