C2310

DTC C2310 OPEN OR SHORT CIRCUIT IN BATT

CIRCUIT DESCRIPTION

DTC Detecting Condition:

The auxiliary battery voltage is constantly applied to terminal BATT. The terminal BATT voltage is used to power the transmission control ECU memory. The transmission control ECU outputs this DTC when it detects a malfunction related to terminal BATT.

HINT: When there is an open or short in the BATT circuit, information on the actuator position ("P position" or "non-P position") stored in the ECU is cleared every time the power switch is turned off. Therefore, the ECU works to recognize the position each time the power switch is turned on. As a result, time from when the power switch is turned on until "READY ON" is indicated may become longer than normal.
