DIAGNOSIS OF IMMOBILIZER FAULTS
• | Communication between the ECM and the BCM
• | Function of the BCM and the transponder, and
• | Data (stored in the ECM) related to the immobilizer function.
Type | Diasnostic Codes | Immobilizer Related Faults | Fault Types
SMARTRA (2.0β ENGINE) | P1610 | BCM fault | No answer from the BCM Invalid message from BCM to ECM
P1800 | Antenna error
P1803 | Invalid request from ECM or corrupted data
P1801 | Transponder fault | Invalid transponder data Passive mode invalid Programming error
P1805 | EEPROM | Inconsistent data of EEPROM Invalid write operation to EEPROM
ECM fault | No valid data from ECM after 3 attempts by ECM Invalid tester message or unexpected requests by tester
STAND ALONE (2.7δ ENGINE) | 01 | Untaught transponder | Untaught transponder
02 | Transponder communication error | Transponder error due to a wrong code or bad read (wrong transponder in field, or more than one transponder in the field).
03 | ECM communication error | ECM error due to bad Service ID (SID), Bad Message ID (MID) or protocol errors
04 | Immobilizer antenna - open | Open Immobilizer antenna
05 | BCM internal fault or EEPROM | BCM internal fault (smart driver failure) or BCM EEPROM error
06 | ECM not detected | ECM not detected
