MKS AWD V6-3.7L (2009)
-
Are the resistances less than 5 ohms?
Yes
GO to E4.
No
REPAIR the circuit. REACTIVATE the SRS. REFER to Air Bag Systems. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
E4 CHECK FOR CORRECT OCSM OPERATION
-
Disconnect the OCSM connector.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect the OCSM connector and make sure it seats correctly.
-
Verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new OCSM. REACTIVATE the SRS. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. REACTIVATE the SRS. REFER to
Air Bag Systems. CLEAR the DTCs. REPEAT the network test with the scan tool.

Normal Operation
The Headlamp Control Module (HCM) communicates with the scan tool through the High Speed Controller Area Network (HS-CAN). Circuits VDB04
(WH/BU) (HS-CAN +) and VDB05 (WH) (HS-CAN -) provide the network connection to the HCM. Voltage to the HCM is supplied by circuit CBP33
(WH/BN). Ground is supplied by circuit GD120 (BK/GN).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
HCM
