Intermittent fault
Check the control module and transmission connectors. Check for contact resistance and oxidation.
Check the cable between control module terminal #37 (#A37) and transmission connector (control module side) terminal #11. Check for an intermittent short-circuit to ground. Check for a short-circuit to supply voltage.
Check the cable between control module terminal #55 (#A55) and transmission connector (control module side) terminal #12. Check for an intermittent short-circuit to ground. Check for a short-circuit to supply voltage.
Remedy as necessary.
