EPS Unit Ground Circuit Test
1. Disconnect the EPS ground connector (GDN)
2. Test for continuity between PINS to battery
ground.
EPS GND connector pin A + Battery GND
EPS GND connector pin B+ Battery GND
The voltage should be
Continuity (close to 0
Ω
)
▪ If there is NO continuity or a high resistance is
measured, check wires and connector pins
from EPS unit to chassis ground post.
Replace or repair defective parts and reset
faulty codes.
▪ If there is good continuity, carry out the
following EPS UNIT COMMUNICATION LINK
(CAN) CONTINUITY TEST.
EPS Unit Communication Link (CAN)
Continuity Test
NOTE:
EPS unit must receive an RPM signal to
provide power steering assist.
▪ Disconnect the EPS control connector and the
diagnostic connector.
▪ Test continuity of CAN Bus Wires at PINS.
EPS control connector (pin C) + diagnostic
connector (pin 1) = Below 1
Ω
EPS control connector (pin D) + diagnostic
connector (pin 2) = Below 1
Ω
▪ If resistance measured is out of specification,
check wires and connector pins. Carry out
repairs as required and reset faulty codes.
▪ If resistance measured is good, replace the
EPS unit and reset faulty codes.
