1. What does P1ABE mean?
For a 2016 Mitsubishi i-MiEV in the US, DTC P1ABE is identified by Mitsubishi’s TSB-19-54-005 as “CMU10 Battery Low Temperature.”
2. Technical explanation
The verified TSB evidence states that P1ABE is a battery-management diagnostic code for CMU10 Battery Low Temperature. The excerpt says the trouble judgment is evaluated 3 seconds after the electric motor switch is turned ON, or 3 seconds after main drive lithium-ion battery charging begins. The supplied excerpt is incomplete after stating that one of certain diagnostic trouble codes is not present; the remaining conditions and diagnostic procedure are not established by the verified evidence provided.
3. What system is affected?
Main drive lithium-ion battery monitoring; specifically CMU10 (Cell Monitoring Unit 10), as identified in TSB-19-54-005.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
- A P1ABE diagnostic trouble code may be stored. No vehicle symptoms are established by the verified evidence provided.
6. Possible causes
- Low battery temperature reported for CMU10, as named in the official TSB.
- Further root causes are not yet established by verified evidence.
7. Can I still drive the vehicle?
Not yet established by verified evidence.
8. Can I charge the vehicle?
Not yet established by verified evidence.
