Exam 34: Ests and Siss

On a standard J1939 data link connector (DLC), which terminal assignment represents J1939 CAN hi or positive?

On a J1587/1708 data link connector (DLC), which terminal assignment represents J1587 dominant high or positive?

When a DMM is switched to diode test mode, how much voltage is driven through the diode being tested?

Technician A says that the FMIs added to qualify DTCs in 2007 were numbered between 15 and 31. Technician B says that the post-2007 FMIs were added to identify imminent failures in components and circuits. Who is correct?

Which of the following is true regarding any controller with a SA on the data bus?

When using a DMM to test for current, how should the test leads be inserted into the electrical circuit?

Technician A says that some earlier generation OEM communications adaptors (CAs) using RP1210 protocols had embedded blocking features so that they could only communicate with one OEM system. Technician B says that any device with a SA on the data bus has some computing capability. Who is correct?

Technician A says that all engine OEMs supported both J1587 and J1939 chassis data buses up until 2010. Technician B says that post-2010 Cummins and DDC engine electronics no longer support J1587 bus communications. Who is correct?

What EST do Navistar International recommend you use to interact with their chassis systems?

What does the acronym EST represent in the truck service industry?

Technician A says that RAPIDO software should be used in conjunction with DAVIE. Technician B says that any RP1210 CA can be used to network with any Paccar data bus. Who is correct?

Technician A says that it is important to memorize the numeric values of all the key engine SIDs in order to effectively troubleshoot modern diesel engines. Technician B says that an advantage of the post-2007 FMIs is that they can identify possible imminent failures. Who is correct?

When testing a potentiometer type throttle position sensor (TPS) with a DMM set to V-DC which of the following should be true?

Technician A says that the monitored fields in HD-OBD relate either directly or indirectly to emissions controls. Technician B says that engine misfire will be a monitored field. Who is correct?

Which of the following devices can be used on the PC to connect with a truck data bus?

A highway truck crane is equipped with two engines, one for propulsion and the other to run the auxiliary equipment. What is the numeric SA of the auxiliary engine controller on the J1939 bus??

When checking test lead resistance on a DMM, the reading is a little over 1 ohm. Which of the following is probably true?

When a diode is tested using a DMM set in diode test mode, and the reading indicates continuity in both directions:

Which of the following would indicate an open circuit if displayed on a DMM while checking resistance?

On a J1962 DLC, which socket is CAN-Hi?
