GENERAL DESCRIPTION
BZ:DTC P0604 INTERNAL CONTROL MODULE RANDOM ACCESS MEMORY
(RAM) ERROR
1. OUTLINE OF DIAGNOSIS
Detect the malfunction of microcomputer (RAM).
When there is a problem in the main CPU normal RAM, or the sub CPU normal RAM, judge as NG. Judge
as OK when both are operating properly.
If it is possible to write data to the whole area of RAM in the initial routine, and is possible to read the same
data, it is judged as OK, and if not, NG.
2. ENABLE CONDITION
Diagnosis with the initial routine.
3. GENERAL DRIVING CYCLE
Perform the diagnosis as soon as the ignition switch is turned to ON.
4. DIAGNOSTIC METHOD
