Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA been recorded on the repair order?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
•  Verify related service repair information availability.
•  Is any related repair information available?
Yes
Perform repair or diagnosis according to the available repair information.

•  If fuse has been melted, go to the next step.
•  If fuse is not installed correctly, install it correctly, then go to Step 8.
4
INSPECT VOLTAGE OF POWER SUPPLY CIRCUIT
•  Inspect for voltage TCM terminal 1AD (wiring harness-side).
•  Is the voltage B+?
Yes
Go to the next step.
No
Go to Step 6.
5
INSPECT TCM CONNECTOR FOR POOR CONNECTION
•  Turn the ignition switch to the LOCK position.
•  Disconnect the TCM connector.
•  Inspect for poor connection at TCM terminals 1AD (such as damaged/pulled-out pins, corrosion).
•  Is terminal normal?
Yes
Go to Step 8.
No
Repair or replace the connector and/or terminal, then go to Step 8.
6
INSPECT POWER SUPPLY CIRCUIT FOR SHORT TO GND
•  Disconnect the positive battery cable.
•  Inspect for continuity between the fuse terminals and body GND.
―   ROOM 15 A fuse terminal and body GND
•  Is there continuity?
Yes
Repair or replace the wiring harness and install new fuse, then go to Step 8.
No
Go to the next step.
7
INSPECT POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT
•  Inspect for continuity between TCM terminal and fuse terminals (wiring harness-side).
―  Terminal 1AD and ROOM 15 A fuse
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the harness, then go to the next step.
8
VERIFY TROUBLESHOOTING OF DTC P0882 COMPLETED
