Quizplus · Accepted Answer

Technician A is correct that a DMM (Digital Multimeter) and a scan tool are important tools needed to diagnose a computer-controlled transmission. These tools provide accurate readings and can help identify specific faults or codes stored in the transmission's control module.

Technician B is incorrect because a simple test light cannot provide the same level of accuracy as a DMM or scan tool when diagnosing circuits in a computer-controlled transmission. Using a test light alone can lead to misdiagnosis and may even cause further damage to the transmission's control module.
