Test Step 1. Inspect Electrical Connectors

and Wiring

A. Thoroughly inspect the connectors for the solenoid

valves. Refer to Troubleshooting, “Electrical

Connectors - Inspect” for details.

B. Perform a 45 N (10 lb) pull test on each wire that

is associated with the solenoid valves.

C. Check the screw for the ECM connector for the

correct torque of 6 N·m (53 lb in).

Expected Result:

Results:

• All connectors, pins, and sockets are correctly

connected and the harness is free of corrosion,

abrasion, and pinch points – Proceed to Test Step

2.

• There is a fault in the connectors and/or the

harness.

Repair: 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

connected.

Use the electronic service tool in order to clear all

logged diagnostic codes and then verify that the

repair eliminates the fault.

STOP.

Test Step 2. Check for Diagnostic Codes

A. Turn the keyswitch to the OFF position.

B. Connect the electronic service tool to the

diagnostic connector.

C. Turn the keyswitch to the ON position.

D. Monitor the electronic service tool for active

diagnostic codes and/or logged diagnostic codes.

Results:

• An XXXX-5 diagnostic code is active or recently

logged – Proceed to Test Step 3.

• An XXXX-6 diagnostic code is active or recently

logged – Proceed to Test Step 4.

• No Codes – The fault seems to be resolved.

Repair: For intermittent faults, refer to

Troubleshooting, “Electrical Connectors - Inspect”.

STOP.

Test Step 3. Create a Short Circuit at the

Solenoid Connector

A. Turn the keyswitch to the OFF position.

B. Disconnect the connector for the suspect solenoid.

C. Fabricate a jumper wire. Install the wire between

the two pins on the connector for the suspect

solenoid in order to create a short circuit.

D. Turn the keyswitch to the ON position. Check for

active diagnostic codes on the electronic service

tool.

E. Remove the jumper wire from the connector for

the solenoid valve.

Results:

• Diagnostic code XXXX-6 is active when the jumper

wire is installed – There is a fault in the solenoid.

Repair: Perform the following procedure:

1. Temporarily connect a replacement for the

suspect component to the harness.

2. Turn the keyswitch to the ON position. Use

the electronic service tool in order to check

for active diagnostic codes. Wait at least

3. If the fault is eliminated, reconnect the suspect

component. If the fault returns, permanently

install the replacement component. Refer to

Disassembly and Assembly for the correct

procedure.

STOP.

• An XXXX-5 diagnostic code is still active with the

jumper installed – Proceed to Test Step 5.

Test Step 4. Disconnect the Solenoid in

order to Create an Open Circuit

A. Turn the keyswitch to the OFF position.

B. Disconnect the connector for the suspect solenoid

in order to create an open circuit.

C. Turn the keyswitch to the ON position. Check for

active diagnostic codes on the electronic service

tool. Wait at least 30 seconds in order for the

codes to be displayed.

Results:

• An XXXX-5 diagnostic code is now active – There

is a short in the solenoid.

Repair: Perform the following procedure:

1. Temporarily connect a replacement for the

suspect component to the harness.

2. If the fault is eliminated, reconnect the suspect

component. If the fault returns, permanently

install the replacement component. Refer to

Disassembly and Assembly for the correct

procedure.

STOP.

• Not OK – There is still an XXXX-6 diagnostic code.

Proceed to Test Step 5.

Test Step 5. Bypass the Engine Wiring

Harness

A. Turn the keyswitch to the OFF position.

B. Disconnect the P2 connector and the connector

for the suspect solenoid.

C. Remove the signal wire for the suspect solenoid

from the P1/P2 connector.

D. Remove the signal wire from the connector for the

suspect solenoid.

E. Fabricate a jumper wire that is long enough to

reach from the ECM to the connector for the

suspect solenoid with sockets on both ends.

F. Insert one end of the jumper into the plug for

the signal wire on the P2 connector. Insert the

other end of the jumper into the connector for the

suspect solenoid.

G. Reconnect the P2 connector and the connector

for the solenoid.

H. Turn the keyswitch to the ON position.

I. Use the electronic service tool in order to monitor

the “Active Diagnostic Code” screen. Monitor for

either the open circuit diagnostic code for the

suspect solenoid or the short circuit diagnostic

code for the suspect solenoid.

J. Remove the jumper and reconnect the wires that

were previously removed.

K. Reconnect the P2 connector and the connector

for the suspect solenoid.

Results:

• The diagnostic code disappears when the jumper

is installed – There is a fault in the wiring harness.

Repair: Perform the following repair:

1. Repair the faulty harness or replace the faulty

harness.

2. Use the electronic service tool in order to clear

all logged diagnostic codes and then verify that

the repair eliminates the fault.

STOP.

• The diagnostic code is still present with the jumper

installed

Repair: Perform the following repair:

1. Make sure that the latest flash file for the

application is installed in the ECM. Refer to

Troubleshooting, “Flash Programming”.

2. Contact Perkins Global Technical Support.

Note: This consultation can greatly reduce the repair

time.

3. If Perkins Global Technical Support recommend

the use of a test ECM, install a test ECM. Refer

to Troubleshooting, “Replacing the ECM”.

4. Use the electronic service tool to recheck the

system for active diagnostic codes.

5. If the fault is resolved with the test ECM,

reconnect the suspect ECM.

6. If the fault returns with the suspect ECM,

replace the ECM.

7. Use the electronic service tool in order to clear

all logged diagnostic codes and then verify that

the repair eliminates the fault.
