DLN-228 < DTC/CIRCUIT DIAGNOSIS > [REAR FINAL DRIVE: M226 (ELD) ] P1848 SOLENOID DISCONNECT P1848 SOLENOID DISCONNECT Description INFOID:0000000009886130 When power and ground is supplied from the differential lock control unit, the differential lock solenoid will actuate to move the pressure plate against the cam ring to lock the differential. By reversing polarity at the dif- ferential lock control unit, the differential lock solenoid moves the pressure plate away from the cam ring to unlock the differential. DTC Logic INFOID:0000000009886131 Diagnosis Procedure INFOID:0000000009886132 Regarding Wiring Diagram information, refer to 1. CHECK DIFFERENTIAL SOLENOID CONTROL 1. Start engine. 2. Using CONSULT, select “RELAY ON”, “RELAY MTR”, “SOL MTR” of DIFF LOCK data monitor. 3. Observe the display values while operating the differential lock system. Is the inspection result normal? YES >> Differential lock solenoid control system is operating normally. NO >> GO TO 2. 2. CHECK DIFFERENTIAL LOCK SOLENOID RESISTANCE 1. Turn ignition switch OFF. 2. Disconnect differential lock solenoid connector. 3. Check resistance between differential lock solenoid terminals 2 and 4. Is the inspection result normal? YES >> GO TO 3. NO >> Replace differential lock solenoid. 3.
