Without Scan Tool

a. Check the TEM output (LED lightning check).

1. Connect the LED and resistor in series between terminals TEM and CG of the DLC3.

NOTE: If connected reversely, the LED does not light

HINT:
- Use the LED whose recommended operating current is 10 - 20 mA.
- The 500 Ohms to 1 kOhms resistor must be used.

2. Turn the ignition switch to ON, and check that the LED lights for about 2 seconds.

HINT: If the LED does not light, inspect the TEM circuit.

b. In case of not using hand-held tester:

Check the DTC.

1. Check the battery positive voltage.

Battery positive voltage: 10 - 14 V (Engine stopped)




2. After driving the vehicle, using SST, connect terminals Tc and CG of the DLC3.

SST 09843-18040

HINT:
- Do not stop the engine.
- Under this condition, the ignition switch is ON.

NOTE: Wrong connection of the connector may cause a malfunction. With extreme caution, connect the connector.




3. Connect the LED and resistor in series between terminals TEM and CG of the DLC3.







4. Check the number that the LED blinks.

HINT:
- When the code is normal, the LED keeps on for 0.25 seconds and off for 0.25 seconds repeatedly.
- When more than 2 diagnosis codes are detected, the diagnosis codes are displayed in order from the smallest number.
- If no code appears, inspect the Tc circuit.
- Codes are explained in the code table.

5. Turn the ignition switch to ON.

6. Disconnect the SST from terminals Tc and CG of the DLC3.

SST 09843-18040

7. Disconnect the LED and resistor from the terminals TEM and CG of the DLC3.

HINT: Confirm that the connected LED is off.

8. When an abnormal code is output, inspect the function, absorber control ECU and input signal.
