Title: 3UR-FE STARTING: STARTER: INSPECTION; 2015 MY Tundra [08/2014 - ]
INSPECTION
1. INSPECT STARTER ASSEMBLY
CAUTION:
As a large electric current passes through the cable during this inspection, a thick cable must be used.
Otherwise, the cable may become hot and cause injury.
NOTICE:
These tests must be performed within 3 to 5 seconds to avoid burning out the coil.
(a) Perform a pull-in test.
(1) Remove the nut, and then disconnect the field coil lead wire from terminal C.
(2) Connect the battery to the magnet starter switch as
shown in the illustration. Then check that the clutch pinion
gear moves outward.
If the clutch pinion gear does not move outward, replace
the magnet starter switch assembly.
(b) Perform a holding test.
(1) When the battery is connected as above with the clutch
pinion gear out, disconnect the negative (-) lead from
terminal C. Check that the pinion gear remains out.
If the clutch pinion gear moves inward, replace the
magnet starter switch assembly.
(c) Inspect the clutch pinion gear return.

(1) Disconnect the negative (-) lead from the starter body.
Check that the clutch pinion gear returns inward.
If the clutch pinion gear does not return inward, replace
the magnet starter switch assembly.
(d) Perform an operation test without load.
(1) Connect the field coil lead wire to terminal C with the nut.
Torque:
10 N·m {102 kgf·cm, 7ft·lbf}
(2) Mount the starter in a vise between aluminum plates.
(3) Connect the battery and an ammeter to the starter as
shown in the illustration.
(4) Check that the starter rotates smoothly and steadily while the pinion gear is moving outward. Then
measure the current.
Standard current:
150 A or less at 11.5 V
If the result is not as specified, replace the starter assembly.
2. INSPECT MAGNET STARTER SWITCH ASSEMBLY
(a) Check if the pull-in coil has an open circuit.
(1) Measure the resistance according to the value(s) in the
table below.
Standard Resistance:
TESTER CONNECTION
CONDITION
SPECIFIED CONDITION
Terminal 50 - Terminal C
Always
Below 1 Ω
If the result is not as specified, replace the magnet

starter switch assembly.
(b) Check if the holding coil has an open circuit.
(1) Measure the resistance according to the value(s) in the
table below.
Standard Resistance:
TESTER CONNECTION
CONDITION
SPECIFIED CONDITION
Terminal 50 - Switch body
Always
Below 2 Ω
If the result is not as specified, replace the magnet
starter switch assembly.
3. INSPECT STARTER ARMATURE ASSEMBLY
If necessary, replace the starter armature assembly.
(b) Measure the resistance.
(1) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
TESTER CONNECTION
CONDITION
SPECIFIED CONDITION
Segment - Segment
Always
Below 1 Ω
If the result is not as specified, replace the starter armature assembly.
(2) Measure the resistance according to the value(s) in the
table below.
Standard Resistance:
TESTER CONNECTION
CONDITION
SPECIFIED CONDITION
Segment - Coil core
Always
10 kΩ or higher
If the result is not as specified, replace the starter
armature assembly.
