P0D89 reports lost continuity in the second output channel, B, of the charge port status indicator. Where an indicator has several channels, they usually stand for different colours or segments, as in the multi-colour port lighting of a supplier patent; which one is B depends on the vehicle, and no manufacturer documents this code publicly. For diagnosis the pattern across channels helps: if only B is open while A and C work, the break lies in the B branch or its LED; if P0D86 and P0D8C are stored at the same time, a shared connector, supply or ground at the inlet is more likely. CARB lets makers combine open and shorted output faults in one code, so not every vehicle separates them. The visible effect is a missing colour or segment at the port; charging continues.

Likely causes

Break in the channel B wire or its connector pin
Failed LED or segment of channel B
Shared connector or ground at the inlet (when A and C are also affected)

Symptoms

  • One colour or segment of the port lighting missing
  • Charging works normally
