-
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. REFER to Air Bag Systems. 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.

Pinpoint Test G: The Instrument Cluster (IC) Does Not Respond To The Scan Tool
Refer to Wiring Diagram Set 14, Module Communications Network for schematic and connector information. See: Diagrams/Electrical
Diagrams/Diagrams By Number
Refer to Wiring Diagram Set 60, Instrument Cluster for schematic and connector information. See: Diagrams/Electrical Diagrams/Diagrams By Number
Normal Operation
The Instrument Cluster (IC) 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 HS-CAN connection to the IC and circuits VDB06 (GY/OG) (MS-CAN +) and VDB07
(VT/OG) (MS-CAN -) provide the MS-CAN connection to the IC. Voltage for the IC is provided by circuits CDC34 (WH/OG) and SBP24 (VT/RD).
Circuit GD145 (BK/BU) provides ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
IC
PINPOINT TEST G: THE IC DOES NOT RESPOND TO THE SCAN TOOL
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
-------------------------------------------------
G1 CHECK THE HS-CAN TERMINATION RESISTANCE
-
Ignition OFF.
-
Disconnect: Negative Battery Cable.
-
Disconnect the scan tool cable from the Data Link Connector (DLC).
-
Measure the resistance between the DLC C251-6, circuit VDB04 (WH/BU), harness side and the DLC C251-14, circuit VDB05 (WH), harness
side.
