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 a 4WD 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 engine switch is off.

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

(1) Test mode activation by shorting TS terminal

* With the engine switch off, connect the TS and CG terminals of the DLC3 connector. Then turn the engine switch on (IG) to activate test mode.

HINT
When the engine switch is on (IG) and the 4WD lock switch is turned from OFF to ON, the 4WD lock indicator blinks twice and then illuminates.

NOTICE:
If a part of the 4WD system has a defect, the Master warning light will illuminate.

(c) Check if the combination meter has changed to the test mode display.

(d) Start the engine.

3. CONFIRM MODE CHANGE
