Repair Instruction: Initialization: Initialization

PROCEDURES NECESSARY WHEN BATTERY TERMINAL IS DISCONNECTED/RECONNECTED

Necessary Procedures	Effect / Inoperative Function When Necessary Procedures are not Performed	See
Correct the steering angle neutral point	Advance parking guidance system	Refer to INITIALIZATION

NOTE:

When the auxiliary battery is replaced or the cable is disconnected from its negative (-) battery terminal, the ISC learning value will be initialized and symptoms as a loud rattle from the hybrid vehicle transaxle assembly may occur until ISC learning is performed. Therefore, perform ISC learning when the auxiliary battery is replaced or the cable is disconnected from the negative (-) terminal of the auxiliary battery. Refer to Loud Rattle from Hybrid Vehicle Transmission .
