Troubleshooting Section

Results:

•

OK – The harness connects the ECM to the glow

plug start aid relay and there are no shorts to other

circuits. The ECM or the glow plug start aid relay is

suspect. Proceed to Test Step 4.

•

Not OK – The harness is faulty.

Repair:

If the resistance between P1:57 and

each of the other pins on the P1 connector is less

than 10,000 Ohms then there is a short circuit or

high resistance in the connection to another wire.

Locate the open circuit, the short circuit or high

resistance in the connection in the harness. Repair

the connectors or the harness and/or replace the

connectors or the harness. Ensure that all of the

seals are correctly in place and ensure that the

connectors are correctly coupled. Replace any

fuses that may be open circuit.

Use the electronic service tool in order to clear all

logged diagnostic codes and then verify that the

repair has eliminated the fault.

If the fault still exists, proceed to Test Step 4.

Test Step 4. Bypass the ECM In Order to

Check the Operation of the Glow Plug

Start Aid Relay

Turn the keyswitch to the OFF position.

Disconnect the connection from test point “D” on

the glow plug start aid relay.

Connect a jumper wire between the battery ground

and terminal “D” on the glow plug start aid relay.

Measure the voltage from the battery ground and

terminal “B” on the glow plug start aid relay.

Connect a multimeter between terminal “B” on the

glow plug start aid relay and the battery ground.

Turn the keyswitch to the ON position.

Note:

The engine has not been started at this Test

Step.

Use the electronic service tool in order to operate

the glow plugs.

Measure the voltage from the battery ground and

terminal “B” on the glow plug start aid relay.

Expected Result:

The keyswitch is in the OFF position. The voltage

should be 0 Volts DC.

The keyswitch is in the ON position. The measured

voltage for the 12 Volt systems is a constant 10.5 to

13.5 Volts DC. The measured voltage for the 24 Volt

systems is a constant 21.0 to 27.0 Volts DC.

Results:

•

OK – The glow plug start aid relay is operating

correctly. Reconnect the connection to test point

“D” on the glow plug start aid relay. Proceed to

Test Step 5.

•

Not OK – The glow plug start aid relay is faulty.

Repair:

Replace the glow plug start aid relay.

Use the electronic service tool in order to clear all

logged diagnostic codes and then verify that the

repair eliminates the fault.

If the fault still exists, proceed to Test step 5.

Test Step 5. Check the ECM

Disconnect the P2 connector and disconnect the

P1 connector from the ECM.

Temporarily connect a test ECM. The test ECM

should be programmed with the same values and

parameters as the suspect ECM.

Check the screw for the ECM connector for the

correct torque of 5.0 N·m (44 lb in).

Ensure that all connectors, pins and sockets are

correctly coupled and/or inserted.

Use the electronic service tool in order to perform

a “Glow Plug Override Test”.

Expected Result:

The replacement ECM functions correctly. Performing

the “Glow Plug Override Test” energizes the glow

plugs.

Results:

•

OK – The replacement ECM functions correctly.

Repair:

Install the replacement ECM. Refer to

Troubleshooting, “Replacing the ECM”.

STOP.
