Here are some expanded answers to the quick quiz questions. Don’t forget to take a look at how you’re doing on the leaderboard at the bottom of the page.

QUESTION 1 ANSWER

When is a TIPS case required?

• When the dealer has exhausted all technical diagnosis and resources in the workshop ✅
• 12 V battery replacement
• Rental request
• For Roadside support or Customer Care

The following cases all require a TIPS Case:

• A Tips case is required when a dealer has exhausted all technical diagnosis and resources in the workshop.
• Major component replacement and aggregate repairs.
• When a TIPS – GI document requires a TIPS case to be created.
• Requested by Warranty and Maintenance department.
• Product liability cases – Fire and
• Accidents where clients claim product failure or injury.

QUESTION 2 ANSWER

When performing compression tests on combustion engines equipped with starter systems such as ISA or ISG, what is the correct procedure to initiate the test?

• Use the Xentry diagnostic tool to initiate the compression test and follow the special procedures ✅
• Start the compression test manually without any software.
• Perform the test using a standard compression gauge only.
• Initiate the compression test directly from the engine control unit without any software guidance.

For modern combustion engines equipped with advanced starter systems like ISA (Integrated Starter Alternator) or ISG (Integrated Starter Generator), performing compression tests requires precise control and communication with the engine management system. These starter systems often interact with the engine control unit (ECU) in ways that a traditional manual compression test or standalone gauge cannot fully accommodate.

QUESTION 3 ANSWER

When diagnosing engines exhibiting symptoms such as over temperature, rough running, or misfires, and a TIPS case is opened, what is the required next step regarding compression testing?

• Perform a mechanical compression test as specified in the WIS compression specification document ✅
• Conduct an electronic compression test using standard diagnostic tools.
• Perform a visual inspection only and ignore compression testing.
• Replace the engine components immediately without testing.

Mechanical compression testing is crucial to assess the mechanical condition of the engine and pinpoint issues such as worn piston rings, valves, or head gasket failures.

QUESTION 4 ANSWER

For brake-related TIPS cases, which of the following are required to properly document and diagnose the issue?

• Clear pictures of brake discs and pads in a removed state, videos illustrating any brake noise, and brake pad and disc measurements with minimum specifications ✅
• Only written descriptions of brake noise are necessary.
• Just the measurements of brake pads and discs without any visual evidence.
• Replacement of brake components without any documentation or evidence.

When dealing with brake-related TIPS (Technical Information and Problem Solving) cases, thorough and accurate documentation is critical to correctly diagnose the problem and justify any repairs or warranty claims. This includes picture and video evidence

QUESTION 5 ANSWER

For electrical system TIPS cases, which of the following are the correct documentation and attachment requirements?

• Use attachments directly from the diagnosis device, include graphs directly from Xentry in colour, ensure connection points are visible in images of measurements, and show settings in scope measurements ✅
• Attach scanned copies of handwritten notes and black-and-white graphs.
• Only verbal descriptions of measurements are needed, no images required.
• Attach images with no need to show connection points or scope settings.

The correct documentation for electrical system TIPS cases involves using direct digital attachments, clear colour graphs, visible connection points, and full oscilloscope settings to ensure comprehensive, accurate, and professional case documentation.
