4WD Control System Operation Inspection
4WD Control System Operation InspectionNOTE:
^ If it is difficult to shift between "4H" and "4H-lock" while vehicle is moving, stop vehicle and operate Transfer switch.
^ When ABS operates while shifting from "4H" to "4H-lock" ("4H-lock" to "4H"), it becomes to disagreement of transfer switch and transfer position. End of the ABS operation, and then transfer shifting from "4H" to "4H-lock" ("4H-lock" to "4H").
^ Transfer position indicator blinks during shifting process.
^ Transfer position indicator blinks and warning buzzer sounds during "N" position at intervals of 3 seconds.
^ When shifting to "N" or "4L lock" does not shifts, 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 lowly 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. (for A/T model)
^ Clutch pedal is depressed fully. (for 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. (for A/T model)
^ Clutch pedal is depressed fully. (for 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. (for A/T model)
^ Clutch pedal is depressed fully. (for M/T model)
^ Brake pedal is depressed.
d. Turn transfer switch to "D" 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.
