DTC 1–1 Motor System Short Circuit
STEP ACTION VALUE(S) YES NO
1. Turn the starter switch off.
2. Disconnect the actuator connector C–37.
3. Measure resistance between actuator side connector
terminal 1 and 2.
NOTE: If control plate position is fully opened or fully
closed, resistance can not be measured.
Is the resistance within range specified in the value(s)
column?
Measure continuity between harness side connector C–37
terminal 1 and the ground, terminal 2 and the ground, and
terminal 1 and 2.
Are the results same as specified in the value(s) columns?More than 4.2

2. Disconnect the actuator connector C–37.
3. Measure resistance between actuator side connector
terminal 3 and 4.
Is the resistance within range specified in the value(s)
column?
1. Disconnect the brake switch connector B–13.
2. Check continuity between switch side connector terminal 2
and 3.
Is there continuity between terminals?
1. Reconnect the brake switch connector B–13.
2. Check continuity between harness side connector B–9
terminal 6 and connector C–37 terminal 3, connector C–37
terminal 4 and connector B–9 terminal 8.
