On-Board Diagnostics System

FUNCTION
The self-diagnosis system is capable of detecting any trouble which has occurred in any of the following input and output signal systems:

^ Vehicle speed sensor 1
^ Vehicle speed sensor 2
^ Throttle sensor
^ Shift solenoid 1
^ Shift solenoid 2
^ Shift solenoid 3
^ Duty solenoid B
^ Duty solenoid C (AWD only)
^ ATF temperature sensor
^ Ignition pulse
^ Duty solenoid A

The results of self-diagnosis are displayed by flashing power indicator lamp:

^ Repeated flashing at 4 Hz: error such as battery trouble.
^ Repeated flashing at 2 Hz: normal
^ Output of trouble code: check faulty component
^ Lamp continuously lit: error in inhibitor switch, manual switch, idle switch, or wiring

OPERATION OF INDICATOR LAMP

Power Indicator Malfunction Display:

When any on-board diagnostic item is malfunctioning, the power indicator light blinks immediately after the engine starts. If there is no problem, the light goes out approximately 2 seconds after engine start. The malfunctioning part or unit can be determined by a trouble code during on-board diagnostic operation. Problems which occurred previously can also be identified through the memory function. If the power indicator does not show a problem (although a problem is occurring), the problem can be determined by checking the performance characteristics of each sensor using the Select Monitor or equivalent.
