Battery Charger Coupler Temperature C Too High
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
The coupler C temperature exceeds the safety threshold during charging. Contact resistance increased or charging current too high.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.

Many vehicles show no symptom at all beyond the warning light. The absence of a symptom does not mean the fault is not real.
| # | Cause | How often | Component |
|---|---|---|---|
| 1 | Coupler contacts oxidised - high resistance | Very common | — |
| 2 | Charging current above coupler rating | Common | — |
Ordering reflects how often each cause is responsible in general, not a probability for your vehicle. Confirm by testing.
