TROUBLE CODE SPN FMI
P-COD-
E
CONDITION
Exhaust Valve
Actuator Over
Current
523958 6 P3026 This trouble code sets if the ECU detects
high current on the EV Actuator Drive
circuit. Can be caused by Damaged
Wiring, Faulty EV Actuator, or ECU /
Connections. Inspect EV Actuator Drive
wires. (White/Green & White/Blue).
Exhaust Valve
Actuator Internal IC
Voltage High
523957 3 P3027 This trouble code sets if the ECU has
detected a Exhaust Valve Actuator internal
IC voltage above 6V. Can be caused by a
faulty ECU.
Exhaust Valve
Actuator Internal IC
Voltage Low
523957 4 P3028 This trouble code sets if the ECU has
detected a Exhaust Valve Actuator internal
IC voltage Below 4V. Can be caused by a
faulty ECU.
Exhaust Valve
Actuator Internal IC
Over Current / Over
Temp
523957 6 P3029 This trouble code sets if the ECU has
detected a Exhaust Valve Actuator internal
IC current above 2A or 200C. Can be
caused by a faulty ECU.
Exhaust Valve
Actuator Internal IC
Communication
Loss
523957 19 P3032 This trouble code sets if the ECU loses
communication with the Exhaust Valve
Actuator IC. Can be cause by a faulty
ECU.
Exhaust Valve
Actuator Position
Sensor Voltage
High
523956 3 P3033 This trouble code sets if the Exhaust Valve
Actuator Position Sensor voltage is
greater than 4.5V for 1 sec. Can be
caused by Damaged wiring, Faulty EV
actuator, or ECU / Connections. Inspect
EV Actuator Position Sensor wires. Power:
Red/White. Ground: Brown/White.
Feedback: Dark Green/Orange.

Actuator Position
Sensor Voltage
Low
523956 4 P3034 This trouble code sets if the Exhaust Valve
Actuator Position Sensor voltage is Less
than 0.4V for 1 sec. Can be caused by
Damaged wiring, Faulty EV actuator, or
ECU / Connections. Inspect EV Actuator
Position Sensor wires. Power: Red/White.
Ground: Brown/White. Feedback: Dark
Green/Orange.
Exhaust Valve
Actuator Abnomral
Rate of Change
523956 10 P3035 This trouble code sets if the Exhaust Valve
Actuator Position Sensor voltage is Less
than 0.4V for 1 sec. Can be caused by
Damaged wiring, Faulty EV actuator, or
ECU / Connections. Inspect EV Actuator
Position Sensor wires. Power: Red/White.
Ground: Brown/White. Feedback: Dark
Green/Orange.
