Test Mode

DESCRIPTION
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.


DIAGNOSTIC TROUBLE CODE CHECK
- Initial conditions.

- Battery positive voltage 11 V or more.
- Throttle valve fully closed (throttle position sensor IDL points closed).
- Transmission in neutral position.
- Air conditioning switched off.

- Turn ignition switch off.

Installing Jumper - Test Mode:

- Using a suitable jumper wire, connect terminals TE2 and El of DLC2.
- 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, troubleshoot the TE2 terminal circuit.

- Start the engine.
- Simulate the conditions of the malfunction described by the customer.

Extracting Codes - Test Mode:

- After the road test, using a suitable jumper wire, connect terminals TE1 and E1 of DLC2 or DLC1.
- Read the diagnostic trouble code on malfunction indicator lamp on the combination meter.
- After completing the check, disconnect terminals TE1, TE2 and El, 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, diag. trouble codes "43" (Starter signal) 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.
