Procedure After ECM Replacement

CAUTION:
When ECM is replaced with new one, check the following conditions. Neglecting this check may cause damage to ECM.
- Resistance value of all relays, actuators are as specified respectively.
- APP sensor, TP sensor, A/C refrigerant pressure sensor and EVAP leak check pressure sensor are in good condition and none of power circuits of these sensors is shorted to ground.

NOTE:
- Check and record BCM for DTC before programming the calibration data to ECM because DTC B1691, B1693 and B1695 may be detected in BCM as history DTC after performing the programming to ECM. Then, repair BCM for detected DTC if necessary. However, it is normal even if those DTC are detected in BCM after performing the programming to ECM. Therefore, clear DTC for BCM after performing the programming to ECM.
- When ECM and keyless start control module are replaced with new ones at the same time, perform "Immobilizer Key Registration" instead of "ECM Registration" using SUZUKI scan tool and immobilizer cable. Refer to "SUZUKI SDT Immobilizer Control System Operator's Manual" for the immobilizer registration.

After ECM is replaced with new one, perform the following procedures:
1. Program calibration data to ECM. Refer to "Suzuki ECU Programming System Operator's Manual".
2. Register VIN data to ECM.
3. Perform "ECM Registration".
4. Perform electric throttle control system calibration.
