- How the car detects it
- P0DE0 flags a wiring or driver fault in balancing circuit N, the fourteenth and last letter of the series; the next code, P0DE4, belongs to a different system. Packs with more balancing groups than fourteen must therefore map several groups to one letter or use their own codes. Ford's hybrid BECM is one of the few documented users that fills all fourteen letters, but only with stuck codes, so P0DE0 itself has no public maker source. How a broken balancing terminal is found is shown in Toshiba patent US20130026994A1, where comparing the sense pin with the balancing pin reveals an open connection. CARB 13 CCR 1968.2 requires codes that point to the smallest replaceable unit. Stuck and plausibility faults of N: P0DE1 to P0DE3.
