Component Electrical Checkout
Engine retarder solenoid Engine Retarder Solenoid Override - initiate an engine retarder solenoid override through Cat ET to activate the engine retarder solenoid. Review active diagnostic codes to determine what code is present.
Engine Intake Valve Actuation System Oil Pressure Control Valve Start the engine. Use the "Intake Valve Actuation System Test" in diagnostic tests in Cat ET to activate the Engine Intake Valve Actuation System Oil Pressure Control Valve. Once the test is complete, review the active diagnostic codes to determine the code that is present.
Exhaust balance valve solenoid Use the "Engine exhaust manifold bank #1 flow balance valve solenoid override" in the override parameters section in Cat ET to activate the exhaust balance valve solenoid. Review active diagnostic codes to determine what code is present.
Engine Starter Motor Relay Attempt to start the engine. Once the ECM attempts to energize the relay, the code will become active.
Refer to the machine-specific schematic for the "Engine Starter Motor Relay" wiring circuit.

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Establish communication between Cat® Electronic Technician (Cat ET) Service Tool and the Electronic Control Module (ECM) . Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Wait at least 30 seconds in order for the diagnostic codes to become active. Look for an active -5 code or for a logged -6 code.
Codes
Result: There is an active or there is a logged -5 code.
Proceed to Test Step 2.
Result: There is an active or there is a logged -6 code.
Proceed to Test Step 3.
2. Check the Wiring for an Open Circuit
A. Verify that the harness connector is free of debris, free of corrosion, and securely connected.
B. Disconnect the solenoid from the engine harness.
C. Connect a jumper wire between the terminals of the harness connector for the suspect coil. The coil is replaced with a short circuit.
D. Perform the appropriate electrical checkout. Refer to Table 2.
Open Circuit
Result: A -5 code became active during the electrical checkout. The ECM did not detect the jumper wire. There is an open circuit in the wiring between the coil and the ECM connector. There may be a problem with a connector.
Repair: Repair the appropriate harness wiring or replace the appropriate harness. Verify that the problem is resolved.
Result: A -6 code is activated during the electrical checkout. The ECM detected the jumper wire. There is a problem with the solenoid.
Repair: Replace the solenoid. Clear the -6 code by cycling the keyswitch to OFF.
3. Check the Wiring for a Short Circuit
A. Disconnect the solenoid from the engine harness.
B. Clear the -6 code by cycling the keyswitch to OFF.
C. Perform the appropriate electrical checkout. Refer to Table 2.
Short Circuit
Result: A -6 code became active during the electrical checkout. The ECM did not detect the open circuit. There is a short circuit in the wiring between the coil and the ECM connector. There may be a problem with a connector.
Repair: Repair the appropriate harness wiring or replace the appropriate harness.
Result: A -5 code became active during the electrical checkout. The ECM detected the open circuit. The wiring is OK. The coil has a short circuit.
Repair: Replace the solenoid. Verify that the problem is resolved.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
