Troubleshooting Test Steps
Values Results
5. Create an Open Circuit at the Solenoid
A. Turn the keyswitch to the OFF position.
B. Disconnect the connector for the suspect solenoid valve.
C. Turn the keyswitch to the ON position. Wait for 10 seconds.
Check for active diagnostic codes on the electronic service
tool.
Short circuit Result: An -6 diagnostic code was active before discon-
necting the valve. An -5 diagnostic code is active with
the valve disconnected.
Repair: Temporarily connect a replacement for the sus-
pect valve to the harness.
Turn the keyswitch to the ON position. Use the electronic
service tool in order to check for active diagnostic codes.
Wait at least 30 seconds in order for the codes to be
displayed.
If the fault is eliminated, reconnect the suspect valve. If
the fault returns, permanently install the replacement
valve. Refer to Disassembly and Assembly for the cor-
rect procedure.
Result: A -6 diagnostic code is still active with the valve
disconnected.
Proceed to Test Step 6.
6. Check the Wiring for a Short Circuit
A. Turn the keyswitch to the OFF position.
B. Disconnect the P2 connector and the connector for the sus-
pect valve.
C. Use a multimeter to check the resistance between the sus-
pect signal terminal on P2 all other terminals on P2. Refer to Il-
lustration 147 .
D. Use a multimeter to check the resistance between the sus-
pect return terminal on P2 and all other terminals on P2. Refer
to Illustration 147 .
E. Reconnect the connectors.
Greater than 100
Ohms
Result: At least one of the resistance measurements is
less than 100 Ohms - The fault is in the engine harness.
Repair: Repair the faulty harness or replace the faulty
harness. Use the electronic service tool to verify that the
repair eliminates the fault.
Result: All resistance measurements are greater than
100 Ohms.

Soot Sensor - Test
This procedure is only applicable to engines that
have a Diesel Particulate Filter (DPF).
Use this procedure to troubleshoot a fault with the
soot sensor. Also, use this procedure if the diagnostic
code in Table 221 is active or easily repeated.
