System map

• CVT, D-CVT, IVT and e-CVT are not the same mechanism; identify belt/chain, planetary, motor-generator and hydraulic architecture.

Measurement and verification sequence

1. Capture first/last fault time, engine temperature, load, rpm, speed and system voltage.
2. Verify power/ground and network communication under load; compare commanded value with actual response.
3. Recreate the operating condition after repair and prove the symptom does not return.

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.
