Causes

Blown fuse for charger enable circuit
Open or short to ground in enable wiring or connector
Corroded or loose connector at charger or control module
Failed charger enable relay or contactor
Faulty charger control module or vehicle control module output
Software/firmware glitch or incorrect calibration

Symptoms

Onboard charger (Charger A) will not start or fails to enable
No charging or reduced charging rate when connected to EVSE
Charge-inhibit, charging fault or warning lamp/message on dash
Stored DTC(s) related to charger enable or charging system
Possible loss of charging-related vehicle functions or limp mode

What to check

Retrieve and record freeze-frame and related DTCs before clearing
Visually inspect wiring and connectors for damage, corrosion, looseness
Check relevant fuses and relays for continuity and correct operation
Backprobe the charger enable pin at both the charger harness and control module with key ON and during attempted charge
Perform wiggle tests on harnesses while monitoring the enable signal
Check for TSBs or software updates related to charging system

Signal parameters

Signal type: digital enable/command line from vehicle control module to charger
Disabled state: approximately 0 V (or pulled low) expected
Enabled state: approximately battery voltage (~12 V nominal) or control-module supply voltage when active
Diagnostic threshold: circuit voltage below a few volts (typically
Low current; the line is a control/logic feed, not the high-voltage charge current

Diagnostic algorithm

Record DTC and related codes. Attempt to clear codes and see if P0E62 returns during a controlled reproduce (connect charger / request charge).
Safety first: follow high-voltage and workshop safety procedures for hybrids/EVs. Disable high-voltage system if required by service manual before accessing HV connectors.
Visually inspect connectors, pins and wiring between the vehicle control module (BCM/EV ECU) and Charger A. Look for corrosion, water ingress, bent pins or burned insulation.
Check fuses and relays in the charger enable feed. Replace any blown fuses and retest.
With key ON (and high-voltage system in a safe state as required), backprobe the enable terminal at the charger connector. Command the charger ON (via vehicle instrument or scan tool) and measure voltage. If voltage rises to battery voltage, the enable circuit is functioning and the fault may be in the charger input stage.
If enable voltage remains low, backprobe the enable output at the vehicle control module. If module output is low but should be high, suspect module, driver transistor, or software. If module output is high but charger pin is low, suspect short to ground in harness or charger input fault.
Measure resistance from the charger enable terminal to ground with ignition off. A very low resistance indicates a short to ground—isolate by disconnecting connectors and testing sections to find the short.
If wiring checks good and connector pins are clean, swap or bench-test the charger (or control module) per manufacturer procedure or replace the failed component following confirmation of fault location.
After repair, clear codes and verify proper operation by commanding a charge and confirming enable voltage and charger operation. Retest for intermittent faults with wiggle and road/charging simulation.

Likely causes

Wiring short to ground between control module and charger enable pin
Disconnected or corroded connector at charger enable terminal
Faulty control module driver transistor that supplies the enable signal
Blown inline fuse or open relay in the charger enable feed
Charger unit A internal fault pulling the enable line low

Fault status

⚠️ Status

Battery Charger A enable/command circuit voltage is below the required threshold (circuit reads low). Charger A may not engage; charging could be inhibited.
