Original Symptoms of Alternator Pulley Cap Failure

Before its cancellation, TSB 08-217-25 REV. A described several customer-reported symptoms that could indicate an alternator pulley cap failure. These issues would typically manifest as multiple indicators and messages on the Instrument Panel Cluster (IPC), notably without generating any Diagnostic Trouble Codes (DTCs). Owners might have observed a range of problems, including:

• "Vehicle will not start due to a depleted battery."
• "Noise heard from the engine compartment."
• Illumination of a "Battery Symbol" warning light.
• A "Service Transmission" message.
• A "Check Diesel Exhaust Fluid (DEF) System" warning.
• An "Anti-Lock Brake System (ABS) Service Required" message.
• A "Service Park Brake" message.
• An "Engfine Stop/Start (ESS) Unavailable 'Service Battery'" message.

These symptoms collectively pointed to a potential electrical system malfunction, often linked to the alternator's performance.
