- This is not an OBD-II self-diagnostic item.
- Diagnostic trouble code "TCM-POWER SUPPLY" with CONSULT-II is detected when TCM does not receive the voltage signal from the battery power supply.
- This is not a malfunction message. (Whenever shutting "OFF" a power supply to the TCM, this message appears on the screen.)
