Parking brake switch must be released (brake OFF).
Foot brake switch must be ON (Brake pedal is not depressed).
Reference Fig.: 2-4-1
Check point
Check/Cause
Action
1. Brake Solenoid
Disconnect harness and measure resistance of coil.
Standard resistance: 12.3
± 1.2
Ω
If measured resistance is abnormal, brake solenoid is
faulty.
•
•
Replace brake solenoid.
2. Foot Brake Relay
(1) When starter switch is ON, measure voltage between
foot brake relay terminal 1 inlet wire LgR and chassis
ground.
Standard voltage: 12 V or more
(2) When starter switch is ON, measure voltage between
foot brake relay terminal 5 inlet wire Y and chassis
ground.
Standard voltage: 12 V or more
(3) When starter switch is ON, measure voltage between
foot brake relay terminal 3 outlet wire BrW and chassis
ground.
Standard voltage: 12 V or more
If above items (1) and (2) are OK and item (3) is NG, foot
brake relay is faulty.
•
Replace foot brake relay.
3. Foot Brake Switch
(1) When starter switch is ON, measure voltage between
foot brake switch inlet wire WY and chassis ground.
Standard voltage: 12 V or more
(2) When starter switch is ON, measure voltage between
foot brake switch outlet wire LgR and chassis ground.
Standard voltage: 12 V or more
If above item (1) is OK and item (2) is NG, foot brake
switch is faulty.
•
Replace foot brake
switch.
4. Parking Brake Switch
(1) When starter switch is ON, measure voltage between
parking brake switch terminal 1 inlet wire WY and
chassis ground.
Standard voltage: 12 V or more
(2) When starter switch is ON, measure voltage between
parking brake switch terminal 3 outlet wire Y and
chassis ground.
Standard voltage: 12 V or more
If above item (1) is OK and item (2) is NG, parking brake
switch is faulty.
•
Replace parking brake
switch.
5. Harness Connecting
Between Terminals
Measure resistance of harness connecting between
terminals.
Standard resistance: 10 Ω or less
If resistance is abnormal, harness is faulty.
•
•
Repair or replace
harness.
