-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect the IC connector and make sure it seats correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new IC. 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.

K28 CHECK FOR CORRECT TELEMATICS MODULE OPERATION
-
Disconnect the telematics module connector.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect the telematics module connector and make sure it seats correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new telematics module. 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 Tests
Pinpoint Test L: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, Communication Can Be Intermittently
Established
Normal Operation
The High Speed Controller Area Network (HS-CAN) uses an unshielded twisted pair cable. Circuits VDB04 (WH/BU) (HS-CAN +) or VDB05 (WH)
(HS-CAN -) provide the network connection to all HS-CAN modules on the network. In the event that 1 of the 2 network circuits (HS-CAN + or
HS-CAN -) becomes open to a module on the network, unreliable network communication to all modules on the network may result.
In the event that either circuit VDB04 (WH/BU) (HS-CAN +) or VDB05 (WH) (HS-CAN -) becomes open to any module on the network, unreliable
network communication to all modules on the network may result.
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
