Check point
Check/Cause
Action
1. Harness
(1) Measure resistance between traction control box
terminal C1-P2 wire G and fuse box terminal 6 wire G.
Standard resistance : 10 Ω or less
(2) Measure resistance between traction control box
terminal C1-P6 wire LW and backup buzzer switch
terminal NO wire LW.
Standard resistance : 10 Ω or less
(3) Measure resistance between traction control box
terminal C1-P1 wire B and chassis ground wire B.
Standard resistance : 10 Ω or less
If above item (1), (2) or (3) is NG, harness is faulty.
•
Repair or replace
harness.
2. Backup Buzzer Switch
(1) When starter switch is ON, measure voltage between
backup buzzer switch terminal COM inlet wire R and
chassis ground.
Standard voltage : 12 V or more
(2) When starter switch is ON and F-R lever is in reverse
position, measure voltage between backup buzzer
switch terminal NO outlet wire LW and chassis ground.
Standard voltage : 12 V or more
If above item (1) is OK and item (2) is NG, backup buzzer
switch is faulty.
•
Replace backup buzzer
switch.
3. Traction Control Box
(1) When starter switch is ON, measure voltage between
traction control box terminal C1-P2 inlet wire G and
chassis ground.
Standard voltage : 12 V or more
(2) When starter switch is ON and F-R lever is in reverse
position, measure voltage between traction control box
terminal C1-P6 inlet wire LW and chassis ground.
Standard voltage : 12 V or more
(3) Check traction control box terminal C1-P1 wire B is
grounded.
If above item (1), (2) or (3) is NG, traction control box is
faulty.
•
Replace traction control
box.
