id050211804300

DTC P0983

Shift solenoid D circuit malfunction (short to power)

DETECTION

CONDITION

• Short circuit in shift solenoid D signal system (The solenoid circuit current value input to the TCM is

continuously more than 1,333 mA for 100 ms or more).

Diagnostic support note:

• This is a continuous monitor (CCM).

• The MIL illuminates 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 illuminates.

• The DTC is stored in the TCM memory.

POSSIBLE

CAUSE

• Short to power in wiring harness between shift solenoid D terminal B and TCM terminal B17

• Short to power in wiring harness between shift solenoid D terminal A and TCM terminal B18

• Shift solenoid D malfunction

• Damaged connector between line pressure control solenoid and TCM

• TCM malfunction
