Infiniti Diagnostic Scanners and Adapters

Written by the YOUCANIC technicians in Towson, Maryland, from the UCAN-II Pro coverage database and our own shop work. Updated October 24, 2026.

An Infiniti runs on Nissan electronics: the same ENGINE, ABS, BCM, air bag and transmission modules, the same work support routines, and on the newer cars the electric parking brake, the 4WAS steering and the CVT learning the dealer charges an hour of labor for. The parts store code reader sees the engine and nothing else. The tools below are what we use in our own shop in Maryland to reach every module on an Infiniti, run the CVT and steering angle learns, put the parking brake in pad replacement mode and clear the light for good. The coverage database behind the UCAN-II Pro lists the whole lineup, from the G20, I30, I35, Q45 and QX4 through the G35, G37, M35, M45, FX35, FX50, EX35, JX35 and QX56 to the Q50, Q60, Q70, QX30, QX50, QX55, QX60, QX70 and QX80. Pick by what you need to do, then read the adapter note.

Which Scanner Do I Need For An Infiniti?

CHECK ENGINE LIGHT ONLY

UCAN-GO

Reads and clears engine codes from your phone and gives you a live gauge dashboard. It does not see ABS, air bag, transmission or body modules, and it cannot run a learn or a work support routine. Right if the only light you care about is the engine one.

EVERY MODULE, EVERY SERVICE FUNCTION

UCAN-II Pro, new or open box

Full system, bidirectional, lifetime free updates. Reads and clears every control unit, runs the active tests and the Infiniti work support routines: idle air volume learn, throttle closed position learn, steering angle sensor adjustment, decel G sensor calibration, CVT fluid deterioration reset, clutch point learning, parking brake pad replacement mode, TPMS ID registration. The tool to own if you keep an Infiniti running.

ONE JOB THIS MONTH

Rent the UCAN-II Pro for a week

Same scanner, shipped both ways free, with a refundable deposit that comes back when the scanner does. For the one idle relearn, steering angle adjustment or air bag code you need done once.

What The UCAN-II Pro Does On An Infiniti

• ✓ Reads and clears codes in every control unit: ENGINE, TRANSMISSION, ABS, AIR BAG, BCM, METER/M&A, IPDM E/R, HVAC, MULTI AV, EPS, AIR PRESSURE MONITOR, INTELLIGENT KEY, ICC/ADAS, LANE CAMERA, SONAR, AVM, ADAPTIVE LIGHT, ALL MODE AWD/4WD, 4WAS steering and the EHS/PKB parking brake, as the database names them
• ✓ Engine work support: Idle Air Vol Learn, Throttle Closed Position Learn, Target Idle RPM Adj, Fuel Pressure Release, A/F Initial Learning and VIN Registration, plus the DTC work support menu that runs the sensor and EVAP checks behind a stored code
• ✓ CVT and automatic transmission learning: fluid deterioration reset, erase learning value, clutch point learning, G sensor calibration and the selection range sensor teach in
• ✓ Chassis: steering angle sensor adjustment, decel and side G sensor calibration, and the valve check, valve flushing and manual exhaust routines on the ABS unit
• ✓ Start and finish brake pad replacement on the EHS/PKB electric parking brake, with actuator zero point learning
• ✓ Active tests on the engine, ABS, BCM, IPDM and lighting modules: injectors, ignition timing, power balance, cooling fan, fuel pump relay, ABS motor and solenoids, door lock, rear defogger, chimes and lamps
• ✓ Body customizing on the BCM: lamp timers, battery saver, auto lock and unlock, wipers, daytime running lights, answer back and the security alarm
• ✓ TPMS on the AIR PRESSURE MONITOR module: ID registration, register or switch ID, TPMS on and off, plus the U360 replacement sensor programmed from the tablet. Live data with graphing and recording on every module.

Service Functions By Job On An Infiniti

On the tablet you pick the control unit, then the function category, then the routine. These are the routines the coverage database lists for Infiniti, grouped by the job you are doing. Names are as they appear on the tablet. Coverage varies by model and year, so check yours before you order.

What The Scanner Sees On An Infiniti

Two vehicles pulled from the coverage database, with the control units the UCAN-II Pro lists on each. Every unit gets fault codes, live data and, where the database shows it, active tests and special functions.

The Infiniti database lists the full Nissan family module set against each model; on the car, the tablet shows the units your model is actually fitted with.

Symptom, Then The Routine That Fixes It

• Idle hunting or a stall after a throttle body cleaning or a battery disconnect: Throttle Closed Position Learn, then Idle Air Vol Learn on the ENGINE module.
• VDC or slip light after an alignment, rack or steering column work: St Angle Sensor Adjustment and Decel G Sen Calibration on the ABS module.
• Spongy pedal after a caliper, line or actuator job: Valve Flushing and Manual Exhaust on the ABS module to move the trapped air.
• Rear pads on a car with the electric parking brake: Start Brake Pad Replacement on EHS/PKB, then Finish Brake Pad Replacement when the pads are in.
• Harsh or lazy shifts after a CVT fluid service or a valve body: Conform CVTF Deteriortn to reset the fluid counter and Erase Learning Value on the TRANSMISSION module.
• TPMS light after new sensors or a tire rotation: Id Regist or Register/Switch ID on the AIR PRESSURE MONITOR module, with the U360 programmed from the tablet.

Frequently Asked Questions

Does my Infiniti need an adapter?

No. Every Infiniti in the coverage database uses the standard 16 pin port under the dash, and the UCAN-II Pro plugs straight in. Nothing else to buy.

Will it do the idle air volume learn on my G35 after I cleaned the throttle body?

Yes. Throttle Closed Position Learn and Idle Air Vol Learn are both in the ENGINE work support list, and that is the order to run them. The database also lists Target Idle RPM Adj and Self Learning Cont for the same module.

Can it reset the CVT fluid deterioration counter on my QX60 or JX35?

Yes. Conform CVTF Deteriortn is listed on the TRANSMISSION module, along with Erase Learning Value and the clutch point learning routines for the newer units. The transmission adaptation guide explains when to run each.

Does it program keys or intelligent keys?

No. Key programming needs the Nissan server through CONSULT. The UCAN-II Pro does diagnosis, live data, active tests, calibrations and the work support routines listed above.

Can I rent it for one job?

Yes. The rental is a one week rental plus a refundable deposit that comes back when the scanner does, shipped free both ways. Most Infiniti renters want an idle relearn, a steering angle adjustment after an alignment or an air bag light cleared.

How do I know my exact car and function are covered?

Use the coverage checker by model, chassis code and module, or call 1-888-959-4265, Monday to Friday 9 AM to 4 PM Eastern, and a technician will tell you plainly. If it does not do what you need, we will say so. Every scanner also comes with 31 day returns, no questions asked.
