DTC P0613
DTC P0613: TCM Processor
General Description
If the following symptoms occurs, the transmission control module (TCM) stores a DTC.
- The voltage difference of converted voltages from the two analog-to-digital converter is more than the specified voltage.
- RAM/ROM error cannot be corrected by error correcting code.
- Analog-to-digital converter is not functioning properly.
- Communication abnormality between the microcontroller and the watchdog ASIC.
- The ATF temperature sensor value converted by the two analog-to-digital converter does not match.
- Communication abnormality between the microcontroller and the current regulator IC.
- The shift position/mode selected by the driver (input) and the actual shift position/mode (output) does not match.
- The shift position/mode output by the TCM and the A/T gear position indicator does not match.
- Microcontroller failure.

Malfunction Threshold
One of these conditions is met:
- The voltage difference of converted voltages from the two analog-to-digital converter is more than 1.5 V.
- RAM/ROM error cannot be corrected by error correcting code.
- Analog-to-digital converter is not functioning properly.
- Communication abnormality between the microcontroller and the watchdog ASIC.
- The ATF temperature sensor value converted by the two analog-to-digital converter does not match.
- Communication abnormality between the microcontroller and the current regulator IC.
- The shift position/mode selected by the driver (input) and the actual shift position/mode (output) does not match.
- The shift position/mode output by the TCM and the A/T gear position indicator does not match.
- Microcontroller failure.
Possible Cause
The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
- TCM internal failure
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the A/T gear position indicator blinks, the MIL comes on, and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the TCM memory.
Conditions for clearing the DTC
The A/T gear position indicator comes off by turning the vehicle to the OFF (LOCK) mode. The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command.
