Connect the
battery to ter-
minals 6 and
1
2. Check:
• ABS motor relay for continuity
Connect the pocket tester (Ω × 1) to the ter-
minals of the ABS motor relay.
Check for continuity between terminals 1
and 6 of the ABS motor relay.
Tester positive probe → Terminal 1
Tester negative probe → Terminal 6
Tester reading is "∞". → Replace the fail-
Continuity
safe relay.
CAUTION:
_
Do not reverse the connections. If the
pocket tester leads are connected in
reverse to terminals 1 and 6, a correct
pocket tester reading cannot be obtained.
• Connect the positive battery terminal to ter-
minal 6 and the negative battery terminal
to terminal 1, and then check for continuity
between terminals 2 and 5 of the ABS
motor relay.
Tester positive probe → Terminal 2
Tester negative probe → Terminal 5
Tester reading is "∞". → Replace the fail-
safe relay.
CAUTION:
_
• Be sure to connect the pocket tester posi-
tive and negative probes correctly. If the
pocket tester probes are connected in
reverse, the diode of the fail-safe relay
will be broken.
• When connecting the battery and the ABS
motor relay terminals, be careful not to
short-circuit the positive and negative
battery terminals.
