OUTPUT OF DIAGNOSTIC CODESTo obtain an output of diagnostic codes, proceed as follow:
1. Initial conditions
(a) Battery voltage 11 V or more
(b) Throttle valve fully closed (throttle position sensor IDL points closed)
(c) Transmission in neutral position
(d) Accessories switched OFF
(e) Engine at normal operating temperature
2. Turn the ignition switch to ON. Do not start the engine.
3. Using a service wire, connect terminals TE1 and E1 of the check connector.
4. Read the diagnostic code as indicated by the number of flashes of the "CHECK" engine warning light.
(a) Normal System Operation (no malfunction)
^ The light will alternately blink ON and OFF 2 times per second.
(b) Malfunction Code Indication
^ In the event of a malfunction, the light will blink every 0.5 seconds. The first number of blinks will equal the first digit of a 2-digit diagnostic code and, after a 1.5 second pause, the 2nd number of blinks will equal the 2nd. If there are two or more codes, there will be a 2.5 second pause between each.
^ After all the codes have been signalled there will be a 4.5 second pause and they will all be repeated as long as the terminals TE1 and E1 of the check connector are shorted.
NOTE:
^ In the event of a number of trouble codes, indication will begin from the smaller value and continue in order to the larger.
5. After the diagnostic check, remove the service wire.
