You Do Not Have To Use The Entire Troubleshooting Section To Troubleshoot A Problem. Do The Steps In Sequence:
Step 1. Gather Information:Ask the driver specific questions about the operation of the engine and/or vehicle, and the customer's complaint.Step 2. Check For A Diagnostic Code:The 3176 Engine electronics has a diagnostic capability that will detect a fault (active or intermittent) and signal the operator by turning on the "check engine" light in the cab. The "cruise control" switches can be used to cause the "check engine" light to flash "active" fault codes (see the 3176 Truck Engine, Operation and Maintenance Manual). The (7X1055) 3176 Digital Diagnostic Tool (DDT) can also be used to identify "active" fault codes.The 3176 ECM will log and store "intermittent" fault codes. These "intermittent" fault codes can be retrieved even though the power to the engine is shut off. To display "active" or "intermittent" fault codes, the (8T8697) Electronic Control Analyzer Programmer (ECAP) must be used.Step 3. Check The Customer Specified Parameters:Verify with the driver and/or customer that the correct customer specified parameters have been programmed into the 3176 electronic system. Unsatisfactory engine and/or vehicle operation may be caused by incorrect programming.Step 4. Use The Troubleshooting Modules:These troubleshooting modules (Electronic Troubleshooting, Mechanical Troubleshooting, Performance Troubleshooting, OEM Systems Troubleshooting, and Jake Brake Troubleshooting) have been written to find a faulty component in the least number of steps. If a fault has been detected, begin with the corresponding 3176 Fault Code Test Procedure in the electronic troubleshooting module. If a fault has not been detected, begin with the most appropriate Operational Test Procedure of the electronic troubleshooting module or refer to the mechanical, performance, OEM systems, or Jake Brake troubleshooting module(s) with respect to the type of engine or vehicle operation problem encountered.
