Question 43Electricity & Electronics - 1st Asst/Chief

The correct answer is C) Replace the CPU assembly. The reasoning is that when the fault code 41 (SPEED LOG ERROR) is displayed, it indicates an issue with the CPU (central processing unit) of the adaptive digital steering system. The CPU is responsible for processing and interpreting the data from the speed log, and if there is an error in the CPU, it can lead to the displayed fault code. Replacing the CPU assembly would be the last corrective action, as it is the most complex and comprehensive solution to address the underlying issue. The other options are incorrect because: A) Replacing the ADS (Adaptive Digital Steering) assembly may not be necessary if the issue is specifically with the CPU. B) Checking the connection may help identify the problem, but it does not directly address the CPU issue. D) Checking the message string output by the source may provide additional information, but it does not directly solve the CPU-related problem.
