Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface with the parking brake engaged.
  • Disconnect the battery to prevent electrical shorts.
2. Check Transmission Fluid
  • Tools Required: Dipstick, funnel
  • Remove the transmission dipstick and check the fluid level and condition.
  • If low, add the appropriate type of transmission fluid (Toyota Type T-IV).
  • If the fluid is dark or has a burnt smell, consider a fluid change.
3. Inspect Wiring and Connectors
  • Tools Required: Multimeter, dielectric grease
  • Remove the cover for the transmission control module.
  • Visually inspect all wiring harnesses and connectors for damage.
  • Use a multimeter to check continuity and voltage at the connectors.
  • Clean any corrosion from connectors and apply dielectric grease before reassembly.
4. Test and Replace TCM (if necessary)
  • Tools Required: Multimeter, socket set
  • Test the TCM using a multimeter to ensure it receives the correct voltage and signals.
  • If the TCM is faulty, remove it by unscrewing the mounting bolts and disconnecting the wiring harness.
  • Install the new TCM by connecting the harness and securing it with bolts.
5. Reset Error Codes
  • Tools Required: OBD-II scanner
  • Reconnect the battery and use an OBD-II scanner to clear the P0700 code.
  • Start the vehicle and observe if the check engine light returns.
