AUTOMATIC TRANSMISSION SYSTEM, Diagnostic DTC:P0882

DTC Code	DTC Name
P0882	TCM Power Input Signal Low

DESCRIPTION

TCM detects a reduction in power supply voltage, and depending on status, implements the following fail-safe.

Learning control prohibition (when detection conditions 1 or 2 are met)
Slip control, lock-up control, manual mode, shift paddle operation prohibition, torque up prohibition, and prohibition on shifting to 5th or 6th. If this continues further, power is cut to all solenoids (fixed to 4th).

PROCEDURE

CHECK TCM (POWER SOURCE, GROUND)

Measure the voltage according to the value(s) in the table below.

Standard Voltage

Tester Connection	Condition	Specified Condition
A18-34(IG1) - Body ground	Ignition switch ON	11 to 14 V
A18-35(IG2) - Body ground	Ignition switch ON	11 to 14 V

Measure the resistance according to the value(s) in the table below.

Standard Resistance

Tester Connection	Condition	Specified Condition
A18-3(E02) - Body ground	Always	Below 1 Ω
A18-33(E01) - Body ground	Always	Below 1 Ω
