1WARNING
Use only gray pin probes from HARNESS CONNECTOR

Diagnostic Notes
The reference numbers below correlate with the circled num-
bers on the Test A.9 flow charts.
1.
Set up wheel speed sensor test as follows:
a. Obtain two gray pin probes, two gray socket probes
and two patch cords from HARNESS CONNECTOR
TEST KIT (Part No. HD-41404A).
b. Disconnect front wheel speed sensor connector
[167]. Maintaining polarity, use patch cords to con-
nect probes to pin and socket housings as shown in
A of Figure A-22.
2. Use HARNESS CONNECTOR TEST KIT (Part No. HD-
41404A), gray pin probes and patch cord.
1WARNING
Ground
Use only gray pin probes from HARNESS CONNECTOR
TEST KIT (Part No. HD-41404A) on small terminals (1-7,
10-23) of ABS Module connector [166B], and dark blue
pin probes on large terminals (8-9, 24-25). Use of the
wrong probes can damage terminals causing insufficient
or excessive current to be passed to solenoid valves

and/or pump, a condition which could cause the ABS to
malfunction, possibly resulting in death or serioius
injury.

1WARNING
Use only gray pin probes from HARNESS CONNECTOR
TEST KIT (Part No. HD-41404A) on small terminals (1-7,
10-23) of ABS Module connector [166B], and dark blue
pin probes on large terminals (8-9, 24-25). Use of the
wrong probes can damage terminals causing insufficient
or excessive current to be passed to solenoid valves
and/or pump, a condition which could cause the ABS to
malfunction, possibly resulting in death or serioius
injury.
