ANTI-LOCK BRAKING SYSTEM (ABS)

35B-27

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.

STEP 5. Check the harness wires 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.
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

P.00E-2

STEP 6. Check the harness wires between M-ASTC-ECU
connector E-119 terminal 27 and ABS sensor <front: RH>
connector A-37 terminal 1 or M-ASTC-ECU connector
E-119 terminal 28 and ABS sensor <front: RH> connector
A-37 terminal 2.
NOTE: After inspecting M-ASTC-ECU connector E-119, inter-
mediate connector A-03 and ABS sensor <front: RH> connec-
tor A-37, inspect the wire. If M-ASTC-ECU connector E-119,
intermediate connector A-03 and ABS sensor <front: RH> con-
nector A-37 are damaged, repair or replace them. Refer to
GROUP 00E, Harness Connector Inspection
