BRAKES
1 . CHECK VALVE RELAY COIL (ON ABS CON-
TROL UNIT SIDE)
1) Turn ignition switch OFF .
2) Disconnect ABS control unit connector .
3) Disassemble connector . (Refer to No . T6A1 .)
4) Measure resistance between ABS control unit termi-
nals.
Connector fr terminal/Specified Resistance :
(R7) No. 17 - No. 27/80 - 90 f2
2. CHECK HYDRAULIC UNIT VALVE RELAY
1) Disconnect connector from hydraulic unit.
2) Measure resistance between hydraulic unit termi-
nals.
Terminal/Specified Resistance :
(To F43) No. 1 - (To R1) No. 11/1 Mfg min .
3. CHECK VALVE RELAY AS A SINGLE UNIT
1) Remove valve relay.
2) Attach circuit tester probes to terminals, as shown in
Figure .
B4-539
Fig . 171
3) Measure resistance between respective terminals .
Terminal/Specified Resistance :
No. 87 - 30/0 f2(when 12 volts applied)
No . 87 - 30/1 MCI(when no voltage is applied)
No. 87a - 30/1 Mil (when 12 volts applied)
No. 87a - 30/0 f2(when no voltage is applied)
4 . CHECK HYDRAULIC UNIT VALVE RELAY COIL
1) Disconnect connector from hydraulic unit.
2) Measure resistance between hydraulic unit termi-
nals .
Terminal/Specified Resistance:
(To R1) No. 6 - No.12/80 - 90 f2
When resistance checks out "Not OK", check relay as a
single unit.
3) Disconnect connectors from ABS control unit and
hydraulic unit . Measure resistance between connectors.
Connector Fr terminal/Specified Resistance:
(131) No. 6 - (137) No. 17/0 0
(R1) No. 12 - (R7) No. 27/0 f2
(R1) No. 6-Body/1 Mfg min.
(R1) No. 12- Body/1 MQ min.
If resistance checks out "OK", replace hydraulic unit ; if
"Not OK", repair harness/connector between ABS
control unit and hydraulic unit.
5 . CHECK AND REPAIR POWER HARNESS
1) Turn ignition switch ON .
2) Measure resistance between hydraulic unit connec-
tor and ground .
Connector fr terminal/Specified Voltage:
(F43) No . 1/10 - 12 V
