For the ECU to be able to save ratios and ESC EOL data, the ignition
MUST be cycled. With the vehicle stopped, close window that
appeared and cycle the ignition for around 10 seconds.
NOTE:
Power down cycle time and sequence will vary amongst
vehicle manufacturers. Some vehicles might require the key to be
removed from the ignition for ignition power to be completely turned
off. Please follow the vehicle manufacturer procedure to make sure
ignition is turned off.
When the ignition is turned back ON, check that no active or stored
faults are logged in the ECU and that the ABS and ATC/ESC warning
lamps are OFF. Figure 9.19 and Figure 9.20.

The ESC EOL Initialization procedure is completed.
NOTE:
If ESC EOL initialization was not properly completed and/or
ratios correctly saved, code SID 88 FMI 1 will be active. Follow the
ESC initialization again and make sure each portion is successfully
completed. Make sure ignition power down is completed for the ECU
to successfully save data.
