DTC P1880	RFW Free solenoid valve circuit/short to battery
DETECTION CONDITION	• Short to power circuit has been detected in the Free solenoid valve wiring harness.
POSSIBLE CAUSE	• Free solenoid valve malfunction • Connector or terminal malfunction • Short to power supply in wiring harness between Free solenoid valve terminal B and PCM terminal 254 • PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT FREE SOLENOID VALVE CONNECTOR FOR POOR CONNECTION • Turn the engine switch off. • Disconnect the Free solenoid valve connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 5.
1		No	Go to the next step.
2	INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the engine switch off. • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 5.
2		No	Go to the next step.
3	INSPECT FREE SOLENOID VALVE CIRCUIT SHORT TO POWER SUPPLY • Turn the engine switch to the ON position (Engine off). • Measure the voltage between the following circuits: ― Free solenoid valve terminal B (wiring harness-side) and body ground • Is the voltage B+?	Yes	Repair or replace the wiring harness for short to power supply, then go to the Step 5.
3		No	Go to the next step.
4	INSPECT FREE SOLENOID VALVE • Inspect the Free solenoid valve. (See LOCK AND FREE SOLENOID VALVES INSPECTION.) • Is there any malfunction?	Yes	Replace the Free solenoid valve, then go to the next step.
4		No	Go to the next step.
5	VERIFY TROUBLESHOOTING OF DTC P1880 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. • Start the engine. • Shift the transfer select lever. • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [WL-C, WE-C].) (See PCM REMOVAL/INSTALLATION (U.K. Specs.) [WL-C, WE-C].)
5		No	Go to the next step.
6	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure“. (See AFTER REPAIR PROCEDURE [WL-C, WE-C (Thailand, General (L.H.D. R.H.D.) specs.)].) (See AFTER REPAIR PROCEDURE [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)].) • Are any DTCs present?	Yes	Go to the applicable DTC troubleshooting. (See DTC TABLE [WL-C, WE-C (Thailand, General (L.H.D. R.H.D.) specs.)].) (See DTC TABLE [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)].)
6		No	Troubleshooting completed.
