1998 NISSAN PATROL lock

4. If shim thickness determined by equation is assumed as ``T'',
``T'' will be expressed by equation ``A'' - ``L''. Select a combina-
tion of shims from those shown in SDS so that shim thickness
is within ``T'' range. Install actuator using selected shims.

System Description
The differential lock operates only in 4WD.
The differential lock control unit interrupts current ¯owing through
differential lock solenoid-2 when vehicle speed exceeds 7 km/h (4
MPH). If the differential lock switch is accidentally turned on when
vehicle speed is greater than 7 km/h (4 MPH), the control unit will
prevent the differential lock from sustaining impact damage.
A warning buzzer will sound when the vehicle is driven over 20
km/h (12 MPH) with the differential lock engaged.

Electrical Components Inspection
DIFFERENTIAL LOCK INDICATOR SWITCH CHECK
+Check switch function by checking continuity.
Continuity:
ON Continuity should exist.
OFF Continuity should not exist.
If NG, replace differential lock indicator switch.
DIFFERENTIAL LOCK SOLENOID CHECK
1. Disconnect differential lock solenoid 4-pin connector.
2. Check continuity between terminals
V1andV3,V2andV4.
Continuity should exist.
If NG, replace differential lock solenoid.
SPEED SENSOR CHECK
Refer to EL section.
