Maserati 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.

A modern Maserati is built on FCA electronics: a 2019 Levante lists 41 control units in the coverage database and a 2022 Quattroporte 42, from three engine control module variants and the ZF transmission control to the air suspension, the adaptive lighting, the door modules and the amplifiers, all behind the Security Gateway on the 2018 and newer cars. The tools below are what we use in our own shop in Maryland to reach every module on a Ghibli, Quattroporte, Levante or GranTurismo, run the resets and calibrations after an oil change, a brake job or a suspension repair, and command the components the dealer charges an hour of labor to test. The coverage database runs from the 3200 GT, the Coupe, Spyder and GranSport and the M139 Quattroporte of 2004 to the 2022 Ghibli, Quattroporte and Levante. Pick by what you need to do.

Which Scanner Do I Need For A Maserati?

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, airbag, transmission, air suspension or body modules, and it cannot run a reset or a calibration. 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, with the FCA 12+8 adapter in the box. Reads and clears every control unit, runs the active tests and the Maserati special functions: oil reset, adaption resets, sensor calibrations, parking brake mounting position, air suspension height calibration, DPF and SCR routines, clutch calibration, door and actuator calibrations. The tool to own if you keep a Maserati 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 oil reset, parking brake job or airbag code you need done once. On a 2018 or newer car add the 12+8 adapter to the order; the rental kit does not include it.

What The UCAN-II Pro Does On A Maserati

• ✓ Reads and clears codes in every control unit: 41 modules on a 2019 Levante and 42 on a 2022 Quattroporte, from the ECM V6, V6D and V8 engine control modules and the TCM to the ESC, ORC airbag, IPC cluster, TPM, the four door modules, AFLS and AFLS LED lighting, the amplifiers, ANC, ASCM air suspension, AWD and BCM (the table below lists them)
• ✓ Engine: Manual Oil reset, Reset of Oil life time values in EEPROM, Reset Zero Fuel Calibration (ZFC) values, Reset of Lambda values, Canister purge valve, Diagnosis wastegate and dump valve, Erase Env RAM, Pressure preparation test, Spray test, Backflow pump test
• ✓ Diesel: Diesel Particulate Filter (DPF), Set EEPROM values for particulate filter corgn exchange of ECU, Exhaust Gas Recirculation (EGR) offset reset and activation of the learning, Emptying of Selective Catalyst Reduction (SCR) system, Leak test of Selective Catalyst Reduction (SCR) system
• ✓ Transmission and drivetrain: Reset adaption values, Calibrate clutch, Set clutch torque, Power down calibration, AWD reset for oil substitution
• ✓ Brakes and chassis: Longitudinal and lateral sensor calibration, Satellite sensor general information, Braking static deactivation and activation, Run to Mounting position on the electronic parking brake, Height sensor calibration and Level motor reference on the air suspension, CoolDown Test
• ✓ Body and comfort: Door system calibration, Oem Factory calibration, LIN ECU reset, Self-learning motors end of travel, Self-learning electric valve presence, Actuator calibration, Positioning routine, ITM self test, RTT and RRT test modes, Ultrasonic motion detection test, Clear alarm trigger monitors
• ✓ Cluster and audio: Instrument Panel Cluster (IPC) self test, Write service information, Start amplifier diagnostic, Output short test, Test signal
• ✓ Active tests on the engine control modules, ESC, cluster, TPM, door modules, ADCM active damping, AFLS, amplifier, ANC, BCM, comfort seats and wheel, electronic shifter and heated rear seats
• ✓ Live data with graphing and recording, plus TPMS: triggers the sensors and programs the U360 replacement sensor from the tablet

Service Functions By Job On A Maserati

On the tablet you pick the control unit, then the function category, then the routine. The Maserati database carries two categories, Special Functions (the service routines) and Active Test (bidirectional tests). These are the routines the coverage database lists for Maserati, 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 A Maserati

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.

Symptom, Then The Routine That Fixes It

• Service light still on after an oil change: Manual Oil reset, or Reset of Oil life time values in EEPROM, in the engine control module.
• Rear pads on a car with the electronic parking brake: Run to Mounting position before the job and Braking static activation after it, in the EPB module.
• Stability warning after an alignment, a rack or a sensor replacement: Longitudinal and lateral sensor calibration in the ESC module.
• Levante sitting low or uneven after a strut, compressor or height sensor job: Height sensor calibration and Level motor reference in the ASCM air suspension module.
• Harsh engagement after a clutch or transmission repair on a dual clutch car: Calibrate clutch and Set clutch torque, then Reset adaption values in the TCM.
• Window or door lock faults after a door module or regulator replacement: Door system calibration in the door module.

Frequently Asked Questions

Do I need the 12+8 adapter for my 2019 Levante or Ghibli?

Yes. The 2018 and newer Ghibli, Quattroporte and Levante carry the FCA Security Gateway, and without the adapter the scanner sees engine codes and little else. The FCA 12+8 adapter comes in the UCAN-II Pro box; plug it in behind the gateway under the dash and every module answers.

Will it reset the oil service light on my Quattroporte?

Yes. Manual Oil reset and Reset of Oil life time values in EEPROM are in the engine control module's special functions on the cars that list them. Check your year in the coverage checker first.

Can it put the parking brake in service mode for rear pads on a Ghibli?

Yes. Run to Mounting position, Braking static deactivation and Braking static activation are in the EPB special functions. The parking brake guide walks through the order.

Does it program keys or flash modules on a Maserati?

No. Key and module programming need the manufacturer server. The UCAN-II Pro does diagnosis, live data, active tests and the resets and calibrations 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. The rental kit does not include the 12+8 adapter, so on a 2018 or newer car add the adapter to the order and keep it. Most Maserati renters want an oil reset, a parking brake job or an airbag light cleared.

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

Use the coverage checker by model 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.
