Use the electronic service tool in order to clear all
logged diagnostic codes and then verify that the
repair eliminated the fault.
STOP.
Test Step 5. Check the Voltage at the ECM
A.
Disconnect the P1 connector.
B.
Temporarily disconnect the wire from the P1
connector that supplies the suspect lamp.
C.
Fabricate the jumper wire with a suitable pin for
the P1 connector.
D.
Install one end of the jumper wire into the P1
connector that supplies the suspect lamp. Connect
a test lamp between the and the jumper
wire.
E.
Reinstall the P1 connector to the ECM.
F.
Turn the keyswitch to the ON position. Use the
electronic service tool to select the override
function in order to switch individual lamps ON
and OFF.
Note:
The “Override” function is contained in the
“Diagnostics” menu of the electronic service tool.
Expected Result:
The lamp should illuminate.
Results:
•
OK – The ECM is operating correctly.
There is a fault in the wiring or the lamp.
Repair the wiring or the lamp, as required.
Verify that the repair eliminates the fault.
STOP.
•
Not OK – There is a suspected fault in the ECM.
Repair:
Perform the following procedure:
1.
Temporarily connect a test ECM.
2.
Program the ECM with the same parameters
as the suspect ECM.
3.
Check the operation of the diagnostic lamp
when the test ECM is installed.
4.
If the fault is resolved with the test ECM, then
reconnect the suspect ECM.
5.
If the fault returns with the suspect ECM, then
replace the suspect ECM.
STOP.

Injector Data Incorrect - Test
System Operation Description:
Use this procedure under the following situation:
Use this procedure for any of the following diagnostic
codes:
•
0001-02 Cylinder #1 Injector erratic, intermittent,
or incorrect
•
0002-02 Cylinder #2 Injector erratic, intermittent,
or incorrect
•
0003-02 Cylinder #3 Injector erratic, intermittent,
or incorrect
•
0004-02 Cylinder #4 Injector erratic, intermittent,
or incorrect
•
0005-02 Cylinder #5 Injector erratic, intermittent,
or incorrect
•
0006-02 Cylinder #6 Injector erratic, intermittent,
or incorrect
The following background information is related
to this procedure:
The engine has electronic unit injectors that are
electronically controlled by the Electronic Control
Module (ECM). The ECM sends a 70 Volt pulse
to each injector solenoid. The pulse is sent at the
correct time and for the correct duration for a given
engine load and engine speed. Use this procedure
to identify the cause of the diagnostic code. Use this
procedure to repair the system.
If an injector is replaced, then the correct injector
trim
fi
les must be programmed into the ECM. The
injector trim
fi
les allow each individual injector to be
fi
ne tuned for optimum performance. The ECM will
generate the following diagnostic code if the injector
trim
fi
les are not programmed:
•
0268-02 Programmed Parameter Fault erratic,
intermittent, or incorrect
