P0D89: Battery Charger Coupler Status Indicator Control Circuit B/Open

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.

High severity. Can I keep driving?If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.

Symptoms

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

Most 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)

What to check, in order

Start with the simplest. You can tick off each step.

Read the codes with a hybrid-compatible scanner and write down the freeze frame data
Check the continuity of the wire between the component and the control module.
Make sure the battery cooling air intake is clean
Check the 12 V auxiliary battery, which can also trigger warnings
Leave any high-voltage measurements to a specialized repair shop

Good to know

Repair difficulty: medium

What each character of P0D89 means

P: Powertrain: engine and transmission
0: Generic code: same on every make
D: Subsystem depends on the code range
89: Specific fault in that system

Frequently asked questions

Can I keep driving with code P0D89?

If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.

What causes code P0D89?

The most common causes are: 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).
