Test Mode Procedure





MF1A TRANSFER / 4WD / AWD: ACTIVE TORQUE CONTROL 4WD SYSTEM: TEST MODE PROCEDURE

1. DESCRIPTION

HINT
When using a chassis dynamometer, brake tester, etc. to perform a vehicle test, activate test mode to avoid a "different tire diameter installed" incorrect judgment.

Test mode does not have an AWD parameter. Test mode is activated because it will prohibit a different tire diameter judgment.





2. ACTIVATE TEST MODE

HINT
Activate test mode before using a chassis dynamometer, brake tester, etc. to perform a vehicle test.

(a) Check that the ignition switch is off.

(b) Use either of the following methods to change the 4WD control ECU to test mode.

(1) Test mode activation by shorting the TS terminal

* With the ignition switch off, connect the TS and CG terminals of the DLC3 connector. Then turn the ignition switch to ON to activate test mode.

NOTICE:
* When the ignition switch is turned from off to ON, the AWD warning light will illuminate for 4 seconds. Then it will turn off.
* If a part of the active torque control 4WD system has a defect, the AWD warning light will illuminate.

(c) Check if the AWD warning light has changed to the test mode display.

(d) Start the engine.
