Question about Precor EFX 546i Elliptical Version 4

Precor Error 12, Watchdog (Lower PCA)
1. A failure in the lower PCA overloads the low voltage power supply and causes it to drop below the preset level.
2. A fault in the interconnect cable (upper PCA to lower PCA) causing the low voltage power supply of the lower PCA to be too low.
3. A failure in the upper PCA that overloads the lower PCA low voltage power supply causing it to be too low.
External causes may make the error appear intermittently.
