MULTI-MODE MANUAL TRANSAXLE SYSTEM, Diagnostic DTC:P0562

DTC Code DTC Name
P0562 System Voltage

DESCRIPTION

The battery supplies electricity to the TCM even when the ignition switch is off. This power allows the TCM to store data such as the learning value of actuators, DTC history and freeze frame data. If the battery voltage falls below a minimum level, these memories are cleared and the TCM determines that there is a malfunction in the power supply circuit. If an open or short circuit occurs in the +B circuit while the ignition switch is to ON, the TCM stops operating immediately.

DTC No. DTC Detection Condition Trouble Area

      (to TCM)

      Disconnect the A46 and F68 TCM connectors.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      F68-6 (GND) - Body ground Always Below 1 Ω
      A46-1 (PGND) - Body ground Always Below 1 Ω

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      F68-1 (+B) - F68-6 (GND) Always 11 to 14 V
