MIL Request Signal Circuit Voltage Low
2022-2024 Kia EV6 Electric
Description
The PCM has detected a low voltage condition on the MIL (Malfunction Indicator Lamp) request signal circuit. The circuit that controls the Check Engine Light on the instrument cluster is not functioning at the correct voltage.
Symptoms
- Check Engine Light may not illuminate when it should
- Possible false MIL illumination
- Instrument cluster communication issue
Common Causes
- Short to ground in MIL control circuit
- Faulty instrument cluster
- Wiring issue between PCM and instrument cluster
- PCM MIL driver failure
- Corroded connector
Diagnostic Steps
- Check MIL operation with scan tool MIL command
- Inspect wiring between PCM and instrument cluster
- Test MIL circuit for shorts to ground
- Check instrument cluster connector
- Verify PCM MIL output
Repair Notes
Repair the wiring in the MIL control circuit or replace the instrument cluster if it is at fault.
