Disconnect the vehicle’s battery for 20 minutes (negative terminal first). Reconnect and test-drive. If DTC060AF1 returns immediately or within a few miles, proceed.

| Step | Action | Success rate | |------|--------|---------------| | 1 | Replace battery (AGM/EFB) + reset BMS | ~60% | | 2 | Clean/tighten battery terminals and main ground strap | ~15% | | 3 | Repair broken LIN bus wire (often chafed near alternator) | ~10% | | 4 | Replace alternator (or regulator if separate) | ~10% | | 5 | ECU software update / replace UPC module | ~5% |

Corroded ground points (especially the main chassis ground near the ABS unit) or a weak battery/alternator can cause voltage drops. The ESP module requires stable 12–14.5V. Deviations as short as 100 milliseconds can log this fault.

In plain terms: The engine ECU detects an inconsistent or missing signal from the throttle system, often related to the accelerator pedal position sensor (also called pedal potentiometer) or the throttle body position sensor.
