Transfer Case: Service Precautions
Transfer WarningWARNING:
This transfer has a center differential.
When testing with 2-wheel chassis dynamometer or speedometer tester (which tester roller is driven by vehicle wheels), be sure to make the vehicle as rear wheel drive or as front wheel drive temporarily as follows.
Otherwise, front wheels drive rear wheels or vise-versa and personal injury may result.
1. Remove front propeller shaft or rear propeller shaft.
2. Install special tool (cap) to flange yoke cover hole (front or rear) of transfer (1) and fix it to transfer or hook with string to prevent oil leakage from transfer.
3. Pour specified oil into transfer up to lever plug hole if front propeller shaft is removed.
4. Shift transfer to 4H-lock position as follows.
^ Non-shift type (Transfer without shift actuator)
- Remove lever bolt (1) on transfer, push down lever to 4H-lock position (2) and fix lever with bolt.
^ Motor-shift type (Transfer with shift actuator)
- Shift transfer to 4H-lock position by turning transfer switch.
Precautions in Diagnosing Trouble
^ Do not disconnect the following parts before confirming diagnostic information (DTC, etc.) stored in 4WD control module memory. These actions will erase memorized information in 4WD control module memory.
- Disconnection of coupler from 4WD control module
- Disconnection of battery cable from battery
- Disconnection of ground wire harness of 4WD control module
- Disconnect main fuse from fuse box
^ Diagnostic information stored in 4WD control module memory can be cleared as well as checked by using SUZUKI scan tool. Before using scan tool, read its Operator's (Instruction) Manual carefully to have good understanding as to what functions are available and how to use it.
^ Be sure to read "Precautions for Electrical Circuit Service:" before inspection and observe what is written there.
