Troubleshooting Test Steps
Values Results
5. Create an Open Circuit at the Relay
A. Turn the keyswitch to the OFF position.
B. Disconnect the aftertreatment power relay.
C. Use the electronic service tool to check for active diagnos-
tic codes. Wait at least 30 seconds for activation of the diag-
nostic codes.
Diagnostic codes Result: A 5965-5 or 3838-5 diagnostic code is active with
the relay disconnected.
Repair: Install a replacement aftertreatment power relay.
Use the electronic service tool to clear all logged diagnostic
codes and verify that the repair eliminates the fault.
Result: The 5965-6 or 3838-6 diagnostic code is still active
with the relay disconnected.
Proceed to Test Step 6.
6. Check the Wiring Between the Relay and the ECM for a
Short Circuit
A. Disconnect the P1 connector.
B. Inspect the P1 connector. Refer to Troubleshooting, “Elec-
trical Connectors - Inspect” for details.
C. Measure the resistance between P1:5 and all other termi-
nals on the P1 connector.
D. Measure the resistance between P1:15 and all other termi-
nals on the P1 connector.
Greater than 1.0 k
Ohm
Result: At least one of the resistance measurements is less
than 1.0 k Ohm. There is a short in the wiring between the
relay and the ECM.
Repair: Repair the faulty wiring or replace the faulty wiring.
Use the electronic service tool to clear all logged diagnostic
codes and verify that the repair eliminates the fault.
Result: All resistance measurements are greater than 1.0 k
Ohm.

Sensor Calibration Required -
Test
The Electronic Control Module (ECM) performs
calibrations of pressure sensors automatically. Use
this procedure if the diagnostic code in Table 206 is
active or easily repeated.
