Scan tool: read DTC P2E36, freeze frame data and related codes
Verify battery voltage and state of charge before tests
Monitor Charger B enable status/command with manufacturer scan tool (active test if available)
Measure voltage on enable wire at charger and at control module connector with ignition ON
Check continuity and resistance between control module pin and charger enable pin
Inspect connectors, pins and wiring for corrosion, looseness, or damage

Enable signal expected: Low = 0 V (inactive); High = battery voltage (~9–14 V) or logic 5 V depending on design — consult OEM data
Typical current draw on enable line: very low (mA) — line is a control/driver output, not a power feed
If PWM-controlled, frequency and duty vary by manufacturer — check OEM specification
Short-to-ground will show near 0 V at both charger and control module with ignition on
Open circuit will show no continuity between control module and charger enable pin

Safety: Disable high-voltage systems if vehicle is HV/electric. Disconnect battery only as required by OEM procedures.
Retrieve DTC, freeze-frame and related codes. Note ignition status and conditions when fault recorded.
Verify battery voltage >= 12 V (or manufacturer specified). Charge battery if low and retest.
With ignition ON (engine off unless specified), monitor Charger B enable status via scan tool and attempt an active enable command if available.
Measure voltage at the charger enable terminal and at the control module pin. Record voltages with command OFF and ON.
If enable voltage does not change when commanded, measure continuity between control module pin and charger connector. Repair open circuits.
If continuity is good but voltage remains low, check for shorts to ground on the enable wire (backprobe and measure resistance to ground).
Inspect and test fuses and relays in the charger enable supply path; replace if faulty.
Inspect connectors for corrosion/damaged pins; repair or replace wiring harness as needed.
If wiring and fuses are good and the control module does not output the enable signal, verify control module power/ground and related inputs. Consider module reprogramming or replacement per OEM guidance.
If control module output is correct but charger does not enable, suspect internal Charger B fault — test charger module or replace.
Clear codes and perform a road or system cycle to confirm repair. Re-scan for recurrence.
