With Manufacturer's Scan Tool

a. Check the TEM output (LED lighting 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 using the hand-held tester:

Check the DTC.

1. Hook up the hand-held tester to the DLC3.
2. Turn the ignition switch to ON.
3. Read the DTC by following the prompts on the tester screen.

HINT: Please refer to the hand-held tester operator's manual for further details.
