Pinpoint Test E: 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).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
IC
PINPOINT TEST E: 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.
-------------------------------------------------
E1 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.
-
Is the resistance between 54 and 66 ohms?
Yes
GO to E2.
No
CONNECT the negative battery cable. GO to E4.
-------------------------------------------------
E2 CHECK THE IC GROUND CIRCUITS FOR AN OPEN
-
Disconnect: IC C220a.
-
Disconnect: IC C220b.
-
Measure the resistance between the IC, harness side and ground as follows:
