Research focus: verify platform/generation, powertrain/energy/driveline and market-specific application identity against manufacturer/source records before applying parts, service procedures or chronic-fault claims.

System map

• CVT, D-CVT, IVT and e-CVT are not the same mechanism; identify belt/chain, planetary, motor-generator and hydraulic architecture.
• In ADAS diagnosis, glass/bracket, ride height, tires, alignment and calibration prerequisites matter as much as the sensor.
• For network faults, evaluate source ECU, gateway path, power/ground and wake/sleep behaviour together.

Measurement and verification sequence

1. Check alignment, ride height, yaw/steering-angle references and sensor mounting geometry alongside DTCs.
2. Measure CAN-H/CAN-L bias and termination under the fault condition, not only key-on; capture message timing with source address.

Misdiagnosis traps

• Wrong fluid/procedure or transmission-family identity distorts fault and fitment diagnosis.

Variant-specific system split

• CVT belt/chain-pulley architecture is not conflated with e-CVT planetary/motor-generator architecture.

Freeze frame / live data

• Freeze frame: first/last fault time, RPM, load, vehicle speed, system voltage, core temperatures and companion DTCs.
• Driveline: input/output speeds, commanded/actual ratio, clutch/TCC slip, fluid temperature, actuator/solenoid command and adaptations.

Root-cause split

• For CVT ratio faults, identify the architecture first; e-CVT motor-generator power split and belt/chain CVT hydraulic-pulley faults do not share the same diagnostic tree.

What should be verified first?

Model name alone is insufficient. Do not generalize parts fitment, chronic issues or service procedures until production period, market, platform/generation, powertrain, transmission and controller identity are matched.
