Transit Connect L4-2.0L (2010)
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CONNECT all modules. CLEAR
the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
M22 CHECK FOR CORRECT IC OPERATION
-
Disconnect all the IC connectors.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect all the IC 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 IC. REFER to Instrument Panel, Gauges and Warning Indicators. CONNECT all modules. 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. CONNECT all modules. CLEAR
the DTCs. REPEAT the network test with the scan tool.

Pinpoint Test N: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, One Or More Modules Are Not
Responding During Network Test
Refer to Wiring Diagram Set 14, Module Communications Network for schematic and connector information. See: Diagrams/Electrical
Diagrams/Diagrams By Number
Normal Operation
The High Speed Controller Area Network (HS-CAN) uses an unshielded twisted pair cable.
In the event that either the HS-CAN (+) or HS-CAN (-) circuit becomes open to a 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
-
Data Link Connector (DLC)
PINPOINT TEST N: INTERMITTENT NO HS-CAN COMMUNICATION, ONE OR MORE MODULES ARE NOT RESPONDING
DURING NETWORK TEST
NOTE: Various modules set network DTCs during this test procedure. Clear DTCs from all modules after the diagnostic procedure is completed.
