symptoms

Signals worth recording

Use the linked symptoms and codes as observation and testing prompts, not as proof of the failed part. Preserve freeze-frame data and the operating conditions before clearing codes.

dtcs

  • U0100 — Communication with the engine or powertrain controller was lost

symptoms

  • Battery warning light — The charging-system warning lamp is on.
  • No crank — The starter does not turn the engine when start is requested.

diagnosis

A safer diagnostic sequence

Verify VIN and build applicability, reproduce and document the symptom safely, scan all relevant modules, complete the least-invasive confirming tests, then compare the findings with the current manufacturer procedure.

actions

  • Test battery and charging system — Measure battery condition, cranking voltage, charging voltage, and excessive voltage drop.

costs

Repair-cost scope

No dollar estimate is inferred from a complaint, code, or component label. A credible quote identifies the confirmed repair scope, parts grade, labor operations, region, taxes, fees, and any programming or calibration.
