DIAGNOSIS INSPECTION (NORMAL MODE)MALFUNCTION INDICATOR LAMP CHECK
1. THE MALFUNCTION INDICATOR LAMP WILL COME ON WHEN THE IGNITION SWITCH IS TURNED ON AND THE ENGINE IS NOT RUNNING.
- If the malfunction indicator lamp does not light up, proceed to troubleshooting of the combination meter.
2. WHEN THE ENGINE IS STARTED, THE MALFUNCTION INDICATOR LAMP SHOULD GO OFF.
- If the lamp remains ON, the diagnosis system has detected a malfunction or abnormality in the system.
DIAGNOSTIC TROUBLE CODE CHECK
1. TURN IGNITION SWITCH ON.
2. USING A JUMPER WIRE (or SST 09843-18020), CONNECT TERMINALS BETWEEN TE1 AND E1 OF DATA LINK CONNECTOR (DLC1).
3. READ THE DIAGNOSTIC TROUBLE CODE FROM MALFUNCTION INDICATOR LAMP.
- As an example, the blinking patterns for codes; normal, 12 and 31 are as shown on the illustration.
- In the event of 2 or more malfunction codes, indication will begin from the smallest numbered code and continue in order to the largest.
HINT: If a diagnostic trouble code is not output, check the TE1 terminal circuit.
Refer to the "Non-Trouble Code Charts" under Diagnostic Charts..
4. CHECK THE DETAILS OF THE MALFUNCTION USING THE TABLE UNDER "TROUBLE CODE DESCRIPTIONS", THEN PROCEED TO THE PROPER "TROUBLE CODE CHART" FOUND UNDER DIAGNOSTIC CHARTS.
5. AFTER COMPLETING THE CHECK, TURN THE IGNITION KEY TO OFF AND DISCONNECT TERMINALS TE1 AND E1.
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
1. INITIAL CONDITIONS:
- Battery positive voltage 11 volts or more.
- Throttle valve fully closed.
- Transmission in park or neutral position.
- Air conditioning switch OFF.
2. TURN IGNITION SWITCH OFF.
3. SET THE DIAGNOSIS SYSTEM TO TEST MODE.
- Using a jumper wire (or SST 09843-18020), connect terminals TE2 and E1 of data link connector (DLC1).
4. TURN IGNITION SWITCH ON.
HINTS:
- 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, refer to the "Non-Trouble Code Charts" for the "TE1, TE2 Terminal Circuit" under the Diagnostic Charts.
5. START THE ENGINE.
6. SIMULATE THE CONDITIONS OF THE MALFUNCTION DESCRIBED BY THE CUSTOMER.
7. AFTER THE ROAD TEST, USING A JUMPER WIRE, CONNECT TERMINALS TE1 AND E1 OF DLC1.
8. READ THE DIAGNOSTIC TROUBLE CODE ON MALFUNCTION INDICATOR LAMP ON THE COMBINATION METER.
9. AFTER COMPLETING THE CHECK, DISCONNECT TERMINALS TE1, TE2 AND E1 AND ERASE THE STORED TROUBLE CODES.
NOTES:
^ The test mode will not start if terminals TE2 and E1 are connected after the ignition switch is turned ON.
^ When vehicle speed is 5 km/h (3 mph) or below, diagnostic trouble code "42" (Vehicle speed signal) is output, but this is not abnormal.
^ When the engine is not cranked, diagnostic trouble code "43" (Starter signal) is output, but this is not abnormal.
^ When the automatic transaxle 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.
