P0DE5 Charge Status Indicator B Control Circuit/Open

Check engine lightOn
EmissionsNot relevant
Drive cycleNot required

P0DE5 flags an interrupted drive circuit for charge status indicator B, a second lamp or LED that tells the owner whether the vehicle is charging, for instance one at the charge port next to the one on the dashboard. Which light gets the letter B is up to the maker. No manufacturer documents P0DE5 publicly. GM's tables for the Chevrolet Volt and Cadillac ELR only cover indicator A (P0D2C): the hybrid controller samples the LED driver every 100 ms, needs 40 bad results out of 50 and checks for a short to battery or an open line while the LED is commanded off. In the current code set, shorts on B have their own codes, P0E41 and P0E42, so P0DE5 narrows the fault to a break: a cut wire, a loose connector or a dead LED. Charging itself still works.

Likely causes

Broken wire or unplugged connector to indicator B
Burnt-out LED or failed indicator unit
Corroded contacts in the weather-exposed charge port area
Failed output driver in the controlling module

Symptoms

  • Charge status indicator B stays dark while charging
  • Charging works normally
  • Warning lamp possible depending on the manufacturer
