P1701 TRANSMISSION CONTROL MODULE (POWER SUPPLY)
Description
INFOID:0000000004201740
When the power supply to the TCM is cut OFF, for example because the battery is removed, and the self-diag-
nosis memory function stops, malfunction is detected.
NOTE:
Since “P1701 TCM-POWER SUPPLY” will be indicated when replacing TCM, perform diagnosis after erasing
“SELF-DIAG RESULTS”
