Test Step 4. Create a Short Circuit in the
Harness at the Solenoid
A. Turn the keyswitch to the OFF position.
B. Disconnect the P511 connector for the wastegate
regulator.
C. Fabricate a jumper wire between P511:1 and
P511:2 in order to create a short circuit.
D. Turn the keyswitch to the ON position. Access the
"Diagnostics Tests" on the electronic service tool.
Activate the "Turbo Wastegate Solenoid Test".
Wait at least 30 seconds in order for the result to
be displayed.
E. Check for active diagnostic codes on the electronic
service tool.
Expected Result:
The 526-6 diagnostic code is now active.

Test Step 5. Create a Short Circuit at the
ECM
A. Turn the keyswitch to the OFF position.
B. Temporarily remove the wires from P2:17 and
P2:44.
C. Fabricate a jumper wire between P2:17 and P2:44
in order to create a short circuit.
Note: P2/J2 must be connected during the next step.
D. Turn the keyswitch to the ON position. Access
the "Special Tests" under the "Diagnostics" menu
on the electronic service tool. Activate the "Turbo
Wastegate Solenoid Output Test" on the electronic

E. Check for active diagnostic codes on the electronic
service tool.
Expected Result:
The 526-6 diagnostic code is now active.
Results:
•
OK – The 526-6 diagnostic code is now active.

and the solenoid.
Repair: Repair the harness or replace the harness.
STOP.
•
Not OK – There is still an open circuit diagnostic
code.
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
recommends 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.
