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.

DIAGNOSTICS CHART

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.
