-
Are the resistances less than 5 ohms?
Yes
CONNECT the negative battery cable. GO to D4.
No
REPAIR the circuit. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
D4 CHECK FOR CORRECT SJB OPERATION
-
Disconnect all the SJB connectors.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect all the SJB connectors and make sure they seat correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new SJB. 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. CLEAR the DTCs. REPEAT the
network test with the scan tool.

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). Circuits VDB04 (WH/BU)
(HS-CAN +) and VDB05 (WH) (HS-CAN -) provide the network connection to the IC. Voltage is supplied by circuits SBP33 (RD), CBP09 (VT/GY)
and CBP10 (YE/OG). Ground is supplied by circuits GD161 (BK/YE) and GD174 (BK/WH).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
IC
