C0392 01

The TCCM sees an RPS-PWM voltage that does not constantly change, but remains high, >5.0 V, indicating a short to voltage.

C0392 02

The TCCM sees an RPS-PWM voltage that does not constantly change, but remains low, <0.5 V, indicating a short to ground.

C0392 08

The module does not receive a 5-volt reference of 4.8-5.2 volts.
The RPS low reference circuit has an open or high resistance causing a low voltage situation.
