Normal Charge Does Not Start

Symptom Possible cause Action
Normal charge does not start. Normal charge start conditions are not satisfied. VCM recognizes that the selector lever is in a range other than P range. Electric shift system error. Perform self-diagnosis of Electric shift control module.
- Power switch is not OFF. Normal operation.
- VCM receives a charge stop request signal from PDM (Power Delivery Module). Check to see if charge stop conditions are satisfied. Refer to NORMAL CHARGE CONTROL .
VCM recognizes that quick charge connector and normal charge connector are connected simultaneously. Abnormal connection detection circuit of quick charge port. Check quick charge port.
Abnormal PDM (Power Delivery Module). Perform self-diagnosis of PDM (Power Delivery Module).
VCM prohibits charging. Fail-safe of VCM. FAIL-SAFE
VCM recognizes that normal charge connector is not connected. Abnormal connection detection circuit of normal charge port. Check normal charge port.
Abnormal PDM (Power Delivery Module). Perform self-diagnosis of PDM (Power Delivery Module).
VCM recognizes that a PWM signal is not received from EVSE. AC power, no input.
(Disconnect from outlet)
Check outlet.
AC power, no input.
(Blackout)
Check AC power.
EVSE does not transmit a PWM signal. Perform self-diagnosis of PDM (Power Delivery Module).
Abnormal PDM (Power Delivery Module).
- Timer charge is set.
  • Cancel timer charge setting.
  • Turn ON the immediate charging switch.
Judged as fully-charged. - Li-ion battery is fully charged. Normal operation.
Symptom Possible cause Action
Normal charge does not start. EVSE does not activate. EVSE detects electric leakage
  • Plug EVSE alone into an outlet (AC source) and check that the "Fault"  lamp on EVSE does not blink  .

    If the lamp blinks, replace EVSE.

  • Check that no electric leakage exists between EVSE control box and PDM (Power Delivery Module) or in the PDM (Power Delivery Module) itself.
EVSE has a malfunction Plug EVSE alone into an outlet (AC source) and check that the "Fault"  lamp of EVSE does not turn ON  .
If the lamp turns ON, replace EVSE.
EVSE not energized Plug EVSE alone into an outlet (AC source) and check that the "Ready"  lamp of EVSE turns ON  .
If the lamp does not turn ON, replace EVSE.
EVSE communication line has a malfunction Plug EVSE alone into an outlet (AC source) and check that the "Fault"  lamp on EVSE does not blink  .
If the lamp blinks, replace EVSE.
