Customer Questions and Answers
Question: I recently purchased a GBZ-FD40 Maintenance Module from your store. I just have questions before I start installing.
Question:What must be done first before installing the FD4O Control Module?
Answer: Batteries fully charged. Disconnect any other devices. Turn everything off.
I purchased these following 3-items:
1) GBZ FD40- DPFR maintenance Kit
2) EGR MAINTENANCE KIT (with Intake Elbow, no electronic, 1-Block off plate & 2-plugs)
3) FLO-PRO STRAIGHT PIPE
Question: Of the 3-items above, what should I install first?
Answer: It does not matter what order, you must do all three.
Question: Before plugging-in the FD40 into the OBD2, should the truck’s engine be started & running? or in the “Off” position or just pre-ignition [(turn-on only without starting the engine) the whole time of the operation process.]
Answer: Yes, key on engine off.
Question: When installing the FD40, does it require that I first take away the CATALYTIC and DPF FILTER exhaust? or it can be as there intact BEFORE & AFTER installing/operating the FD40?
Answer: It doesn’t matter the order of operations, but you must do all three.
Question: The last exhaust near the tailpipe looks like the exhaust muffler, right? should it be retain?
Answer: Preferably but it is optional.
Question: Can the FD40 solve the 7-DTC (Diagnostic Trouble Codes) Faults issue even without installing the EGR MAINTENANCE KIT (with Intake Elbow) & the FLO-PRO STRAIGHT PIPE? since the EGR maintenance looks like a lot of installation work and will take longer time to install.
Answer: The FD40 can read and clear present DTC’s.
Question: What can happen if I install the FD40 and the operation process was stop or discontinued such as battery became weak, or operation process became confusing for me and would just wish to temporarily discontinue (for reason of finding the next move)?
Answer: You then do special recovery, then proceed to install or reinstall.
Question: Can any stoppage be done in the middle of operation? or can any discontinuation of operation affect or damage the ECU? or its content program? or damage the FD40?
Answer: You can interrupt unless green light is flashing with red light solid.
Question: If operation is successful, do I leave the FD40 remained to be plugged? or UNPLUG after operation?
Answer: It will ask you to unplug the FD40
Question: I want to make sure that if I start the FD40 programming operation and everything seems easy and simple, but in case I will find it difficult along the way, will the whole process be repeated again from the start?
Answer: If the process is not complete, it can be repeated from the start.
Question: What to do in case operation process is unsuccessful?
Answer: Recovery, Return to stock, Reinstall
Question: Does it have a One year warranty?
