Transmission Control System Range/Performance

Understand P0701, common causes, and the right TOPDON scanner to diagnose it.

General transmission control system performance fault — TCM detected abnormal operation.

Vanliga symptom

  • Harsh or delayed shifts
  • Trans warning light
  • Limp mode

Typiska orsaker

  • Low ATF level
  • Dirty or burnt fluid
  • Internal wear
  • TCM software or sensor issue

Vilken scanner behöver du?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Använd live-data och freeze frame innan du byter delar. ABS-, SRS- och U-koder kräver oftast en fullsystems-scanner.

Diagnostiktips

  • Spara freeze frame när koden först sätts
  • Rensa koden först efter att orsaken är åtgärdad
  • Kontrollera relaterade väntande koder
  • Verifiera batterispänning över 12,4 V innan du misstänker sensorer
