Result:A low current diagnostic code (05) is active at this time.Results:
OK - A low current diagnostic code (05) is active at this time. The ECM detected the open at the ECM.Repair: Disconnect the P2 ECM connector. Measure the resistance between the supply wire for the suspect compression brake solenoid and every terminal on ECM connector P1 and ECM connector P2. Measure the resistance between the supply wire for the suspect compression brake solenoid and engine ground. If the wire is shorted, replace the wire.Measure the resistance between the return wire for the suspect compression brake solenoid and every terminal on ECM connector P1 and ECM connector P2. If the wire is shorted, replace the wire.STOP
Not OK - A high current diagnostic code (06) is logged at this time. The ECM did not detect the open.Repair: Replace the ECM. Refer to Troubleshooting, "Replacing the ECM". Verify that the problem is resolved.STOPTest Step 7. Create a Short Circuit at the Compression Brake Solenoid
Turn the keyswitch to the OFF position.
Remove the valve cover.
Reconnect the valve cover connector.
Disconnect the connector on the suspect compression brake solenoid.
Inspect the terminals on the solenoid connector for damage.
Fabricate a jumper wire in order to short the two wires for the suspect solenoid on the solenoid connector. Crimp a pin to each end of the jumper wire.
Make sure that the solenoid connector securely holds the jumper wire. Note: Worn terminals and/or damaged terminals on the solenoid connector could cause an intermittent "Open".
Turn the keyswitch to the ON position.
