Question 44Electricity/Electronics - 1st Asst/Chief70% to pass
Using the trouble analysis chart and faults table provided in the illustrations, if the adaptive digital steering system was malfunctioning, and the fault code 42 (SPEED LOG ERROR) is displayed, what corrective action should be performed FIRST? Illustration EL-0197 and EL-0198
AI Explanation
The correct answer is D) Check speed log source (log data strings from source).
This is the correct answer because when the fault code 42 (SPEED LOG ERROR) is displayed, the first step is to check the speed log source to ensure that the log data strings being received by the adaptive digital steering system are valid. This helps isolate the issue to the speed log itself, rather than the steering system components.
The other options are incorrect because replacing the DC/DC assembly or CPU assembly would not address the root cause of the speed log error, and checking the wire connections is a secondary step after verifying the data source.
