ERICSDIYGARAGE put the iCarsoft CR Max P into daily workshop use for about three weeks, then connected it to a Jaguar XJR with a rough idle and a check-engine light. The tablet identified the car, scanned its control modules, opened powertrain live data and showed which fault remained after a Quick Erase.
Watch the CR Max P Jaguar XJR review
The 14-minute, 40-second video covers the supplied kit, the CR Max P interface and a diagnostic session on the Jaguar. The vehicle work begins near 3:20, with VIN identification at about 5:30 and full-system results from about 6:40.
CR Max P hardware in a working mechanic's hands
The case contains the 10-inch tablet, wireless VCI, USB-C charging cable, charger, wired network equipment, instructions and a cleaning cloth. The presenter also notes that a videoscope and battery tester are available separately. His daily-use comments focus on the tablet rather than the optional accessories.
The tablet has a rear stand and a storage slot for the VCI. The reviewer finds the plastic stand sturdy in use. He also points out that the VCI has an integrated light, which helps locate an OBD-II socket under the dashboard.
Current store specifications versus the figures spoken in the video
The reviewer says the unit has 64 GB of "RAM" and refers to 40 reset services. The current U.S. product listing identifies the 64 GB figure as storage, not system memory, and lists 50 service functions. Listings and software change, so current buyers should use the live product page rather than an older spoken count.

The video calls it a 2005 XJR, but AutoVIN reports 2004
Before connecting the scanner, the presenter identifies the car as a 2005 Jaguar XJR with 97,000 miles. After the VIN read, the CR Max P screen reports a 2004 Jaguar with a 4.2-liter engine. The video does not reconcile the difference.
Model-year differences can come from registration conventions, build dates, prior vehicle information or a simple spoken mistake. This article does not choose one result over the other. A technician should record the VIN, confirm the certification label and verify the exact configuration before ordering parts or running a year-specific procedure.
AutoVIN works after the make is selected
The main diagnostics screen presents vehicle makes rather than a separate AutoVIN button. The reviewer selects Jaguar, waits for the tablet to connect to the VCI and chooses VIN identification. The VIN appears quickly and the tool identifies the engine and model year.
He would prefer one AutoVIN control on the main menu. That is an interface criticism, not an identification failure. In this session, the added step still leads to a successful VIN read.
The reviewer then starts Auto Scan. He explains that he scans customer vehicles before and after work so there is a record of pre-existing faults. The Jaguar returns responses from powertrain, chassis, body and convenience modules. Several rows carry red fault counts while others pass.
The visible powertrain codes need separate diagnostic plans
The powertrain screen confirms three codes:
- P0171: System too lean, bank 1
- P0174: System too lean, bank 2
- P0702: Transmission control system electrical
The presenter also discusses P1000, explaining that the vehicle has not completed its self-test sequence. On Ford and Jaguar applications, P1000 commonly records that OBD readiness monitoring is incomplete. It may appear after codes are cleared, the battery is disconnected or the required drive cycles have not finished. It does not identify the failed part behind the rough running.
P0171 and P0174 do not condemn the mass airflow sensor
Because both banks report lean, the presenter suggests that the mass airflow sensor may be involved. That is a diagnostic idea, not a confirmed failure. The video does not show fuel trims, smoke testing, fuel-pressure measurement, intake inspection or comparison of measured airflow with expected engine load.
A technician would normally preserve freeze-frame data, inspect for unmetered air and check fuel delivery before replacing the mass airflow sensor. Engine condition, exhaust leaks ahead of oxygen sensors and biased sensor data can also affect mixture diagnosis. The next test should follow the data rather than the first plausible part.
P0702 deserves its own electrical diagnosis
P0702 is shown with the description "Transmission control system electrical." The video does not open the transmission module to identify supporting codes or test power, grounds and network signals. Clearing it may remove the warning temporarily, but it does not establish whether the original condition came from low voltage, wiring, a module or another input.
Searchable live data is the strongest workshop feature shown
The CR Max P opens the Jaguar PCM data list and lets the user search for a parameter instead of scrolling through every item. The reviewer demonstrates that search behavior and changes how selected values appear.
Values can be viewed as text, graphs or dial-style gauges. The interface also offers unit selection, recording, screenshots and report functions. A saved recording can help when a symptom appears only under load, but this video does not include a road-test capture or interpret fuel-trim graphs.
