If NO voltage is measured, test the 40 A DPS fuse
in the rear fuse box (PF2-F3). If good, check wires
and connector pins. Replace or repair defective
parts and reset fault codes.
If battery voltage is measured, carry out the fol-
lowing
DPS UNIT INPUT VOLTAGE TEST (CON-
TROL SIDE)
.
NOTE: This test may also be carried out by con-
necting a 12 Vdc test light between each DPS
PWR connector pins (A and B), and the battery (-)
negative terminal. The test light must come on
bright.
DPS Unit Input Voltage Test (Control
Side)
1. Disconnect DPS CTRL (control) connector and
turn ignition switch ON.
2. Set the ignition switch to ON.
3. Set the engine RUN/STOP switch to RUN.
4. Test for 12 Vdc power to the DPS module at
DPS1-A as per following table.

fuse in front fuse box (PF1-F4). Replace or repair
defective parts and reset fault codes.
If battery voltage is measured, carry out the fol-
lowing
DPS UNIT GROUND CIRCUIT TEST
.
NOTE: This test may also be carried out by con-
necting a 12 Vdc test light between the DPS con-
trol connector (pin A), and the battery (-) negative
terminal. The test light must come on bright.
