This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
PINPOINT TEST S: INTERMITTENT NO HS-CAN COMMUNICATION, COMMUNICATION CAN BE INTERMITTENTLY
ESTABLISHED
NOTE: Various modules set network DTCs during this test procedure. Clear the DTCs from all modules after the diagnostic procedure is complete.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
-------------------------------------------------
S1 CHECK THE DLC PINS FOR DAMAGE
-
Ignition OFF.
-
Disconnect the scan tool cable from the Data Link Connector (DLC).
-
Inspect DLC pins 6 and 14 for damage.
-
Are DLC pins 6 and 14 OK?
Yes
GO to S2.
No
REPAIR the DLC as necessary. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
S2 CHECK THE HS-CAN TERMINATION RESISTANCE
-
Disconnect: Negative Battery Cable .
-
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
