Checking the wiring

Check the wiring between the transmission connector (control module side):

• terminal #F (#A6) and control module terminal #A46 (#A46) "A"
• terminal #G (#A7) and control module terminal #A64 (#B4) "B"
• terminal #H (#A8) and control module terminal #A45 (#A45) "C"
• terminal #J (#A9) and control module terminal #A63 (#B3) "PA".

check for an open-circuit. Check for a short-circuit to ground. Check for a short-circuit to supply voltage.
