DTC P2047:11 DTC P2047:12 DTC P2047:13 DTC P2047:14 DTC P2047:15	Urea injector valve circuit malfunction (short to ground/short to power supply and open)
DETECTION CONDITION	• The SCR control unit monitors the input signal from the urea injector valve when the ignition is switched ON. The SCR control unit determines that there is a malfunction in the urea injector. Monitoring condition ― Following conditions are met: • Battery voltage: 9—16 V Diagnostic support note • The MIL/SCR warning light illuminates if the SCR control unit detects the above malfunction condition in first drive cycle. • PENDING CODE is available if the SCR control unit detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA (mode2) and snapshot data are available. • The DTC is stored in the SCR control unit memory.
POSSIBLE CAUSE	• Urea injector short cord connector or terminal malfunction • Urea injector malfunction • Short to power supply in wiring harness between urea injector short cord terminal A and SCR control unit terminal 74 • Short to power supply in wiring harness between urea injector short cord terminal B and SCR control unit terminal 91 • Short to ground in the wiring harness between urea injector short cord terminal A and SCR control unit terminal 74 • Short to ground in the wiring harness between urea injector short cord terminal B and SCR control unit terminal 91 • Open circuit in the wiring harness between urea injector short cord terminal A and SCR control unit terminal 74 • Open circuit in the wiring harness between urea injector short cord terminal B and SCR control unit terminal 91 • SCR control unit connector or terminal malfunction • Urea injector connector or terminal malfunction • SCR control unit malfunction

• Short to ground in the wiring harness between urea injector short cord terminal A and SCR control unit terminal 74

• Short to ground in the wiring harness between urea injector short cord terminal B and SCR control unit terminal 91

• Open circuit in the wiring harness between urea injector short cord terminal A and SCR control unit terminal 74

• Open circuit in the wiring harness between urea injector short cord terminal B and SCR control unit terminal 91

• SCR control unit connector or terminal malfunction

• Urea injector connector or terminal malfunction

• SCR control unit malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE2) OR SNAPSHOT DATA HAVE BEEN RECORDED • Have FREEZE FRAME DATA (mode2) or snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (mode2) and snapshot data on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform the repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT? • Connect the M-MDS to the DLC-2. • Clear the DTC from the SCR control unit memory using the M-MDS. • Start the engine. • Is the PENDING CODE for this DTC present?	Yes	Go to the next step.
3		No	Intermittent concern exists. Perform the “INTERMITTENT CONCERN TROUBLESHOOTING”. (See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD 2.2].)
4	INSPECT UREA INJECTOR SHORT CORD CONNECTOR FOR POOR CONNECTION • Switch the ignition off. • Disconnect the urea injector short cord connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 11.
4		No	Go to the next step.
5	INSPECT UREA INJECTOR • Inspect the urea injector. (See SCR SYSTEM INSPECTION [MZR-CD 2.2].) • Is there any malfunction?	Yes	Replace urea injector, then go to Step 11. (See UREA INJECTOR REMOVAL/INSTALLATION [MZR-CD 2.2].)
5		No	Go to the next step.
6	INSPECT UREA INJECTOR CIRCUIT FOR SHORT TO POWER SUPPLY • Switch the ignition off. • Measure the voltage between the following terminals: ― Urea injector short cord terminal A and body ground. ― Urea injector short cord terminal B and body ground. • Is the voltage B+?	Yes	Repair or replace the malfunctioning wiring harness, then go to Step 11.
6		No	Go to the next step.
7	INSPECT UREA INJECTOR CIRCUIT FOR SHORT TO GROUND • Switch the ignition off. • Inspect for continuity between the following terminals: ― Urea injector short cord terminal A and body ground. ― Urea injector short cord terminal B and body ground. • Is there continuity?	Yes	Repair or replace the malfunctioning wiring harness, then go to Step 11.
7		No	Go to the next step.
8	INSPECT UREA INJECTOR CIRCUIT FOR OPEN CIRCUIT • Switch the ignition off. • Inspect for continuity between the following terminals: ― Urea injector short cord terminal A and SCR control unit terminal 74 ― Urea injector short cord terminal B and SCR control unit terminal 91 • Is there continuity?	Yes	Go to the next step.
8		No	Repair or replace the malfunctioning wiring harness, then go to Step 11.
9	INSPECT SCR CONTROL UNIT CONNECTOR FOR POOR CONNECTION • Switch the ignition off. • Disconnect the SCR control unit connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 11.
9		No	Go to the next step.
10	INSPECT UREA INJECTOR CONNECTOR FOR POOR CONNECTION • Switch the ignition off. • Disconnect the urea injector connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to the next step.
10		No	Go to the next step.
11	VERIFY TROUBLESHOOTING OF DTC P2047:11/P2047:12/P2047:13/P2047:14/P2047:15 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the SCR control unit memory using the M-MDS. • Switch the ignition ON for 5 sec. • Retrieve the DTC using the M-MDS. • Is the PENDING CODE for this DTC present?	Yes	Replace the SCR control unit, then go to the next step. (See SCR CONTROL UNIT REMOVAL/INSTALLATION [MZR-CD 2.2].)
11		No	Go to the next step.
12	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZR-CD 2.2].)
