Check/Cause
(1) when starter switch is OFF, measure voltage between
battery relay primary terminal COM and chassis ground.
Standard voltage : 12 V or more
(2) when starter switch is ON, measure voltage between
battery relay coil terminal BR inlet wire LgR and coil
ground terminal E.
Standard voltage : 12 V or more
(3) when starter switch is ON, measure voltage between
battery relay secondary terminal NO and chassis
ground.
Standard voltage : 12 V or more
• If above items (1) and (2) are OK and item (3) is NG,
battery relay is faulty.
(1) when starter switch is ON, measure voltage between
F-R lever switch terminal COM inlet wire wY and
chassis ground.
Standard voltage : 12 V or more
(2) when starter switch is ON, measure voltage between
F-R lever switch terminal NC outlet wire Bw and
chassis ground.
Standard voltage : 12 V or more
• If above item (1) is OK and item (2) is NG, F-R lever
switch is faulty.
parking interlock relay terminal 1 inlet wire BrR and
chassis ground.
Standard voltage : 12 V or more
(2) when starter switch is ON, measure voltage between
parking interlock relay terminal 3 inlet wire BW and
chassis ground.
Standard voltage : 12 V or more
(3) when starter switch is ON, measure voltage between
parking interlock relay terminal 5 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,
parking interlock relay is faulty.
(1) when starter switch is ON, measure voltage between
parking brake switch terminal 1 inlet wire WB and
chassis ground.
Standard voltage : 12 V or more
(2) when starter switch is ON, measure voltage between
parking brake switch terminal 2 outlet wire BrR 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.
• Measure resistance of harness connecting between
terminals.
Standard resistance : 10 Ω or less
• If resistance is abnormal, harness is faulty.
