Proceed to Test Step 5.

D. From the KOEO Diagnostics menu, select  “Injector”, then select

“Run”  .

Note: During this test, injector solenoids should click in a numerical

sequence. If a series of clicks are not heard for each injector, one or

more injectors are not activating.

E. Record all active diagnostic codes.

5. Injector Disable Test

Cylinders

Result: The test indicates a suspect cylinder.

Note:The injector disable test allows the technician to shut off injec-

tors to determine if a specific cylinder is contributing to engine

performance.

Investigate the cause of the fault on any cylinder that is not

operating. Investigate the cause of the fault on any cylinder

that is operating below normal performance.

A. Connect the electronic service tool to the diagnostic connector.

B. Turn the keyswitch to the ON position.

Note: Possible causes of low compression are shown in

the following list:

· Faulty piston

C. Select “Tests”  from the menu bar. Select “Injector Disable Test”

from the drop-down menu.

· Faulty piston rings

· Worn cylinder bores

· Worn valves

Note: Monitor the engine oil temperature. Do not run the test until

engine oil temperaturereaches 70° C (158° F)

D. Select “Auto Run”  .

· Faulty cylinder head gasket

· Damaged cylinder head

Note: While running the engine, listen for sound variations from cyl-

inder to cylinder.

DTC Description

ECM/IDM communications fault

Comments

543

551

DTC 543 is set by the ECM when the ECM is not communicat-

ing with the IDM

IDM/CMPO signal inactive

The Electronic Control module (ECM) detects the following

conditions:

There is no active Camshaft Position (CMPO) signal between

the ECM and the Injector Driver Module (IDM).

The Crankshaft Position (CKPO) signal is active or the ECM is

reporting that the engine is in  “RUN”  mode.

552

553

IDM incorrect CMPO signal signature

IDM CKPO signal inactive

The ECM detects the following condition:

The CMPO transition occurs at the incorrect CKPO tooth.

This diagnostic code can be caused by electrical noise creating

a miscount on CMPO location.

The ECM detects the following conditions:

There is no active CKPO signal between the ECM and the IDM.

The CMPO signal is active or the ECM is reporting that the en-

gine is in “RUN”   mode.

554

IDM incorrect CKPO signal signature

The ECM detects the following condition:

The CKPO signal has too many or too few transitions per engine

rotation.

This diagnostic code can be caused by electrical noise creating

a miscount on CKPO location.

KENR8774

Symptom Troubleshooting

The ECM/IDM communication link consists of a

series of interdependent signals that include the

CKPO, CMPO, and the CAN 2 datalink.

The CKPO signal is a 0V to 12V signal that

communicates (from ECM to IDM) the position of the

crankshaft. The signal is used by the IDM to

synchronize the injector firing sequence and is

calculated from the signal generated from the CKP

sensor. The ECM generates the CKPO signal by

pulling down (switching to ground) a 12V

communication circuit in the IDM.

The CMPO signal is a 0V to 12V signal that

communicates (from ECM to IDM) the position of the

camshaft. The signal is used by the IDM to

synchronize the injector firing sequence and is

calculated from the signal generated from the CMP

sensor. The ECM generates the CMPO signal by

pulling down (switching to ground) a 12V

communication circuit in the IDM.

CAN 2 datalink is a J1939 high speed private

communication datalink between the ECM, IDM, and

EGR drive module. The ECM receives messages that

include injector coil status, IDM calibration level,

CMPO and CKPO DTCs, injector DTCs, IDM DTCs,

and injector test results from the IDM. The IDM

receives injector diagnostic commands, operation

strategies, modes, and conditions from the ECM.

Note: CAN 2 datalink is used only as communication

between the ECM, IDM, and EGR drive module.

There is no relation to the CAN 1 datalink that is used

for communication with various processors on the

application.

Fault Detection/Management

The ECM continuously monitors the IDM. When the

ECM fails to receive required continuous

communication from the IDM, the ECM will set an

active diagnostic code.
