4WD Control System Operation Inspection

NOTE:

- If it is difficult to shift between "4H" and "4H-lock" while vehicle is moving, stop vehicle and operate transfer switch.
- The transfer does not shift from "4H" to "4H-lock" ("4H-lock" to "4H") until completing ABS operation.
- Transfer position indicator blinks during shifting process.
- Transfer position indicator blinks and warning buzzer sounds during "N" position at intervals of 3 seconds.
- When the transfer does not shift to "N" or "4L-lock", try the following procedure.

- For M/T model, shift transmission to N (Neutral) position, turn ignition switch to ON position, depress clutch pedal and brake pedal while engine is running, and then try shifting again.
- For A/T model, turn ignition switch to ON position, move vehicles slowly back or forth a few feet, depress brake pedal, and then try shifting again.

1) Inspect shift operation from 4H to 4H-lock as follows.
a) Start engine.
b) Position front wheels straight ahead.
c) Confirm that vehicle is under following conditions.
- Transfer shift position is 4H.
- Vehicle speed is less than 100 km/h (60 mph).
d) Turn transfer switch to "4H-lock" position.
e) Check that differential lock indicator blinks, and then comes ON steady.

2) Inspect shift operation from 4H-lock to 4L-lock as follows.
a) Stop vehicle completely with engine running.
b) Position front wheels straight ahead.
c) Confirm that vehicle is under following conditions.
- Transfer shift position is 4H-lock.
- Transmission shift lever is at "N" position. (A/T model)
- Clutch pedal is depressed fully. (M/T model)
- Brake pedal is depressed.
d) Push and turn transfer switch to "4L-lock" position.
e) Check that 4L indicator blink, and then differential lock indicator and 4L indicator comes ON steady.
3) Inspect shift operation from 4L-lock to 4H-lock as follows.
a) Stop vehicle completely with engine running.
b) Position front wheels straight ahead.
c) Confirm that vehicle is under following conditions.
- Transfer shift position is 4L-lock.
- Transmission shift lever is at "N" position. (A/T model)
- Clutch pedal is depressed fully. (M/T model)
- Brake pedal is depressed.
d) Push and turn transfer switch to "4H-lock" position.
e) Check that 4L indicator blink, and then differential lock indicator comes ON steady and 4L indicator not come ON.

4) Inspect shift operation from 4H-lock to 4H as follows.
a) Start engine.
b) Position front wheels straight ahead.
c) Confirm that vehicle is under following conditions.
- Transfer shift position is 4H-lock.
- Vehicle speed is less than 100 km/h (60 mph).
d) Turn transfer switch to "4H" position.
e) Check that differential lock indicator blinks, and then not comes ON.
5) Inspect shift operation from 4H to N as follows.
a) Stop vehicle completely with engine running.
b) Position front wheels straight ahead.
c) Confirm that vehicle is under following conditions.
- Transfer shift position is 4H.
- Transmission shift lever is at "N" position. (A/T model)
- Clutch pedal is depressed fully. (M/T model)
- Brake pedal is depressed.
d) Turn transfer switch to "square" position (1), keep it there for about 10 seconds, and then turn it to "N" position after N indicator blinks.





e) Check that N indicator blinks and warning buzzer sounds, and then N indicator comes ON steady.
