EEPROM Memory Fault

EEPROM memory fault

Checking the control module








- Ignition off.
- Wait approximately 150 seconds.
- Start the engine
The EEPROM in the control module stores diagnostic trouble codes (DTC), diagnostic trouble code (DTC) counters and frozen values. If the memory circuit is malfunctioning, no information can be read from it. Simulate a fault to check the condition of the memory. This stores a diagnostic trouble code (DTC). The memory can then be checked by reading off the diagnostic trouble code (DTC) information.
- Disconnect the 6-pin transmission connector. Solenoid-related diagnostic trouble codes (DTCs) will be stored.
- Wait approximately 30 seconds.

Checking the control module, continued




- Ignition off.
- Wait approximately 150 seconds.
- Ignition on.
Read off diagnostic trouble codes (DTCs).





Has a diagnostic trouble code (DTC) been stored?

Yes - Fault-tracing information

No - Replacing the component

-------------------------------------------------

Fault-tracing information
The memory circuit is functioning.

Replacing the component




- Ignition off.
Try a new control module according to Replacing the transmission control module (TCM) .
