STOP AND START STOP AND START SYSTEM Neutral Position Switch Circuit
DESCRIPTION
The engine stop and start ECU uses the shift lever position sensor installed to the continuously variable transaxle assembly to detect when the shift lever is in P or N.

CAUTION / NOTICE / HINT
- NOTICE:
- ·
Before replacing the engine stop and start ECU, read the number of starter operations and write it into a new engine stop and start ECU.
·After replacing the engine stop and start ECU or air conditioning amplifier assembly, reset and perform learning of the air conditioning information in the engine stop and start ECU.
·After replacing the engine stop and start ECU or airbag ECU assembly, clear and calibrate the deceleration sensor zero point in the engine stop and start ECU.
·Bleed the oil pump with motor assembly (continuously variable transaxle assembly) after removing and installing the continuously variable transaxle assembly or replacing the CVT fluid.
