DTC P0601

- Control Module Read Only Memory (ROM)

DTC P0602

- Control Module Not Programmed

DTC P0603

- Control Module Long Term Memory Reset

DTC P0604

- Control Module Random Access Memory (RAM)

DTC P062F

- Control Module Long Term Memory Performance

Circuit/System Description

This is an internal fault detection of the control solenoid valve assembly. This fault is carried out inside the control solenoid valve assembly and no

external circuits are involved.

Conditions for Running the DTC

* DTCs P0601, P0602, P0603, P0604, or P062F are not set.

* Ignition voltage is 8.6 volts or greater.

Conditions for Setting the DTC

P0601

The read only memory (ROM) test has failed 5 or more times.

P0602

The transmission control module (TCM) has not been programmed.

P0603

The TCM has detected a memory checksum error.

P0604

The TCM random access memory (RAM) test has failed 5 or more times.

P062F

The TCM has detected non-volatile memory is incorrect during power-down.

Action Taken When the DTC Sets

* DTCs P0601, P0602, P0603, P0604, and P062F are Type A DTCs.

* The TCM shifts to a default gear, shuts down, and turns OFF.

Conditions for Clearing the DTC

DTCs P0601, P0602, P0603, P0604, and P062F are Type A DTCs.

DTC P062F

- Control Module Long Term Memory Performance

Circuit/System Description

This is an internal fault detection of the power inverter module (PIM). This fault is handled inside the PIM and no external circuits are involved.

Conditions for Running the DTC

* The control module runs the program to detect an internal fault when the key is ON.

* Ignition voltage is 7V or greater.

Conditions for Setting the DTC

The control module has detected an internal malfunction.

Action Taken When the DTC Sets

* DTCs P0601, P0602, P0603, P0604, P0606 and P062F are Type A DTCs.

* The hybrid powertrain control module (HPCM) commands the battery energy control module (BECM) to open the high voltage contactor

relays.

Conditions for Clearing the DTC

DTCs P0601, P0602, P0603, P0604, P0606 and P062F are Type A DTCs.

瀚慞erform HPCM P0562 diagnosis if set.

2. Clear the DTC information.

3. Ignition OFF for 1 minute.

4. Ignition ON.

5. Retest for DTCs P0601, P0602, P0603, P0604, P0606 and P062F.