The screen size earns specific praise. The reviewer had grown accustomed to smaller tablets, then found the 10-inch display faster to navigate during everyday work. His main display complaints concern brightness and the red type used for fault rows, which the camera also struggles to capture.
Quick Erase cleans the list, then C1742 remains current
The reviewer uses Quick Erase because the initial scan contains many entries. The rescan completes quickly and most of the visible module rows change to Pass. One current code remains when he opens the affected system.
The tablet screen shows C1742, state Current, with the description Rear sounder - circuit failure. The presenter speculates about a rear sensor or parking aid issue. No circuit test follows, and the footage does not confirm a failed sensor. The scanner wording points to the rear sounder circuit, but the sounder, power supply, ground, connector, wiring and control command still need to be checked.
This is the useful reason to rescan after a clear. Stored or low-voltage history can drop out while a current electrical fault returns immediately. The remaining entry becomes the next test, not an automatic parts order.
Service coverage varies, and no active test is demonstrated
The CR Max P is sold as a bidirectional full-system scanner, but this particular video does not command a Jaguar actuator. The reviewer first looks for special functions inside the engine and transmission modules and does not find the procedures he wants. He then opens the Services menu and tries the electronic throttle control procedure for Jaguar.
The unsuccessful procedure is valuable coverage evidence. A scanner may list a service category at the top level while a specific year, engine or control module does not provide that function. The presenter attributes the result to the age of the Jaguar, but the footage does not establish the technical reason. Confirm coverage for the exact VIN and software version before buying a tool for one required procedure.
The presenter mentions using the tool for coding work on other vehicles, including a BMW, but those sessions are not shown here. They should not be counted as demonstrated Jaguar capabilities.
Who should consider the CR Max P?
This test supports the CR Max P as a practical multi-make workshop tablet. The Jaguar scan reaches many systems, reads the VIN after the make is selected, organizes full-system results and offers useful ways to search, record and present live data. The post-clear scan also separates a current C1742 circuit fault from a much larger initial list.
The video shows limits without hiding them. AutoVIN needs an extra navigation step, screen brightness and red fault text bother the reviewer, and the electronic throttle control service procedure is unsupported on this car. No bidirectional actuator command appears, so this review cannot verify Jaguar XJR active-test coverage.
Bottom line: CR Max P makes sense for technicians and experienced owners who need broad module access, a large display and lifetime updates at the current mid-range price. Buyers seeking one Jaguar-specific reset or actuation should verify that exact function before purchase.

View iCarsoft CR Max PFrequently asked questions
Which Jaguar XJR was tested with the CR Max P?
The presenter calls the car a 2005 Jaguar XJR with 97,000 miles. The CR Max P VIN result identifies it as a 2004 Jaguar with a 4.2-liter engine. The video does not resolve the model-year difference, so both observations should remain in the record.
Which fault codes did the CR Max P show on the Jaguar?
The visible diagnostic screen shows P0171 for system too lean on bank 1, P0174 for system too lean on bank 2 and P0702 for a transmission control system electrical fault. The presenter also discusses P1000, which indicates that the readiness or self-test sequence is incomplete.
Do P0171 and P0174 prove that the mass airflow sensor is bad?
No. The presenter suggests possible mass airflow sensor involvement, but the video does not test or condemn that sensor. Lean codes on both banks require diagnosis of the measured airflow, unmetered air, fuel delivery and related data before parts are replaced.
Which fault remained after Quick Erase?
The post-clear screen shows current code C1742 with the description Rear sounder - circuit failure. The video does not trace the circuit or confirm a failed sensor, sounder, connector or wire, so the cause remains unconfirmed.
Did the Jaguar test demonstrate a bidirectional actuator command?
No. The video shows scanning, code reading, live data, graph and dial views, report features, Quick Erase and a service-function attempt. The electronic throttle control procedure reports that it is not supported on this vehicle, and no actuator command is demonstrated.
How does AutoVIN work on the CR Max P in this test?
AutoVIN is not shown as a separate button on the main menu. The presenter selects Jaguar, connects to the wireless VCI and then chooses VIN identification. The tablet reads the VIN and identifies a 2004 Jaguar with a 4.2-liter engine.
What are the current CR Max P price and service-function count?
The iCarsoft US listing showed $599.99, 64 GB storage, 50 service functions and lifetime free updates on July 20, 2026. The storefront listed the product as backordered. Function availability varies by vehicle, model year and control module.
