During tests using a brake tester or chassis dynamometer, such as braking force tests or speedometer tests, if only the front or rear wheels are to be rotated, it is necessary to set the position of the center differential to FREE or LOCK depending on the type of test being performed. Center differential FREE condition: agn ITEM CONDITION WHEEL Center differential switch OFF A lifted wheel cannot be rotated even if only one wheel is lifted up, as long as transmission is in N position Indicator light OFF Transfer select lever (H/L) w/ VSC: H or L position w/o VSC: H position only Center differential LOCK conditions (w/ VSC):
ITEM CONDITION WHEEL Center differential switch ON A lifted wheel cannot be rotated even if only one wheel is lifted up, as long as transmission is in N position Indicator light ON Transfer select lever (H/L) H or L position Center differential LOCK conditions (w/o VSC): ITEM CONDITION WHEEL Center differential switch ON A lifted wheel cannot be rotated even if only one wheel is lifted up, as long as transmission is in N position Indicator light ON Transfer select lever (H/L) H position Transfer select lever (H/L) L position HINT: w/o Vehicle Stability Control (VSC) system:
When the transfer select lever is put in the "L" position, the center differential is put in the LOCK condition regardless of the position of the center differential lock switch. CAUTION: Center differential "LOCK" ←→ "FREE" selecting procedure: Operate the switch only when all 4 wheels are stopped or driven in a straight line. Never operate the switch when any wheel is slipping. Never operate the switch when any wheel is spinning freely. Never operate the switch when swerving or cornering. HINT: Center differential "LOCK" ←→ "FREE" selecting procedure:
Move the vehicle forward or backward slightly if the indicator light does not operate correctly when the center differential lock switch is turned ON or OFF. cardi
