DIAGNOSIS-AUTOMATIC TRANSMISSION 62-467

Check if the result is normal?
YES> To step 3.
NO> If connector TCU P01 Pin 14 has no battery voltage, repair the open circuit between
fuse F10 (10 A) and connector TCU P01 Pin 14.
If connector TCU P01 Pin 9 has no battery voltage, repair the open circuit between
fuse F19 (5 A) and connector TCU P01 Pin 9. 62
