On-board Diagnostics System: Function

The on-board diagnostics system detects and stores in the form of a code a fault that has occurred in any of the following input and output signal systems.

Rear vehicle speed sensor	High clutch duty solenoid	Sports shift switch
Front vehicle speed sensor	Low & reverse duty solenoid	Engine speed signal
Throttle position sensor	Transfer duty solenoid	Lockup clutch
Line pressure linear solenoid	ATF temperature sensor	Torque converter turbine speed sensor
2-4 brake duty solenoid	CAN communication signal circuit	1, 2, 3, 4, R gear ratios
Lockup duty solenoid	Inhibitor switch	Shift lock solenoid
Low clutch duty solenoid	Brake switch

If a fault has been detected, the system tells the fault by causing the SPORT indicator light to blink.
