Chrysler 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 Chrysler shares its electronics with Dodge, RAM and Jeep, and the coverage database behind the UCAN-II Pro treats them as one family: the same module names, the same function lists, the same gateway rule. The parts store code reader sees the PCM and stops there. The tools below are what we use in our own shop in Maryland to reach every module on a Chrysler, bleed the brakes with the ABS pump cycling, run Quicklearn after a transmission service and set the body options the dealer charges for. The database lists the LX 300 line, the RU Pacifica, the RT Town and Country and Voyager, the UF 200, the JS Sebring and 200, the PT Cruiser and the ZH Crossfire. Pick by what you need to do, then check the one adapter rule by model year.

Which Scanner Do I Need For A Chrysler?

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 the ABS, airbag, transmission or body modules, and it cannot bleed brakes or run Quicklearn. 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 Security Gateway adapter in the box. Reads and clears every control unit, runs active tests and the Chrysler service functions: brake bleeding, Quicklearn, throttle learn, tire size, body and lighting options, occupant classification verification. The tool to own if you keep a Chrysler 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 brake bleed, Quicklearn or airbag code you need done once.

What The UCAN-II Pro Does On A Chrysler

• ✓ Reads and clears codes in every control unit of the FCA module set: ABS, BCM body controller, ORC airbag, OCM occupant classification, EPB parking brake, EPS steering, ESM electronic shifter, FFCM forward facing camera, ACC adaptive cruise, HVAC, ICS center stack, IPC cluster, door and seat modules and more. A 2022 vehicle in this database lists 37 to 38 of them.
• ✓ Bleed brakes 2WD, 4WD and ABS only from the ABS module, cycling the hydraulic unit while you bleed after a caliper, line or hydraulic control unit job
• ✓ Quicklearn for the RFE transmissions and Quicklearn NOT RFE for the rest, Clear variable line pressure (VLP) counters and the Torque converter clutch (TCC) break in after a fluid service, solenoid pack or rebuild
• ✓ Learn electronic throttle control (ETC) after a throttle body, Reset memory, Check PCM VIN and Check PCM odometer, PCM replaced, and the emissions rolls test mode on the FCM and TIPM for state inspection dynos
• ✓ Program tire size after a wheel or tire change, so the speedometer, ABS and transmission read the right rolling radius
• ✓ Body and lighting options: Activate DRL, Headlamps on with wipers, Illuminated entry time, Auto door lock and unlock, Sound horn on lock, Flash hazard lamps on lock, Deactivate seatbelt minder chime, Trailer tow relay outputs
• ✓ Occupant classification module (OCM) system verification test after a passenger seat or sensor repair, plus the memory seat routines: Easy entry/exit feature, Tilt mirrors in reverse feature, Drive all motors
• ✓ Active tests on more than 30 modules, ECU configure information on 30 more, event data on the PCM, TCM, BCM, ACC and IPC, and mis fire data from the PCM
• ✓ 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 Chrysler

On the tablet you pick the control unit, then the function category, then the routine. These are the routines the coverage database lists for the Chrysler, Dodge, RAM and Jeep family, grouped by the job you are doing, under the category the database calls Special Func. 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 Chrysler

Two 2022 vehicles pulled from the shared FCA 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, configuration data and special functions.

Both samples are Jeeps because Chrysler, Dodge, RAM and Jeep sit in one database with one module naming scheme; the 2022 RU Pacifica is in the same list, and the older LX 300, RT minivans, JS sedans, PT Cruiser and Crossfire each carry their own module set under the same names.

Symptom, Then The Routine That Fixes It

• Spongy pedal after a caliper, line or ABS hydraulic unit replacement: Bleed brakes ABS only, 2WD or 4WD in the ABS module, which cycles the valves while you bleed.
• Harsh or hunting shifts after a transmission fluid service, solenoid pack or rebuild: Quicklearn (RFE) or Quicklearn: NOT_RFE in the TCM, then Torque converter clutch (TCC) break in on a fresh converter.
• High idle or a throttle code after a new throttle body or a cleaning: Learn electronic throttle control (ETC) in the PCM.
• Speedometer and shift points off after a tire or wheel size change: Program tire size.
• Airbag light after a passenger seat, seat track or occupant sensor repair: Occupant classification module (OCM) system verification test.
• Tire pressure light after new sensors: program the U360 sensor to the old ID from the tablet, or trigger and relearn through the WCM/TPMS or TPM module.

Frequently Asked Questions

I have a 2020 Pacifica. What do I need?

The UCAN-II Pro with the FCA 12+8 adapter that comes in its box. The 2018 and newer Pacifica has the Security Gateway Module, and without the adapter a scan tool reads codes and little else. Plug the adapter in behind the gateway and every module answers.

Can it bleed the ABS on my Town and Country after a brake line?

Yes. Bleed brakes ABS only, 2WD and 4WD sit in the ABS module's Special Func menu, and the routine cycles the hydraulic unit while you work the bleeders. The ABS bleeding guide walks through it.

My 300 shifts hard after a fluid change. Will it run Quicklearn?

Yes. Quicklearn (RFE) covers the RFE family and Quicklearn: NOT_RFE covers the others, both in the TCM. Clear variable line pressure (VLP) counters and the TCC break in are in the same menu for a rebuilt unit or a new converter.

Does it program keys or flash modules?

No. Key programming and module flashing need the FCA server through wiTECH. The UCAN-II Pro does diagnosis, live data, active tests, body configuration and the service functions 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 Chrysler add the adapter to the order and keep it. Most Chrysler renters want a brake bleed, a Quicklearn or an airbag light cleared.

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

Use the coverage checker by year, platform 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.
