* 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.

Circuit/System Verification
1. Ignition OFF for one minute.
Caution: Before programming a control module, the following must be observed, or control module damage may occur:
* The scan tool and the terminal must have the latest software.
* The vehicle battery must be fully charged. The battery voltage should be between 12-14 volts.
* The scan tool and the terminal cable connections must be secure.
* A battery charger must NOT be connected to the battery when programming a control module.
2. Ignition ON, with a scan tool verify that DTC P0602 is not set.
瀚慖f DTC P0602 is set, program the transmission control module. Refer to Service Programming System (SPS) (See: Testing and
Inspection/Programming and Relearning/Service Programming System (SPS)) and Control Solenoid Valve and Transmission Control
