TROUBLESHOOTING
NOTE: The EPS assembly is not serviceable and
must not be disassembled or EPS warranty will be
voided.
1. Check 30-amp EPS fuse and EPS relay (primary
coil: 150 ohms ± 10%, secondary resistance <1 ohm
with primary energized).
2. With the ignition off, disconnect 2-pin connector on
the EPS assembly and connect a volt meter set to DC
voltage to the harness (black meter lead to BLK and
red meter lead to ORG/BRN).With the ignition
switch in the ON position, the meter should read bat-
tery voltage (if correct voltage is not present, check
connections and wiring harness).
3. With ignition switch off, disconnect the 8-pin con-
nector on the EPS assembly and connect a volt meter
set to DC voltage to the harness (red meter lead to
the ORG wire and black meter lead to battery
ground.) With the ignition switch in the on position,
the meter should read battery voltage (if correct volt-
age is not present, check for loose fittings or connec-
tions in the wiring harness).
NOTE: If after completing the preceding tests and
possible solutions with normal results an EPS issue
persists with active DTCs C1301-C1305, 1316, or
C1326-C1329 confirmed by CATT II, the EPS assem-
bly must be replaced (see Steering/Body/Controls).
Ignition Switch
The ignition switch, dash switches, front accessory con-
nectors, and front switched accessory connector can be
accessed from under the dash.
VOLTAGE
NOTE: Perform this test on the harness connector.
1. Set the meter selector to the DC Voltage position.
2. Connect the red meter lead to the red wire; then con-
nect the black meter lead to battery ground.
3. Meter must show battery voltage.
NOTE: If the meter shows no battery voltage, trou-
bleshoot the main 30 amp fuse, the battery, or the
main wiring harness.
4. Connect the red meter lead to the red/black wire;
then with the black lead grounded, turn the ignition
switch to the ON position. The meter must show bat-
tery voltage.
5. Connect the red meter lead to the yellow/green wire;
then with the black lead grounded, turn the ignition
switch to the START position. The starter should
engage and the meter must show battery voltage.
NOTE: When the starter is engaged, battery voltage
will be approximately 10.5 DC volts.
Ignition Coil
The ignition coil is mounted under the seat base below
the driver’s seat.
VOLTAGE
Primary Coil
1. Set the meter selector to the DC Voltage position;
then disconnect the two wires from the coil.
2. Connect the red tester lead to the orange wire and the
black tester lead to ground.
3. Turn the ignition switch to the ON position. The
meter must show battery voltage.
Secondary Coil
1. Connect the primary ignition coil connector. Remove
the spark plug cap from the spark plug.
2. Connect the spark plug cap to Ignition Test Plug or
other suitable tool; then ground the tool away from
the spark plug hole. While turning the engine over,
check for sufficient spark.
RESISTANCE
NOTE: For these tests, the meter selector should be
set to the OHMS position.
Primary Winding
1. Connect the red tester lead to one terminal; then con-
nect the black tester lead to the other terminal.
CAUTION
Do not attempt to check resistance of the EPS motor (2-pin
input receptacle). There are internal capacitors holding a
charge that can cause internal damage to an ohmmeter.
CAUTION
If CATT II has confirmed an active DTC relating to the
CAN communication wires, use extreme caution when
testing the wires. Do not probe the ECM connector with
meter leads; instead use a small T-pin or other suitable
testing component to make light and proper contact.
CAUTION
Never disconnect the ECM connector with the battery
cables installed onto the battery.
CAUTION
Disconnect the injector connector(s) before performing
the following procedure.
CAUTION
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
