Ron Ananian, The Car Doctor -June 27, 2026 - Hour 1 - No Codes. No Clues. Just Good Diagnostics.

A late-model Ford Edge had everyone stumped. Multiple repair shops, multiple replacement parts, no check engine light, and no diagnostic trouble codes-yet it still refused to start.

Ron explains why the best diagnostics begin before the engine is ever cranked, using live scan tool data like coolant temperature, ambient air temperature, battery voltage, fuel pressure, and barometric pressure to verify what the PCM believes is happening. It's a lesson in real-world troubleshooting that every technician-and every vehicle owner-can appreciate.

Also this hour:

• A discussion on complete automatic transmission fluid exchange procedures.
• A Hyundai Palisade with excessive oil consumption and what owners should expect from the manufacturer.
• A Kia Sportage with stubborn brake bleeding issues after multiple hydraulic repairs.
• Why diagnostics should always begin by identifying what's working correctly before chasing what's broken.

As Ron reminds listeners:

"Tell me what's good... and I'll tell you what's bad."
