DTC P0882:00

TCM power supply voltage low

DETECTION CONDITION

• Under the following conditions, the TCM power supply voltage is 8—10.5 V or less (varies with ATF temperature):

• 5 s or more has elapsed or battery voltage exceeds 11 V or more for 0.2 s since engine speed increases −200 rpm or more of target idle speed.

• Selector lever position is D or R position.

Diagnostic support note

• The check engine light illuminates if the TCM detects the above malfunction condition during the first drive cycle.

• The automatic transaxle warning light does not illuminate.

• PENDING CODE is available.

• FREEZE FRAME DATA is available.

• DTC is stored in the TCM memory.

FAIL-SAFE FUNCTION

• Set to emergency mode.

• Inhibits learning control.

• Inhibits manual mode.

• Inhibits neutral idle control.

• Inhibits AAS.

POSSIBLE CAUSE

• PCM DTC is stored.

• Battery malfunction

• Generator malfunction

• TCM connector or terminals malfunction

• TCM power supply circuit malfunction

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

• AT 15 A fuse malfunction

• Open circuit in wiring harness between battery positive terminal and TCM terminal A

INSPECTION

ACTION

1

• Has the freeze frame data/snapshot data been recorded on the repair order?

Yes

Go to the next step.

No

Record the freeze frame data/snapshot data on the repair order, then go to the next step.

2

• Verify related Service Bulletins and/or on-line 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

• Perform the PCM DTC inspection using the M-MDS.

  (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.5].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [SKYACTIV-G 2.5].)

No

Go to the next step.

4

• Inspect the battery.

  (See BATTERY INSPECTION [SKYACTIV-G 2.5].)

• Is there any malfunction?

Yes

Recharge or replace the battery, then go to Step 8.

(See BATTERY RECHARGING [SKYACTIV-G 2.5].)

(See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)

No

Go to the next step.

5

• Inspect the generator.

  (See GENERATOR INSPECTION [SKYACTIV-G 2.5 (WITHOUT i-ELOOP)].)

  (See GENERATOR INSPECTION [i-ELOOP].)

• Is there any malfunction?

Yes

Replace the generator, then go to Step 8.

(See GENERATOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5 (WITHOUT i-ELOOP)].)

(See GENERATOR REMOVAL/INSTALLATION [i-ELOOP].)

No

Go to the next step.

6

• Switch the ignition off.

• Disconnect the TCM connector.

• Visually inspect the TCM connector and terminals.

• Is there any malfunction?

Yes

Repair or replace the connector and/or terminals, then go to Step 8.

No

Go to the next step.

7

• Always reconnect all disconnected connectors.

• Access the PID VPWR using the M-MDS.

  (See ON-BOARD DIAGNOSTIC SYSTEM PID/DATA MONITOR INSPECTION [FW6A-EL].)

• Is the PID value B+?

Yes

Go to the next step.

No

Inspect the AT 15 A fuse.

• If the fuse is burnt out:

• Refer to the wiring diagram and verify whether or not there is a common connector between AT 15 A fuse and TCM terminal A.

If there is a common connector:

• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.

• Repair or replace the malfunctioning part.

If there is no common connector:

• Repair or replace the wiring harness which has a short to ground.

• Replace the fuse.

• If the fuse is deteriorated:

• Replace the malfunctioning fuse.

• If the fuse is normal:

• Refer to the wiring diagram and verify whether or not there is a common connector between battery positive terminal and TCM terminal A.

If there is a common connector:

• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.

• Repair or replace the malfunctioning part.

If there is no common connector:

• Repair or replace the wiring harness which has an open circuit.

Go to the next step.

8

• Always reconnect all disconnected connectors.

• Clear the DTC using the M-MDS.

  (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FW6A-EL].)

• Perform the following procedure to ensure that the DTC has been resolved:

• Drive the vehicle for 5 s or more under the following condition:

• Selector lever position: D or R position

• Perform the DTC inspection using the M-MDS.

  (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FW6A-EL].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [FW6A-EL].)

No

DTC troubleshooting completed.
