Diagnostic Trouble Codes
CDL Code Code Description Comments
2232-5 Engine Retarder Solenoid : Current Below Normal This code indicates there is a problem with the engine retarder solenoid and/or electrical circuit on the ECM.
2232-6 Engine Retarder Solenoid : Current Above Normal This code indicates there is a problem with the pilot fuel solenoid and/or electrical circuit on the CEM.
Follow the troubleshooting procedure in order to identify the root cause of the problem. Note: Refer to Troubleshooting, "Component Location" in this manual for the proper location of the components listed in this procedure.Electrical Checkouts on the Caterpillar Electronic Technician (ET)

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Establish communication between Cat ET and the 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.
Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
C. Look for these active codes or logged codes:
• -5
• -6
Codes
Result: A -5 diagnostic code is active.
Proceed to Test Step 2.
Result: A -6 diagnostic code is active.
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. Clear the -5 code.
E. 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.
STOP
Result: A -6 code is activated during the electrical checkout. The ECM detected the jumper wire. There is a problem with the solenoid. Clear the -6 code by cycling the keyswitch to the Off position.
Repair: Replace the solenoid.
STOP
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 the Off position.
C. Perform the appropriate electrical checkout. Refer to Table 2.
Short Circuit
Result: A -6 code became active during the electrical checkout. he 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.
STOP
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.
