A

N/CHG PORT ENGAGE-
MENT ERROR
(Signal stuck high)

• At the start of charging or during charging, 

the EVSE connection detection signal volt-
age is approximately 4.8 V or more, or 1.0 
V or less, continuously for 3 seconds or 
more.

• During normal charging, the EVSE con-

nection detection signal voltage is approxi-
mately 3.3 V or more continuously for 3 
seconds or more.

• Harness and connector

(Normal charge port circuit is 
open or shorted.)

• Normal charge port
• EVSE
• PDM (Power Delivery Module)

B

N/CHG PORT ENGAGE-
MENT ERROR
(Signal invalid)

During normal charging, the EVSE connec-
tion detection signal voltage is approximately 
3.7 – 4.8 V continuously for 100 seconds or 
more.

• Harness and connector

(Normal charge port circuit is 
open or shorted.)
