what does it mean when my Honda CR-V Fifth Generation (2017-2022) shows a P0700 code

Solution

1. Preparation

• Gather all necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, socket set, drain pan.
• Sub-steps:
  1. Locate the transmission fluid dipstick and remove it to check the fluid level.
  2. If low, use the transmission fluid pump to add the manufacturer-recommended fluid type (Honda ATF DW-1).
  3. If the fluid is dark or burnt, drain the old fluid using a drain pan and replace it with new fluid.
  4. Recheck the level with the dipstick after filling.

3. Inspect Electrical Connections

• Tools Required: Multimeter, wire brush, dielectric grease.
• Sub-steps:
  1. Disconnect the battery to ensure safety.
  2. Remove the TCM connector and inspect for corrosion or damage.
  3. Clean the connectors with a wire brush and apply dielectric grease before reconnecting.

4. Test Transmission Solenoids

• Tools Required: Multimeter.
• Sub-steps:
  1. Disconnect the solenoid connectors.
  2. Measure the resistance across the solenoids according to the specifications in the service manual.
  3. Replace any solenoids that are out of specification.

5. TCM Reprogramming or Replacement

• Tools Required: OBD-II scanner capable of programming.
• Sub-steps:
  1. If all previous checks are normal, and the code persists, consider reprogramming the TCM using the OBD-II scanner.
  2. If reprogramming does not resolve the issue, replace the TCM with a new unit.
  3. Follow the manufacturer’s instructions for installation and programming.
