TCM Reprogramming
IMPORTANT: Repairs performed for this bulletin require CONSULT-III plus (C-III plus)
Diagnostic result reporting function-Setting be turned ON and Diagnosis (All Systems) be
performed. If not done, it may result in a repair being non-warrantable.
IMPORTANT: Before starting, make sure:
 ASIST on the CONSULT PC has been synchronized (updated) to the current date.
 All C-III plus software updates (if any) have been installed.
 The CONSULT PC is connected to the Internet (Wi-Fi or cable).
HINT:


Most instructions for reprogramming with C-III plus are displayed on the CONSULT
PC screen.



If you are not familiar with the reprogramming procedure, click here. This will link
you to the "CONSULT- III plus (C-III plus) Reprogramming" general procedure.

208. Connect the plus Vehicle Interface (plus VI) to the vehicle.
Make sure the plus VI is securly connected. If the plus VI connection is
loose during reprogramming, the process will be interrupted and the TCM may be
damaged.
209. Connect the AC Adapter to the CONSULT PC.
Be sure to connect the AC Adapter. If the CONSULT PC battery voltage
drops during reprogramming, the process will be interrupted and the TCM may be
damaged.
210. Connect a battery maintainer or smart charger, set to reflash mode or a similar setting,
to the vehicle battery.
Be sure the battery maintainer or smart charger is connected securely
to the battery. Make sure the battery voltage stays between 12.0V and 15.5V
during reprogramming. If the battery voltage goes out of this range during
reprogramming, the TCM may be damaged.
211. Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.) within range
of the CONSULT PC and the VI.
Make sure to turn OFF all external Bluetooth® devices. If Bluetooth®
signal waves are within range of the CONSULT PC and the VI during
reprogramming, reprogramming may be interrupted and the TCM may be
damaged.
212. Turn the ignition ON with the engine OFF.


The engine must not start or run during the reprogramming procedure.

213. Turn OFF all vehicle electrical loads such as exterior lights, interior lights, HVAC,
blower, rear defogger, audio, NAVI, seat heater, steering wheel heater, etc.
Make sure to turn OFF all vehicle electrical loads. Make sure the
battery voltage stays between 12.0V and 15.5V during reprogramming. If the
battery voltage goes out of this range during reprogramming, the TCM may be
damaged.
