This worked perfectly on my 05 Isuzu npr with the 4HK1 Diesel engine. It led me down the right path immediately. That’s where I found a broken wire at the boost sensor. I probably never would have found it on my own.
- Engine: Today’s engines are complex systems, using feedback loops from intake air temperature and flow, manifold absolute pressure, engine coolant temperature, crankshaft and camshaft position, oil pressure, fuel rail pressure, fuel tank pressure, vehicle speed and many other inputs to determine correct air/fuel ratios, camshaft timing, ignition timing and other, critical, operational parameters. FCAR 506 OBD2 Scanner speeds diagnosis by providing the user access to critical OBD II standard data as well as extended, manufacturer specific, data on Live Data, Freeze Frame, Erase Fault codes and ECU Information, at the touch of a button.
- Transmission: Today’s automatic transmissions (A/T), like our engines have evolved into a complex system of mechanical, electrical and control systems interaction. Today’s transmissions provide a wealth of information about the success of up and downshifts, solenoid action (too harsh, too soft), clutch engagement, fluid temperature, fluid level, pressure, and other, critical, operational and diagnostic information. The FCAR 506 TRUCK Scanner provides the user a detailed view into this critical components operation and function, allowing fast, accurate and complete diagnosis of existing, or potential issues.
- ABS: Like other systems, braking systems have evolved and become more complex, with multiple sensors and actuators operating together to make braking more smooth, consistent and safe for everyone. The FCAR 506 obd2 scanner allows the user to monitor and diagnose critical ABS systems to ensure that repairs to this critical system are effective, and complete.
- SRS: A well-functioning, always ready, Supplemental Restraint System (SRS) is absolutely critical for occupant and driver safety. Even minor issues might impact the operation, and performance, of the SRS system. The FCAR 506 truck scanner quickly, and efficiently, allows the user to retrieve, read and interpret SRS system issues and monitor SRS system functionality to rapidly diagnose, and repair, the cause of the issue.
- Works on most 1992 and newer vehicles (OBDII &CAN) and Trucks.
- Transmission/ABS coverage and more for diagnostic trouble codes!
- Read and clear diagnostic trouble codes.
- Graphs data
- Provides on screen DTC definitions for heavy-duty standard codes.
- SD memory card for extra storage
- Internet update capable.
- Question: Does this work for peterbilt?
Answer: works on my 2015 579 with cummings eng. will not do a forced regen, you will need the OTR reset tool for cummings – WORKS ON PETERBILT / KENWORTH / FREIGHTLINER / INTERNATIONAL with CM2250, CM2350, ISX, CM871 ENGINES - Question: Can this fcar f506 do forced regen on a 2013 isuzu nqr? can this clear any and all codes including codes to remove the system from “derate”?
Answer: Hi, thanks for your inquiry. If the issue to cause the engine derate has been fixed, the F506 scanner can clear the fault codes for 2013 isuzu nqr. Otherwise, you need to find out the cause and fix this problem first. As for regen, I am sorry to tell you that this scanner is unable to do forced regen on any trucks.
