VI. CONNECT THE BATTERY CHARGER
Before starting the reprogramming procedure, please make sure you have connected the DCA-8000 battery charger. The usage of a charger during the ECU Software update process is mandatory.
During this reprogramming the headlights will turn on, and the seats and other electrical components will function. To prevent damage to the ECU’s, due to flat battery or voltage drop, ALWAYS connect the specified battery charger.
Unlike other Toyota vehicles, the new Toyota Supra is capable of drawing high amperage (a peak of 70 Amps flows at maximum) during diagnosis and repair. The Toyota Supra is equipped with an AGM type battery, discharges will affect the life span of the battery. AGM batteries must not have a charging voltage that exceeds 14.6 volts.
- Always connect the power supply of the battery charger to an outlet directly. If a power strip or other device is used, and multiple electrical components are connected, the battery charger may detect a power supply error due to insufficient current, and it may not be possible to charge the battery.
- Make sure that the battery charger is off before connecting it.
- Make sure you respect the correct polarity when connecting the battery charger cables like displayed in the illustration below.
- DO NOT disconnect the battery charger during reprogramming work.
VII. CONNECT THE TECHSTREAM ADVi TO THE VEHICLE
NOTICE: In the case of reprogramming, it is an absolute necessity that the vehicle is connected to the Techstream ADVi via the Toyota Supra Diagnostic Cable which has a LAN ethernet connection.
In order to maintain successful communication between the Techstream ADVi and the vehicle, the Toyota Supra Diagnostic cable must be used. Other interfaces that connect to the Techstream ADVi via USB are not allowed. Attempting to use such other devices may cause permanent ECU damage due to the slower communication speed.
1. Connect the Cable (connection sequence):
Always connect the SUPRA diagnostic cable first to your PC LAN port (1) and only after that to the OBD port of the vehicle (2).
If this order of operations is not respected, possible vehicle communication issues may occur when using Toyota ISTA software.
2. Position the cable.
Position the SUPRA diagnostic cable out of the vehicle as shown in the illustration. Otherwise the SUPRA diagnostic cable may be pinched, communication disconnected, and ECU’s permanently damaged.
The Toyota Supra Diagnostic cable should always be passed through the position shown in the figure below. If it passes through any other position it is possible that the cable will be damaged.
Using the gap between the rear fender and the side garnish, pull the Supra Diagnostic cable to the outside of the vehicle. Please use protective tape for fixation and protection of the cable.
Do not attempt to pass the Supra Diagnostic cable thought the window opening. The window glass may move during reprogramming or initialization.
Ensure the cable is out of the path of the front Driver’s seat. During initialization the driver’s seat moves and could damage cable or disconnect the OBDII connector during movement.
Additionally, do not attempt to pass the Supra Diagnostic cable through any other position of the door opening as it may cause damage to the cable.
