2. | If you need to replace the resolver sensor, replace the HSG assembly. (Refer to Hybrid Motor Assembly - "Hybrid Starter Generator".) |
You need to perform resolver compensation whenever the engine, HPCU (inverter), drive motor, or starter generator (HSG) is replaced, removed, or reinstalled. Perform compensation according to the GDS motor/HSG resolver compensation procedure shown below. |
GDS Motor / HSG Resolver Compensation Procedure
Description•
Motor temperature affects the motor power significantly.•
If the motor overheats, its main components, including permanent magnet, stator coil, etc...

Check Lane Keeping Assist (LKA) system
If there is a problem with the system a message will appear for a few seconds.
If the problem continues the LKA system failure indicator will illuminate.
LKA system failure indicator
The LKA system failure indicator (yellow) will illuminate if the LKA system is
not working properly...
Checking the Brake Fluid Level
Check the fluid level in the reservoir periodically. The fluid level should be
between MAX and MIN marks on the side of the reservoir.
Before removing the reservoir cap and adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent brake fluid contamination...
