How do I fix code iso 9141 ona 2014 Infiniti QX80
iso 9141 that is no OBD2 DTC error that is the protocol name, (usa spec.)you scan the PCM at the 16pin DLC OBD2 port using a scan tool.OBD2 is USA invention that other countries copied, EOBD and JOBD tool.no country told at all. so no real easy answers ever. lacking that.all fuses goodscan DLC port. to see DTC errors.there are like 1000;'s of scan tools sold world wide, none told (yes some brands of tools, yes, (I like this) Laumch(tm) example.boots and shows he port scans. on the screen.from old cars to new. iso-9141 (kline)SAE-j1850 ISO-15765 (modern cars Can_bus 2pins) 2008 and newer cars use this port. only.Your 2014 car uses , can_Bus pins 6 and 14if the cars DLC pin 16 has dead 12vdc on that pin (fuse is blown) commuications will fail and tool is deadusing old 1996-2007 era scan tools on this car is not going to work, .the tool must marked, CAN_BUS READY or fails.
Gear shifter stuck in park and car will not start
The can can't run. Why need to shift...?If you want to shift anyway. Be careful if down or up hill the car will roll.Here if need to shift away:-Put key in ignition, turn to start, but do not start.Now apply brake then shift.Mai Lor
Infiniti Fx 35 2009 Brake lights won't turn off even when car is completely off
NOT TOLD THIS.
DOES CAR DRIVE AND RUN OK DAY OR NIGHT, GEE NOT TOLD.
KEY OFF HEADLAMPS ARE BRIGHT.?
ALL FUSES TEST GOOD.?
SCAN THE CAR (PCM) YET. OOPS IT TELLS YOU WHAT IS WRONG.
MOST MODERN CARS THE BCM RUNS LIGHTS. ALL OF THEM AND MORE
the only easy cure is remove the battery neg lug off battery and wait 1/2hour and put it back hoping the BCM wakes up.
or the brake switch is bad.
scanning finds is , why wait to scan it?
many places do it for free. or buy the tool and uses it.
1997 infiniti j30 won't start
An engine that will crank but not start can be tricky to diagnose. First, we can rule out the battery, starter and circuits in-between due to the cranking condition. The three areas to focus our attention on are compression, spark and fuel. Generally speaking, a compression gauge should show each cylinder at above 100 PSI for an engine to run. Low compression would have to be present across all cylinders (or at least one bank on a v-shaped engine) to generate a no-start condition which would be indicative of a timing belt or other mechanical issue. Next, a spark tester should show ignition spark present while the engine is cranking. With a coil-on-plug (COP) setup it would be inconceivable for all six plugs or coils to fail simultaneously, therefore if spark is not present it would point to a crankshaft position sensor (CKP) or other control-side issue. Lastly, there is the fuel system which is two-fold; fuel supply and fuel delivery. Fuel supply is the fuel pump which takes fuel from the tank and supplies it to the fuel rail at the engine. The fuel pump should prime (turn on for a few seconds) when the key is cycled on. Fuel pressure can be checked at the fuel rail for proper operation or alternatively a flammable aerosol such as starting fluid can be sprayed into the intake while cranking to see if the engine runs. Fuel delivery on the other hand consists of the fuel injectors which must be modulated. Much like the ignition coils it is not likely to have six injectors fail at once, therefore if fuel is not injecting into the intake it would point to a camshaft position sensor (CMP) or other control-side issue.

Where is the fuel pump
The fuel pump is located behind the driver seat on the 2nd row under that seat. You have to cut a piece of the carpet out to get to it. Why I have no idea why Nissan built a vehicle where you have to cut the rug out to get to a part that will need to be replaced one day.
