DTC (Real Time AWD)
- Problem verification (with engine idling)
-1. Turn the vehicle to the ON mode.
-2. Clear the DTC with the HDS.
-3. Turn the vehicle to the OFF (LOCK) mode.
-4. Start the engine.
-5. Check for DTCs with the HDS.
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
Go to step 2.
- Problem verification (with rear differential pump motor running)
-1. Clear the DTC with the HDS.
-2. Turn the vehicle to the OFF (LOCK) mode.
-3. Turn the vehicle to the ON mode.
-4. Select the ADJUSTMENT in the REAL TIME AWD with the HDS.
-5. With the engine running, do the AIR BLEEDING in the ADJUSTMENT with the HDS .

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 (DTYH1 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 DTYH1 wire between the rear differential solenoid valve and the AWD control unit.
NO
The DTYH1 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 13 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 Ω or more?
YES
Check for any authorized service information related to the DTCs or symptoms you are troubleshooting or substitute a known-good AWD control unit , and recheck. If the symptom/indication goes away with a known-good AWD control unit, replace the original AWD control unit .
NO
