DIAGNOSTIC TROUBLE CODE CHECK (NORMAL MODE)
1. Turn ignition switch ON.







2. Using SST 09843-18020, connect terminals between TE1 and E1 of data link connector 1 or 2.




3. Read the diagnostic trouble code from Malfunction Indicator Lamp.

HINT: If a diagnostic trouble code is not output, check the TE1 terminal circuit.




As an example, the blinking patterns for codes; normal, 12 and 31 are as shown on the illustration.

4. Check the details of the malfunction using the diagnostic trouble code chart.
5. After completing the check, disconnect terminals TE1 and E1, and turn OFF the display.

HINT: In the event of 2 or more malfunction codes, indication will begin from the smaller numbered code and continue in order to the larger.




DIAGNOSIS INSPECTION (TEST MODE)
Compared to the normal mode, the test mode has an increased sensing ability to detect malfunctions.
It can also detect malfunctions in the starter signal circuit, the IDL contact signal of the throttle position sensor, air conditioning signal and park/neutral position switch signal.
Furthermore, the same diagnostic items which are detected in the normal mode can also be detected in the test mode.




DIAGNOSTIC TROUBLE CODE CHECK IN TEST MODE
1. Initial conditions.
- Battery voltage 11 V or more
- Throttle valve fully closed
- Transmission in neutral position
- Air conditioning switch OFF
2. Turn ignition switch OFF.
3. Using SST 09843-18020, connect terminals TE2 and E1 of data link connector 1 or 2.




4. Turn ignition switch ON.

HINT:
- To confirm that the test mode is operating, check that the Malfunction Indicator Lamp flashes when the ignition switch is turned to ON.
- If the Malfunction Indicator Lamp does not flash, proceed to troubleshooting of the TE2 terminal circuit.

5. Start the engine.
6. Simulate the conditions of the malfunction described by the customer.
7. After the road test, using SST 09843-18020, connect terminals TE1 and E1 of data link connector 1 or 2.







8. Read the diagnostic trouble code on Malfunction Indicator Lamp in the combination meter.
9. After completing the check, disconnect the SST from terminals TE1, TE2 and E1, and turn off the display.

HINT:
- The test mode will not start if terminals TE2 and E1 are connected after the ignition switch is turned ON.
- When the engine is not cranked, diagnostic trouble code "43" (Starter signal) is output, but this is not abnormal.
- When the automatic transmission shift lever is in the "D", "2", "L" or "R" shift position, or when the air conditioning is ON or when the accelerator pedal is depressed, code "51" (Switch condition signal) is output, but this is not abnormal.
