Right Cylinder Bank ME-SFI Control Module (N3/12)
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2002 Mercedes-Benz SL600, 2001 Mercedes-Benz SL600, 2000 Mercedes-Benz SL600, 1999 Mercedes-Benz SL600, and 1998 Mercedes-Benz SL600. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
When performing test procedure, make DVOM test connections directly at CAN module or right cylinder bank ME-SFI control module (N3/12) connector.
- CAN Data Bus, Right Cylinder Bank ME-SFI Control Module (N3/12) -
Turn ignition off. Connect DVOM between right cylinder bank ME-SFI control module connector 1 terminals No. 60 and 61 (socket box terminals No. 60 and 61). Resistance should be 75-85 ohms. If resistance is within specification, go to next step. If resistance is not within specification, possible cause is Controller Area Network (CAN) failure. Go to next step.NOTE: Next step refers to Controller Area Network (CAN) module. Vehicle will be equipped with either a Remote Control Locking (RCL) control module (N54) or Drive Authorization System (DAS) control module (N54/1).
- CAN Module Resistance - Turn ignition off. Disconnect Controller Area Network (CAN) module 2-pin connector. Connect DVOM directly to CAN control module terminals. Resistance should be 115-125 ohms. If resistance is within specification, go to next step. If resistance is not within specification, possible cause is CAN module failure. Repair as necessary.
- CAN In Right Cylinder Bank ME-SFI Control Module (N3/12) - Turn ignition off. Connect DVOM between right cylinder bank ME-SFI control module connector 1 terminals No. 60 and 61. Resistance should be 235-245 ohms. If resistance is within specification, test is complete. If resistance is not within specification, possible cause is right cylinder bank ME-SFI control module (N3/12) failure. Repair as necessary.
