DTC P0882 | TCM B+ low (less than 9 V)
--- | ---
DETECTION CONDITION | • Voltage of less than 9 V detected at TCM terminal 1AD when engine is running. Diagnostic support note: • The MIL illuminates if the TCM detects the above malfunction condition during the first drive cycle. • The AT warning light illuminates if the TCM detects the above malfunction condition during the first drive cycle. • PENDING CODE is not available. • FREEZE FRAME DATA is available. • The DTC is stored in the TCM memory.
POSSIBLE CAUSE | • Melted ROOM 15 A fuse • Poor connection of ROOM 15 A fuse • TCM connector or terminal malfunction • Short to GND in wiring harness between ROOM 15 A fuse and TCM terminal 1AD • Open circuit in wiring harness between ROOM 15 A fuse and TCM terminal 1AD • TCM malfunction

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 the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | INSPECT FUSE • Turn the ignition switch to the LOCK position. • Inspect ROOM 15 A fuse for malfunction. • is it normal? | Yes | Go to the next step.
No | • 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 • 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. Warm-up the engine and transmission. 3. Drive the vehicle in D range and make sure that the gears shift smoothly from 1GR to 6GR. • Is the same DTC present? | Yes | Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
No | Go to the next step.
9 | VERIFY NO DTC HAS BEEN PRESENTED • Perform the “Reading DTCs Procedure”. (See AUTOMATIC TRANSMISSION ON-BOARD DIAGNOSTIC FUNCTION [SJ6A-EL].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [SJ6A-EL].)
No | DTC troubleshooting completed.
