id0502j6802800

DTC P0882

TCM B+ low

DETECTION CONDITION

•  Voltage of less than 9 V detected at TCM terminals A1 and A11 when engine is running.

Diagnostic support note:

•  This is a continuous monitor (CCM).

•  The MIL does not illuminate if the TCM detects the above malfunction condition during the first drive cycle.

•  A PENDING CODE is not available.

•  FREEZE FRAME DATA is available.

•  The AT warning light not illuminates.

•  The DTC is stored in the TCM memory.

POSSIBLE CAUSE

•  Melted METER 10 A fuse

•  Melted ENGINE 20 A fuse

•  Open circuit in wiring harness between ENGINE 20 A fuse and TCM terminal A1

•  Open circuit in wiring harness between METER IG 15 A fuse and TCM terminal A11

•  Open circuit in wiring harness between TCM terminal A9 and body ground

•  Short to ground in wiring harness between ENGINE 20 A fuse and TCM terminal A1

•  Short to ground in wiring harness between ROOM 15 A fuse and TCM terminal A11

•  Poor connection of TCM connector

•  Poor connection of BCM connector

•  TCM malfunction

•  BCM malfunction

POSSIBLE CAUSE	• Melted METER 10 A fuse • Melted ENGINE 20 A fuse • Open circuit in wiring harness between ENGINE 20 A fuse and TCM terminal A1 • Open circuit in wiring harness between METER IG 15 A fuse and TCM terminal A11 • Open circuit in wiring harness between TCM terminal A9 and body ground • Short to ground in wiring harness between ENGINE 20 A fuse and TCM terminal A1 • Short to ground in wiring harness between ROOM 15 A fuse and TCM terminal A11 • Poor connection of TCM connector • Poor connection of BCM connector • TCM malfunction • BCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		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 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.
2		No	Go to the next step.
3	INSPECT FUSE • Turn the ignition switch to the LOCK position. • Inspect METER 10 A fuse and ENGINE 20 A fuse for malfunction. • Is it normal?	Yes	Go to the next step.
3		No	• If fuse has been melted, go to the next step. • If fuse is not installed correctly, install it correctly, then go to Step 10.
4	INSPECT VOLTAGE OF POWER SUPPLY CIRCUIT • Turn the ignition switch to the ON position (engine off). • Inspect for voltage TCM connector terminal A1 and A11 (wiring harness-side). • Is the voltage B+?	Yes	Go to go to Step 8.
4		No	Go to the next step.
5	INSPECT POWER SUPPLY CIRCUIT FOR SHORT TO GROUND • Disconnect the positive battery cable. • Inspect for continuity between the fuse terminals and body ground. ― METER 10 A fuse terminal and body ground ― ENGINE 20 A fuse terminal and body ground • Is there continuity?	Yes	Repair or replace the wiring harness and install new fuse, then go to Step 10.
5		No	Go to the next step.
6	INSPECT POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between TCM connector terminals and fuse terminals (wiring harness-side). ― TCM terminal A1 and BCM terminal 2F ― BCM terminal 4A and ENGINE 20 A fuse ― TCM terminal A11 and METER 10 A fuse • Is there continuity?	Yes	Go to Step 9.
6		No	Repair or replace the harness and BCM, then go to Step 10.
7	INSPECT BCM CONNECTOR FOR POOR CONNECTION • Disconnect the BCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are terminals normal?	Yes	Go to the next step.
7		No	Replace the couple component, then go to Step 10.
8	INSPECT TCM CONNECTOR FOR POOR CONNECTION • Disconnect the TCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are terminals normal?	Yes	Go to the next step.
8		No	Replace the couple component, then go to Step 10.
9	INSPECT GROUND CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between TCM connector terminal A9 (wiring harness-side) and body ground. • Is there continuity?	Yes	Go to the next step.
9		No	Repair or replace the harness, then go to the next step.
10	VERIFY TROUBLESHOOTING OF DTC P0882 COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC from the memory using the M-MDS. • Start the engine and warm it up completely. • Is the same DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [AW6AX-EL].)
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE [AW6AX-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [AW6AX-EL].)
11		No	DTC troubleshooting completed.
