Sensor Circuit High Voltage
1. Turn the ignition switch ON (II).
2. Check the W PHASE MOTOR CURRENT SENSOR in
the DATA LIST w i t h the HDS.
Is about 4.84 V or more indicated?
Y E S — G o t o stepS.
NO—intermittent failure, system is OK at this t i m e .
Check for poor connections or loose terminals at
the W phase motor current sensor and the M C M . •
3. Turn the ignition switch OFF.
4. Turn the battery m o d u l e switch OFF (see page 12-4).
5. Remove the IPU lid (see page 12-140).
6. Disconnect the W phase m o t o r current sensor 3P
connector.
7. Turn the ignition switch ON (II). Measure voltage
between W phase motor current sensor 3P
connector terminals No. 1 and No. 2.

16. Check for Temporary DTCs or DTCs w i t h the HDS.
Are any Temporary DTCs or DTCs indicated?
YES—If DTC P0A65 is indicated, check for poor
connections or loose terminals at the W phase
motor current sensor and the M C M , then go to
step 1. If any other T e m p o r a r y DTCs or DTCs are
indicated, go to the indicated D T C s
t r o u b l e s h o o t i n g .
