Problem: Right Motor, Faulty Armature Circuit (10)
(1) Situation
Indication: "10" display. Vehicle operation disabled.
(2) Possible cause
(3) How the error code is triggered
(4) Checks
Disconnect battery plug. Check line and regeneration contactor tips for wire breakage and melting. Make sure each
contactor tip moves freely. See page 1-37.
No broken or shorted wire Broken or shorted wire
(5)Check right motor armature wiring for wire breakage
and shorting. See page 3-15.
(18) Correct or replace faulty components (regeneration
contactor, line contactor).
(6) Check T1R IGBT, D1R diode, D2 diode and head
capacitor for abnormality. Check wiring between D1R
and logic card for abnormality.
See pages 1-46, 1-43 and 1-35.
Acceptable Unacceptable
(17) Correct or replace right motor, or correct or replace
wiring.
(7) Check drive board. Check wiring between T1R and
drive board for abnormality. See pages 1-44 to 1-48.
(16) Replace faulty components (T1R, D1R, D2, head
capacitor) or wiring.

(6) Check T1L IGBT, D1L diode, D2 diode and head
capacitor for abnormality. Check wiring between D1L
and logic card for abnormality.
See pages 1-46, 1-43 and 1-35.
Acceptable Unacceptable
(17) Correct or replace left motor, or correct or replace
wiring.
(7) Check drive board. Check wiring between T1L and
