ABS Function Starts Operating (Pressure Holds)
Front RH brake caliper
• Since the ABS IN valve and the ABS OUT valve are cl
osed, the front RH brake caliper, master cylinder, and
reservoir are blocked. This maintains fluid pressure applied on the front RH brake caliper.
Front LH brake caliper
• Since the ABS IN valve and the ABS OUT valve are cl osed, the front LH brake caliper, master cylinder, and
reservoir are blocked. This maintains fluid pressure applied on the front LH brake caliper.
Rear RH brake caliper
• Since the ABS IN valve and the ABS OUT valve are cl osed, the rear RH brake caliper, master cylinder, and
reservoir are blocked. This maintains fluid pressure applied on the rear RH brake caliper.
Rear LH brake caliper
• Since the ABS IN valve and the ABS OUT valve are cl osed, the rear LH brake caliper, master cylinder, and
reservoir are blocked. This maintains fluid pressure applied on the rear LH brake caliper.

SYSTEM DIAGRAM
• By preventing wheel lock through brake force (brake flui d pressure) control that is electronically controlled by
detecting wheel speed during braking, stability during em ergency braking is improved so that obstacles can
be avoided by steering operation.
• During braking, control units calculate wheel speeds , and transmit pressure increase, hold or decrease sig-
nals to actuator portion according to wheel slip status.
• The following effects are obtained by preventing wheel lock during braking.
- Vehicle tail slip is prevented during braking when driving straight.
- Understeer and oversteer tendencie s are moderated during brak-
ing while cornering.
- Obstacles may be easily bypassed by steering operation during
braking.
• CONSULT can be used to diagnose the system.
• Fail-safe function is adopted. When a malfunction occurs in ABS
function, the control is suspended for VDC function, TCS function
and ABS function. However, EBD function operates normally.
Refer to BRC-29, "VDC/TCS/ABS : Fail-safe"

CAUTION:
• When replacing the ABS actuator and electric unit (c ontrol unit), the calibration of the ABS actuator
and electric unit (control unit) is required. Refer to BRC-57, "Description"
.
• Before servicing, disconnect the ba ttery cable from negative terminal.
• To remove brake tubes, use a suitable tool (flare nut wrench) to prevent flare nuts and brake tubes
from being damaged. To install, use su itable tool (flare nut torque wrench).
• Do not apply excessive impact to ABS actuator and elect ric unit (control unit), such as by dropping
it.
• Do not remove and install ABS actuator and el ectric unit (control unit) by holding harness.
• After work is completed, bleed air from brake tubes. Refer to BR-14, "Bleeding Brake System"
.
• After installing harness connector on the ABS act uator and electric unit (control unit), make sure
connector is securely locked.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.
REMOVAL
1. Disconnect battery cable from negative terminal. Refer to PG-73, "Removal and Installation (Battery)".

L TERMINAL CIRCUIT (OPEN)
DescriptionINFOID:0000000009460663
The “L” terminal circuit controls the charge warning
lamp. The charge warning lamp turns ON when the igni-
tion switch is set to ON or START. When the generator is providing sufficient voltage with the engine running,
the charge warning lamp turns OFF. If the charge warn ing lamp illuminates with the engine running, a malfunc-
tion is indicated.
Diagnosis ProcedureINFOID:0000000009460664
Regarding Wiring Diagram information. Refer to CHG-12, "Wiring Diagram".
1.CHECK “L” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check if “L” terminal is clean and tight.

Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair “L” terminal connection. Confirm repair by performing complete Charging system test
using EXP-800 NI or GR8-1200 NI (if available). Refer to applicable Instruction Manual for proper
testing procedures.
2.CHECK “L” TERMINAL CIRCUIT (OPEN)
1. Disconnect the generator connector.
2. Apply ground to generator harness connector terminal.
3. Check condition of the charge warning lamp with the ignition switch in the ON position.
Does it illuminate?
YES >> “L” terminal circuit is normal. Refer to CHG-17, "Work Flow (With EXP-800 NI or GR8-1200 NI)" or
CHG-20, "Work Flow (Without EXP-800 NI or GR8-1200 NI)"
.
NO >> GO TO 3.
3.CHECK HARNESS CONTI NUITY (OPEN CIRCUIT)
1. Disconnect the battery cabl e from the negative terminal.
2. Disconnect the combination meter connector.
3. Check continuity between generator harness connector and combination meter harness connector.
is the inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace the harness or connectors.
4.CHECK HARNESS CONTI NUITY (OPEN CIRCUIT)
Check continuity between combination me ter harness connector and fuse block (J/B).
