Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

IMM-213 Communication with control module

Condition




The immobilizer control module checks the communication between engine control module (ECM) and immobilizer in the first two seconds after ignition. Diagnostic trouble code (DTC) IMM-213 is stored if the immobilizer control module contains the wrong data.
The diagnostic trouble code (DTC) is erased when the counter value reaches 254.

Possible source
- EMS interference (strong electrical field) during the communication phase (at start) between immobilizer control module and engine control module (ECM).
- Potential difference of more than 0.4 V between ground terminals for immobilizer control module and engine control module (ECM).

Fault symptom[s]
- The engine starts but stalls directly.
