1. What does P1A7F mean?
P1A7F is identified in a Mitsubishi technical service bulletin as “CMU10 Cell Voltage Sensor.” Verified applicability is the 2016 Mitsubishi i-MiEV sold in the US.
2. Technical explanation
NHTSA-hosted Mitsubishi TSB-19-54-005 lists P1A7F as the diagnostic trouble code for the CMU10 Cell Voltage Sensor. The supplied excerpt states its trouble-judgment check conditions include three seconds after the electric motor switch is turned ON, or three seconds after the main drive lithium-ion battery starts charging. The excerpt is incomplete after an additional condition, so no further setting criteria are established by verified evidence.
3. What system is affected?
CMU10 Cell Voltage Sensor; the supplied evidence does not establish a broader system name.
4. How serious is this code?
Unknown. Severity is not established by the verified evidence.
5. Symptoms you may notice
- Not yet established by verified evidence.
6. Possible causes
- A CMU10 Cell Voltage Sensor DTC is identified by the verified bulletin. The underlying failure cause is not yet established by the supplied verified evidence.
7. Can I still drive the vehicle?
Unknown. Whether the vehicle can be driven is not established by verified evidence.
8. Can I charge the vehicle?
Unknown. Whether the vehicle can be charged is not established by verified evidence.
9. What you can safely do
- Have the vehicle assessed by a qualified Mitsubishi EV service provider.
- Do not attempt high-voltage battery diagnosis, disassembly, or repair based on this information.
10. Step-by-step troubleshooting
- The verified bulletin identifies check conditions of three seconds after the electric motor switch is turned ON, or three seconds after the main drive lithium-ion battery starts charging.
- Further diagnostic steps are not yet established by the supplied verified evidence.
11. When to contact service
Service need is listed as unknown in the supplied diagnostic record. Because this DTC concerns a cell-voltage sensor identified in a main drive lithium-ion battery bulletin, qualified Mitsubishi EV service assessment is appropriate.
12. What the service center may check
- Confirm whether P1A7F is present using suitable diagnostic equipment.
- Review Mitsubishi TSB-19-54-005. Additional service checks are not established by the supplied excerpt.
13. Possible repair or resolution
- The supplied source summary includes the phrase “replace the main drive lithium-ion battery assembly,” but the provided excerpt does not establish the precise conditions under which that resolution applies to P1A7F. Do not treat battery replacement as confirmed for every occurrence of this code without the complete applicable bulletin procedure.
