IDLE NEUTRAL CONTROL : System Description

INFOID:0000000009019867

SYSTEM DIAGRAM

DESCRIPTION

If a driver has no intention of starting the vehicle in D position, TCM operates the low brake solenoid valve and

controls the oil pressure of the low brake to be low pressure. Therefore, the low brake is in the release (slip)

status and the power transmission route of transaxle is the same status as the N position. In this way, the tran-

saxle is in idling status and load to the engine can be reduced to improve fuel economy.

ON BOARD DIAGNOSTIC (OBD) SYSTEM

Description

INFOID:0000000009019870

This is an on board diagnosis system which records diagnosis information related to the exhaust gases. It

detects malfunctions related to sensors and actuators. The malfunctions are indicated by means of the mal-

function indicator lamp (MIL) and are stored as DTC in the ECU memory. The diagnosis information can be

checked using a diagnosis tool (GST: Generic Scan Tool).

Function of OBD

INFOID:0000000009019871

The GST is connected to the diagnosis connector on the vehicle and communicates with the on-board control

units to perform diagnosis. The diagnosis connector is the same as for CONSULT. Refer to 

GI-49, "Descrip-

tion"
