Technician A says, if the speedometer is not operating and the BCM and/or cluster module passes the self-test, the fault may be in the VSS circuit. Technician B says if the speedometer works but the odometer does not, the vehicle speed sensor likely is the problem. Who is correct?

Technician A is correct because if the speedometer is not operating but the Body Control Module (BCM) and/or cluster module passes self-tests, it indicates that the issue might be elsewhere, such as in the Vehicle Speed Sensor (VSS) circuit. Technician B is incorrect because if the speedometer works but the odometer does not, the problem is more likely within the instrument cluster itself rather than the vehicle speed sensor, as the VSS is functioning enough to operate the speedometer.
