Possible causes
B29A0
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.)
• Normal charge port
