PROCEDURENormal Mode
1. Turn Ignition Switch ON.
2. Using jumper, connect terminals between TE1 and E1 of Data Link Connector 1 or 2 (SST 09843-18020).
3. Read the Diagnostic Trouble Code from Malfunction Indicator Lamp. In the event of 2 or more malfunction codes, indication will begin from the smaller numbered code and continue in order to the larger. As an example, the blinking patterns for codes; 12 and 31 are as shown in the illustration.
NOTE: If a Diagnostic Trouble Code is not output, check the TE1 terminal circuit.
4. Check the details of the malfunction by refering to Diagnostic Trouble Code Descriptions.
5. After completing the check, disconnect terminals TE1 and E1, and turn off the display.
Test Mode
Compared to the normal mode, the test mode has high 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.
1. Verify initial conditions;
- Battery voltage 11 volts or more.
- Throttle valve fully closed (Throttle Position Sensor IDL points closed).
- Transmission in neutral position.
- Air conditioning switched off.
2. Turn Ignition Switch OFF.
3. Using jumper, connect terminals TE2 and E1 of Data Link Connector 2. (SST 09843-18020)
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.
5. Start the engine.
6. Simulate the conditions of the malfunction described by the customer.
7. After the road test, using jumper, connect terminals TE1 and E1 of Data Link Connector 1 Or 2 (SST 09843-18020).
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 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 Codes "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.
