DTC Description DTC Freeze Frame C1852-19 Solenoid Valve Circuit High Current Is DTC C1852-19 indicated?
YES
The failure is duplicated. Go to step 3.
NO
Intermittent failure, the system is OK at this time. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.
- Shorted wire check (DTYH line)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Disconnect the following connectors.
Rear differential solenoid valve 1P connector AWD control unit 24P connector -3. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Rear differential solenoid valve 1P connector: disconnected AWD control unit 24P connector: disconnected Test point 1 AWD control unit 24P connector No. 15 Test point 2 Body ground Is there continuity?
YES
Repair a short to ground in the DTYH wire between the rear differential solenoid valve and the AWD control unit.
NO
The DTYH wire is OK. Go to step 4.
- Rear differential solenoid valve check
-1. Turn the vehicle to the ON mode.
-2. Check the parameter(s) below with the HDS.
NOTE: The rear differential fluid temperature should be 50 deg.F (10 deg.C) - 86 deg.F (30 deg.C). If the value is not within the enable temperature, warm up the rear differential fluid temperature by raising the vehicle on a lift and run the vehicle at speeds 12 mph (20 km/h) for 5 seconds then slow down, and stop the wheels.
Signal Current conditions Values Unit Oil temperature for rear differential -3. Turn the vehicle to the OFF (LOCK) mode.
-4. On the solenoid valve side, measure the resistance between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Rear differential solenoid valve 1P connector: disconnected AWD control unit 24P connector: disconnected Test point 1 Rear differential solenoid valve 1P connector (male terminals) No. 1: Test point 2 Body ground Is there about 10 ohms or more?
YES
The rear differential solenoid valve is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting or substitute a known-good AWD control unit , then recheck. If this DTC goes away and the AWD control unit was substituted, replace the original AWD control unit .
NO
