ANTI-LOCK BRAKING SYSTEM (ABS)
35B-23
STEP 3. Inspect the ABS sensor or ABS rotor.
Refer to
Check items:
• ABS sensor internal resistance: 1.0 − 1.5 kΩ
• Insulation between the ABS sensor body and the connector
terminals
• Toothed ABS rotor check
Q: Is the ABS sensor or ABS rotor damaged?
YES : Replace it and then go to Step 11.
NO : Go to Step 4.
STEP 4. Check ABS sensor circuit at the M-ASTC-ECU
connectors E-119 and E-120.
(1) Disconnect connectors E-119, E-120 and measure at the
harness side.
(2) Measure the resistance between the M-ASTC-ECU
connector E-119 terminals 30 and 31, 27 and 28 or M-
ASTC-ECU connector E-120 terminals 46 and 47, 60 and
61.
Standard Value: 1.0
− 1.5 kΩ
Q: Is the resistance between M-ASTC-ECU connector E-119
terminals 30 and 31, 27 and 28 or M-ASTC-ECU
connector E-120 terminals 46 and 47, 60 and 61 within
the standard value?
When resistances between all terminals are within the
standard value. : Go to Step 9.
When resistance between M-ASTC-ECU connector E-
119 terminals 30 and 31 is not within the standard value.
:
Go to Step 5.
When resistance between M-ASTC-ECU connector E-
119 terminals 27 and 28 is not within the standard value.
:
Go to Step 6.
When resistance between M-ASTC-ECU connector E-
120 terminals 46 and 47 is not within the standard value.
:
Go to Step 7.
When resistance between M-ASTC-ECU connector E-
120 terminals 60 and 61 is not within the standard value.
:
Go to Step 8.

NOTE: After inspecting M-ASTC-ECU connector E-119, inter-
mediate connector A-03 and ABS sensor <front: LH> connector
A-24, inspect the wire. If M-ASTC-ECU connector E-119, inter-
mediate connector A-03 and ABS sensor <front: LH> connector
A-24 are damaged, repair or replace them. Refer to GROUP
00E, Harness Connector Inspection
.Then go to Step
11.
Q: Is the harness wire between M-ASTC-ECU connector E-
119 terminal 30 and ABS sensor <front: LH> connector
A-24 terminal 1 or M-ASTC-ECU connector E-119
terminal 31 and ABS sensor <front: LH> connector A-24
terminal 2 damaged?
YES : Repair it and go to Step 11.
NO : Go to Step 11.
