Main Gear Shift Switch Check
1. Disconnect the main gear shift switch connectors.
2. Connect the circuit tester leads to the main gear shift switch 2P
connector.
(When the main gear shift lever is in "NEUTRAL" position)
1. Measure the resistance between terminals.
2. If the continuity is not 0 Ω, the switch is faulty, replace it.
(When the main gear shift lever is in "1st or REVERSE"
position)
1. Measure the resistance between terminals.
2. If the continuity is not infinity, the switch is faulty, replace it.
(When the main gear shift lever is in "2nd or 3rd" position)
1. Measure the resistance between terminals.
2. If the continuity is not infinity, the switch is faulty, replace it.
