Pulse / Fastback / Toro / Titano · Latin America

Where should diagnosis start?

• Evaluate HV/12 V boundary, battery thermal management and energy flow together.
• Compare common-rail pressure, air path, EGR/DPF/SCR and turbo control under the same load condition.
• Separate CVT, D-CVT and e-CVT technically; fluid, clutch, motor-generator and hydraulic architectures differ.

Exact OEM torque, pressure, capacity, pin or calibration values are not inferred from this normalized identity record; a verified service source is required for the exact vehicle application.

System architecture: what does this record indicate?

• Fuel path is separated into low-side supply → high-pressure pump → rail → injectors; air path into MAF/MAP → turbo control → intake manifold.
• On turbo-petrol architecture, load calculation, boost target/actual, lambda/fuel trim, ignition and knock control are compared in the same event window.
• ICE, 12 V, HV/48 V, DC-DC, motor-generator and thermal management are separate control layers; energy flow is aligned with the fault event.
• CVT belt/chain-pulley architecture is not conflated with e-CVT planetary/motor-generator architecture.

Freeze-frame and live-data package

• Freeze frame: first/last fault time, RPM, load, vehicle speed, system voltage, core temperatures and companion DTCs.
• Live data: rail target/actual, low-side supply where supported, MAF/MAP, boost target/actual, EGR command/feedback.
• Aftertreatment: DPF differential pressure, soot/ash calculations, EGT chain, NOx in/out and SCR/DEF dosing enable.
• Live data: calculated load, MAP/boost target-actual, throttle angle, lambda/O2, STFT/LTFT, ignition advance and knock retard.
• Electrified layer: SOC/SOH where available, cell delta, pack temperatures, HVIL/isolation, contactor permission, DC-DC output and 12 V voltage.
• Driveline: input/output speeds, commanded/actual ratio, clutch/TCC slip, fluid temperature, actuator/solenoid command and adaptations.

Measurement sequence

1. 1) Match vehicle/generation/market/powertrain/driveline identity to the source record; family name alone is not fitment evidence.
2. 2) Preserve freeze frame and companion DTCs before clearing; make the first-fault condition reproducible.
3. 3) Verify power/ground and network communication under load; do not decide from key-on static measurement alone.
4. 4) Compare commanded air/fuel/pressure with an independent physical result; separate sensor bias from real performance loss.
5. 5) Compare electronic command → hydraulic/actuator response → mechanical slip/ratio result at the same temperature and load.
6. 6) After repair, recreate the same load/temperature and verify DTC state, live-data deviation and user symptom together.

Root-cause discrimination matrix

• If rail pressure is low, separate low-side supply from high-pressure generation: when physical low-side supply is healthy but rail cannot follow target, regulation/pump/injector-leakage branches gain weight.
• For low boost, do not jump to turbo replacement: separate MAF/MAP plausibility, charge leak, VGT/wastegate command and exhaust backpressure at the same load point.
• On lean/misfire/boost complaints, align fuel trim, lambda, ignition retard and boost deviation on one time base to separate air leak, fuel-delivery and ignition causes.
• For READY/charging faults, separate 12 V supply from the HV permission chain first; low 12 V can mimic contactor/HVIL/isolation faults.
• For battery performance, use cell delta, temperature spread and voltage deviation under load/charge instead of one SoH percentage alone.
• 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.
