3. Wire harness and ABS wire harness
• Remove the ABS motor relay and ABS motor fuse, and then check for continuity between the
red/blue terminal of ABS wire harness and the starter relay ABS motor fuse terminal "1" (ABS wire
harness side) shown in the illustration.
Refer to "CIRCUIT DIAGRAM (1/2) (FJR13A)" on page 8-119, "CIRCUIT DIAGRAM (2/2) (FJR13A)"
on page 8-121, "CIRCUIT DIAGRAM (1/2) (FJR13AE)" on page 8-123, and "CIRCUIT DIAGRAM
(2/2) (FJR13AE)" on page 8-125.
• Check for continuity between the positive battery terminal and the ABS motor fuse terminal "2" (bat-
tery side) shown in the illustration.
• Disconnect the ABS ECU and ABS motor relay from ABS wire harness, and then check for continuity
between the white/black terminals, between the red/white terminals, between the red/black termi-
nals, and between the red/blue terminals.
Malfunction code 34 (ABS motor is defective (ABS motor keeps rotating and will not stop).)
1. ABS motor
• Check if the ABS motor coupler located under the hydraulic unit is connected properly.
• Check the ABS motor for continuity.
Refer to "MAINTENANCE OF THE HYDRAULIC UNIT" on page 8-132.
2. ABS wire harness
• Disconnect the ABS motor coupler, and then check for continuity between the black/white terminal
of the ABS motor coupler of ABS wire harness and the negative battery terminal.
• Disconnect the ABS ECU couplers, and then check for continuity between the red/black terminal of
the ABS ECU coupler and the red/black terminal of the ABS motor coupler.
Refer to "MAINTENANCE OF THE ABS ECU" on page 8-132.
• Remove the ABS motor relay and check for continuity between the red/white terminal of the ABS
motor coupler of the ABS wire harness and positive battery terminal.
3. ABS motor relay
• Check if the ABS motor relay operates correctly.
Refer to "MAINTENANCE OF THE ABS MOTOR RELAY" on page 8-132.
Malfunction code 35 (Disconnection is detected in the ABS ECU and hydraulic unit solenoid cir-
cuit.)
1. Coupler between the battery and the hydraulic unit (solenoid)
• Check if the coupler is connected properly.
2. ABS wire harness
• Check the red/white leads for continuity between "1" and "2", between "1" and "3", and between "1"
and "4" of the hydraulic unit solenoid circuit.
