If there is NO continuity or a high resistance is
measured, check wires and connector pins from
DPS unit to chassis ground post. Replace or re-
pair defective parts and reset fault codes.
If there is good continuity, carry out the following
DPS UNIT COMMUNICATION LINK (CAN) CON-
TINUITY TEST .
NOTE: This test may also be carried out by con-
necting a 12 Vdc test light between each GDN
connector pin and the battery (+) positive termi-
nal. The test light must come on bright.
DPS Unit Communication Link (CAN)
Continuity Test
NOTE: DPS unit must receive an RPM signal to
provide power steering assist.
Disconnect the DPS control connector and the di-
agnostic connector.
Test continuity of CAN Bus Wires at DPS1-C and
DPS1-D.

If resistance measured is out of specification,
check wires and connector pins. Carry out re-
pairs as required and reset fault codes using
B.U.D.S software.
If resistance measured is good, replace the DPS
unit and reset fault codes using B.U.D.S software.
DPS System Load Test
If the charging system cannot sustain normal volt-
age when the DPS is operating, DPS ASSIST may
be greatly reduced or nonexistent. Carry out the
following steps.
1. Connect the red lead of a
TER (P/N 529 035 868)
box battery terminal.
2. Connect the black multimeter lead to the bat-
tery ground.
