D.
Remove the fuses from the wire of the
bypass harness and connect the and the
Battery- wires directly to the battery terminals.
Note:
This bypass directly connects the circuit for the
keyswitch to the ECM. The ECM will remain powered
until the connection to the unswitched line
is disconnected. Remove the fuses from the in-line
fuse holder to power down the ECM. Do not connect
the bypass to the battery terminals or do not remove
the bypass from the battery terminals without
fi
rst
removing the in-line fuses.
E.
Connect the electronic service tool to the
diagnostic connector of the bypass harness and
verify that communication can be established.
Note:
Remove the bypass harness and restore all
wiring to the original condition after testing.
Expected Result:
Installing the bypass eliminates the fault.
Note:
The status of the “Ignition Keyswitch” will
always indicate ON while the bypass harness is
installed.
Results:
•
OK – The symptom disappears when the bypass
harness is installed. The symptom returns when
the bypass harness is removed. The fault is in the
wiring for the application that supplies power to
the ECM. Check for aftermarket engine protection
switches that interrupt power. Send the application
to the OEM dealer to repair. STOP.
•
Not OK – The symptom is still present when the
bypass harness is installed.
Repair:
Connect the bypass to another battery and
verify if the fault is resolved. If the fault is resolved,
the fault is with the batteries on the application.
If the fault still exists, temporarily connect a
test ECM. Remove all jumpers and replace
all connectors. Recheck the system for active
diagnostic codes and repeat the Test Step. If the
fault is resolved with the test ECM, reconnect the
suspect ECM. If the fault returns with the suspect
ECM, replace the ECM.
Use the electronic service tool in order to clear all
logged diagnostic codes and then verify that the
repair eliminates the fault.
STOP.
