Transmission Control System Malfunction

Understand P0700, common causes, and the right TOPDON scanner to diagnose it.

General transmission fault — TCM detected a problem and requested MIL. Read sub-codes with a full-system scanner for specifics.

Vanliga symptom

  • Harsh or delayed shifts
  • Slipping
  • Transmission warning light
  • Limp mode

Typiska orsaker

  • Low transmission fluid
  • Failed shift solenoid
  • Internal wear
  • TCM communication fault

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
