P0882

DTC P0882 TCM POWER INPUT SIGNAL LOW

COMPONENT LOCATION:

GENERAL DESCRIPTION
TCU check the Battery voltage, in order to maintain optimum condition of each sensors and solenoid-valve.

DTC DESCRIPTION
TCU set this code, when input lower voltage than specified value.

DTC DETECTING CONDITION:

SCHEMATIC DIAGRAM:

MONITOR SCANTOOL DATA
1. Connect Scantool to data link connector (DLC).
2. Engine "ON".
3. Monitor the "A/T RELAY VOLTAGE" parameter on the scan tool.





4. Is "A/T RELAY VOLT"within specification?
YES
- Go to "IG Power inspection" procedure.
NO
- Repair "Fuse and Battery and relation part" as necessary and Go to "Verification of Vehicle Repair" procedure.

1. IG POWER INSPECTION
1. Engine "OFF" IG KEY "ON".
2. Remove the TCU.
3. Measure the voltage between terminal of "IG power" and chassis ground.
Specification: Battery voltage (Approximately 10-14V)
4. Is "VOLTAGE" within specification?
YES
- Go to "IG ground inspection" procedure.
NO
- Repair "Fuse and Battery and relation part" as necessary and Go to "Verification of Vehicle Repair" procedure.

IG GROUND INSPECTION
1. Engine "OFF" IG KEY "ON".
2. Remove the TCU.
3. Perform the continuity test between "IG power" terminal and chassis ground.
Specification: Not continuity
4. Is resistance within specifications?
YES
- Go to "Battery power inspection" procedure.
NO
- Repair "Fuse and Battery and relation part" as necessary and Go to "Verification of Vehicle Repair" procedure.

2. BATTERY POWER INSPECTION
1. Engine "OFF" IG KEY "ON".
2. Remove the TCU.
3. Measure the voltage between Battery power (B+) terminal of wiring harness and ground terminal. specification:
Battery voltage (Approximately 10-14V)
4. Is "VOLTAGE" within specification?
YES
- Go to "Battery ground inspection1" procedure.
NO
- Repair "Fuse and Battery and relation part" as necessary and Go to "Verification of Vehicle Repair" procedure.

BATTERY GROUND INSPECTION 1
1. Engine "OFF" IG KEY "ON".
2. Remove the TCU.
3. Measure the voltage between Battery power (B+) terminal of Wiring harness and chassis ground.
Specification: Battery voltage (Approximately 10-14V)
4. Is "VOLTAGE" within specification?
YES
- Go to "Battery ground inspection 2" procedure.
NO
- Repair "Fuse and Battery and relation part" as necessary and Go to "Verification of Vehicle Repair" procedure.

BATTERY GROUND INSPECTION 2
1. Engine "OFF" IG KEY "ON".
2. Remove the TCU.
3. Perform the continuity test between "Ground" terminal of wiring harness side and chassis ground.
Specification: Continuity
4. Is resistance within specifications?
YES
- Fault is intermittent caused by poor contact in the sensor's and/or TCM (PCM)'s connector or was repaired and TCM (PCM) memory was not cleared. Thoroughly check correctors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.
NO
- Repair "Fuse and Battery and relation part" as necessary and Go to "Verification of Vehicle Repair" procedure.

VERIFICATION OF VEHICLE REPAIR
After a repair, it is essential to verify that the fault has been corrected.
1. Connect Scantool and select "Diagnostic Trouble Codes (DTCs)" mode.
2. Using a Scantool, Clear DTC.
3. Operate the vehicle within DTC Enable conditions in General information.
4. Are any DTCs present?
YES
- Go to the applicable troubleshooting procedure.
NO
- System performing to specification at this time.
