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 PUMP SHORT CORD CONNECTOR FOR POOR CONNECTION • Switch the ignition off. • Disconnect the urea pump 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 PUMP • Inspect the urea pump. (See SCR SYSTEM INSPECTION [MZR-CD 2.2].) • Is there any malfunction?	Yes	Replace the urea pump, then go to Step 11. (See UREA PUMP REMOVAL/INSTALLATION [MZR-CD 2.2].)
5		No	Go to the next step.
6	INSPECT UREA PUMP CIRCUIT FOR SHORT TO POWER SUPPLY • Switch the ignition off. • Measure the voltage between the following terminals: ― Urea pump short cord terminal G and body ground. ― Urea pump short cord terminal I and body ground. ― Urea pump short cord terminal J 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 PUMP CIRCUIT FOR SHORT TO GROUND • Switch the ignition off. • Inspect for continuity between the following terminals: ― Urea pump short cord terminal G and body ground. ― Urea pump short cord terminal I and body ground. ― Urea pump short cord terminal J 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 PUMP CIRCUIT FOR OPEN CIRCUIT • Switch the ignition off. • Inspect for continuity between the following terminals: ― Urea pump short cord terminal G and SCR control unit terminal 67. ― Urea pump short cord terminal I and SCR control unit terminal 69. ― Urea pump short cord terminal J and SCR control unit terminal 93. • 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 PUMP 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 P208A:11/P208A:12/P208A:13 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 8 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].)
