Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record FREEZE FRAME 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 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	INSPECT PSP SWITCH CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/ pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace suspected part, then go to Step 8.
3		No	Go to the next step.
4	INSPECT PSP SWITCH CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch off. • Inspect for continuity between PSP switch terminal A (wiring harness-side) and body ground. • Is there continuity?	Yes	Repair or replace suspected part, then go to Step 8.
4		No	Go to the next step.
5	INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/ pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace suspected part, then go to Step 8.
5		No	Go to the next step.
6	INSPECT PSP SWITCH CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between PSP switch terminal A (wiring harness-side) and PCM terminal 2I (wiring harness-side) • Is there continuity?	Yes	Go to the next step.
6		No	Repair or replace suspected part, then go to Step 8.
7	INSPECT FOR CORRECT PCM OPERATION • Disconnect all the PCM connectors. • Visually inspect for: ― Pushed out pins ― Corrosion • Connect all the PCM connectors and verify that they seat correctly. • Retrieve DTCs using the M-MDS. • Is the PENDING CODE for this DTC present?	Yes	Go to the next step.
7		No	The system is correctly. Go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P1650 HAS BEEN COMPLETED • Verify that all disconnected connectors reconnected. • Start the engine. • Clear DTC from PCM memory using the M-MDS. • Perform the “KOEO/KOER Self-Test”. (See KOEO/KOER SELF TEST [MZI-3.7].) • Is same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [MZI-3.7].)
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZI-3.7].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7].)
9		No	Troubleshooting completed.
