OUTPUT OF DIAGNOSTIC CODES
To obtain an output of diagnostic codes, proceed as follows:

1 Initial conditions
a. Battery voltage above 11 volts.
b. Throttle valve fully closed (throttle position sensor IDL points closed).
c. Transmission in neutral position.
d. Accessory switches OFF.
e. Engine at normal operating temperature.

2. Turn the ignition switch to ON. Do not start the engine.






3. Using SST connect terminals TE1 and E1 of the check connector located near the No.2 relay block.

SST: 09843-18020

HINT: The check connector is located near the No. 2 relay block.






4. Read the diagnostic code as indicated by the number of flashes of the "CHECK ENGINE" warning light.






a. Normal System Operation
The light will blink 2 times per second.






b. Malfunction Code Indication
The light will blink a number of times equal to the malfunction code indication as follows:
1. Between the first digit and second digit, 1.5 seconds.
2. Between code and code, 2.5 seconds.
3. Between all malfunction codes, 4.5 seconds.

The diagnostic code series will be repeated as long as the check connector terminals TE1 and E1 are connected.

HINT: In event of a number of trouble codes, indication will begin from the small value and continue to the larger in order.






c. 2 Trip Detection Logic
The diagnostic codes 21, 25, 26, 27 and 71 use "2 trip detection logic". With this logic, when a logic malfunction is first detected, the malfunction is temporarily stored in the ECU memory. If the same case is detected again during the second drive test, this second detection causes the "CHECK ENGINE" Warning Light to light up.

The 2 trip repeats the same mode a 2nd time. (However, the IG SW must be turned OFF between the 1st time and 2nd time).


5. After the diagnosis check, remove the SST.

DIAGNOSIS INDICATION
1. When 2 or more codes are indicated, the lowest number (code) will appear first.

2. All detected diagnostic codes, except for code No 51 and No.53, will be retained in memory by the ECU from the time of detection until cancelled out.

3. Once the malfunction is cleared, the "CHECK ENGINE" warning light on the instrument panel will go off but the diagnostic code(s) remain stored in ECU memory (except for code 51 and 53).
