Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related service information availability. • Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. • If the vehicle is not repaired, go to the next step.
1		No	Go to the next step.
2	INSPECT ENG +B 10A FUSE • Switch the ignition to OFF. • Disconnect the negative battery cable. • Inspect the ENG +B 10A fuse for proper installation and failure. • Is it normal?	Yes	Go to the next step.
2		No	• If the fuse is not installed correctly, install it correctly, then go to Step 10. • If fuse has been melted, replace it, then go to Step 8.
3	INSPECT ENG +B 10A FUSE TERMINAL FOR POOR CONNECTION • Switch the ignition to OFF. • Inspect for poor connection (such as damaged, corrosion) • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 8.
3		No	Go to the next step.
4	INSPECT BATTERY POSITIVE TERMINAL FOR POOR CONNECTION • Switch the ignition to OFF. • Inspect for poor connection (such as damaged, corrosion) • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 8.
4		No	Go to the next step.
5	INSPECT BATTERY POSITIVE CIRCUIT FOR SHORT TO GND • Switch the ignition to OFF. • Disconnect the battery positive terminal. • Inspect for continuity between the battery positive terminal (wiring harness-side) and body GND. • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to GND, then go to Step 8.
5		No	Go to the next step.
6	INSPECT TCM CONNECTOR FOR POOR CONNECTION • Switch the ignition to OFF. • Disconnect the TCM 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 8.
6		No	Go to the next step.
7	INSPECT BATTERY POSITIVE CIRCUIT FOR OPEN CIRCUIT • Switch the ignition to OFF. • Disconnect the battery positive terminal. • Inspect for continuity between battery positive terminal (wiring harness-side) and TCM terminal A24 (wiring harness-side). • Is there continuity?	Yes	Go to the next step.
7		No	Repair or replace the wiring harness for a possible open circuit, then go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P0882:00 COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC using the M-MDS. • Perform the following procedure to ensure that the DTC has been resolved: 1. Start the engine. 2. Idle the engine for 120 s or more. • Is the same DTC present?	Yes	Perform the following procedure, then go to next step. 1. Replace the TCM. (See TCM REMOVAL/INSTALLATION [DJVA-EL].) 2. Perform TCM learning. (See TCM LEARNING [DJVA-EL].)
8		No	Go to the next step.
9	VERIFY NO DTC HAS BEEN PRESENTED • Perform the “Reading DTCs Procedure”. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [DJVA-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [DJVA-EL].)
9		No	DTC troubleshooting completed.
