Troubleshooting Test Step Value Result
1. Check for Codes
A. Establish communication between Cat® Electronic Technician (ET) and the Electronic Control Module (ECM). Refer to Troubleshooting, Electronic Service Tools if necessary.
B. Turn the keyswitch to ON.
C. Look for an active or logged code.
Codes
Result: No codes are present.
Proceed to Test Step 7.
Result: There are codes present.
Proceed to Test Step 2.
2. Check the Resistance of the DCU Resistor
A. Turn the keyswitch to OFF.
B. Disconnect the 86-pin connector from the DCU that is logging the code.
C. Measure the resistance between pin-38 and pin-39 on the DCU that is logging the code.
- For Aftertreatment #1 DCU #1 the resistance should be 178Ω 10Ω
- For Aftertreatment #2 DCU #2 the resistance should be 604Ω 10Ω
- For Aftertreatment #2 DCU #1 the resistance should be 1540Ω 10Ω
- For Aftertreatment #2 DCU #2 the resistance should be 5230Ω 10Ω
Note: The 398-5063 Probe must be used to prevent damage to the DCU connector.
