CM and 4WD solenoid, then go to Step 9.
No Go to next step.
4INSPECT 4WD SOLENOID TO 4WD CM
(GROUND CIRCUIT) FOR OPEN CIRCUIT
•Inspect for continuity between 4WD CM
terminal P and 4WD solenoid terminal A.
•Is there continuity?Yes Replace 4WD CM, then go to next step.
No Repair or replace harness for open circuit between 4WD CM
and 4WD solenoid, then go to Step 9.
5INSPECT 4WD CM POWER SUPPLY CIRCUIT
FOR OPEN CIRCUIT

K and ground.
•Is voltage B+?Yes Replace 4WD CM, then go to Step 9.
No Go to next step.
6INSPECT 4WD CM TO BATTERY FOR OPEN
CIRCUIT
•Disconnect 4WD CM connector and battery
positive terminal.
•Inspect for continuity between 4WD CM
terminal K and battery positive terminal.
•Is there continuity?Yes Go to next step.
No Repair or replace harness for open circuit between 4WD CM
and battery positive terminal, then go to Step 9.
7INSPECT 4WD CM TO BATTERY FOR SHORT
TO GROUND
•Inspect for continuity between 4WD CM
terminal K and ground.
•Is there continuity?Yes Repair or replace harness for short to ground between 4WD
CM and battery positive terminal, then go to Step 9.
No Replace 4WD CM, then go to step 9.
8INSPECT FUSE CONDITION
•Turn ignition key to OFF.
•Is ENG+B fuse (10A) okay?Yes Go to next step.
No Replace fuse, then go to Step 9.
9VERIFY TROUBLESHOOTING COMPLETED
•Make sure to reconnect all disconnected
connectors.
•Clear DTC from memory.
(See M–76 Clearing DTCs Procedures)
•Drive vehicle.
•Is the same DTC present?Yes Replace 4WD CM, then go to next step.
No Go to next step.
10VERIFY AFTER REPAIR PROCEDURE
•Is there any other DTC present?Yes Go to applicable DTC inspection.
No Troubleshooting completed. STEP INSPECTION ACTION

DTC P1888A6E637027100204
Diagnostic procedure
DTC P1888 Differential oil temperature sensor
DETECTION
CONDITION•Differential oil temperature sensor voltage monitor circuit detects abnormal input voltage.
POSSIBLE
CAUSE•Open circuit, or short to battery or GND between 4WD CM terminal A and differential oil temperature
sensor terminal A
•Open circuit or short to battery between 4WD CM terminal C and differential oil temperature sensor
terminal B
•Differential oil temperature sensor malfunction
•4WD CM malfunction
•Poor connection of connectors (female terminals)
STEP INSPECTION ACTION
1INSPECT DIFFERENTIAL OIL
TEMPERATURE SENSOR CONDITION
•Turn ignition key to OFF.
•Disconnect differential oil temperature
sensor connector.
•Is it okay?Yes Go to next step.
No Replace differential oil temperature sensor, then go to Step
7.
2INSPECT 4WD CM TO DIFFERENTIAL OIL
TEMPERATURE SENSOR FOR OPEN
CIRCUIT
•Disconnect 4WD CM connector.
•Inspect for continuity between 4WD CM
terminal A and differential oil temperature
sensor terminal A.
•Is there continuity?Yes Go to next step.
No Repair or replace harness for open circuit between 4WD CM
and differential oil temperature sensor, then go to Step 7.
3INSPECT 4WD CM TO DIFFERENTIAL OIL
TEMPERATURE SENSOR FOR SHORT TO
POWER
•Inspect voltage between 4WD CM terminal A
and ground.
•Is voltage B+?Yes Repair or replace harness for short to power between 4WD
CM and differential oil temperature sensor, then go to Step
7.
No Go to next step.
