Intermittent fault

Check the power supply cable between control module terminal #A57 (#A57) and transmission output sensor terminal #A4. Check for an intermittent open-circuit according to Open-circuit, intermittent faults . Check for an intermittent short-circuit to ground according to Short-circuit to ground, intermittent faults .

Check the signal cable between control module terminal #A39 (#A39) and transmission output speed sensor terminal #A3. Check for an intermittent open-circuit according to Open-circuit, intermittent faults . Check for an intermittent short-circuit to ground according to Short-circuit to ground, intermittent faults .

Remedy as necessary.
