TERMINAL LAYOUT
PHYSICAL VALUES
*: The values are changed by throttle opening and engine speed.
CAUTION:
When using circuit tester to measure voltage for inspection, be sure not to
extend forcibly any connector
terminals.
Fail-safe
When a system malfunction occurs, the 4WD warning lamp turns ON and the 4WD control becomes 2WD state.
Protection Function
4WD system activates its protection function (shuts down 4WD system temporarily) if 4WD system detects high load continuously, the front wheel tire size differs from the rear tire size or the rear RH wheel tire size differs from the rear LH tire size. (4WD system is automatically restored if 4WD system no longer detects any overload or the tire size difference is eliminated.)
*1: 2 times/second (blinking for approximately 1 minute and then turned
OFF)
*2: 1 time/2 seconds (continuing to blink until ignition switch is turned OFF)
NOTE
:
• If the warning lamp blinks slowly during driving but remains OFF after the
engine is restarted, the system is
normal. If it again blinks slowly after driving for some time, vehicle must be
inspected.
• When there is a difference of revolution speed between the front and rear wheel the shift occasionally changes to direct 4-wheel driving conditions automatically. This is not a malfunction.
