Is DTC P1440 indicated?
Y E S — G o t o step 6.
NO—Intermittent failure, system is OK at this t i m e .
Check for poor connections or loose terminals at
the MPI m o d u l e , the U/V/W phase motor current
sensor, and the M C M . B
6. Turn the ignition switch OFF.
7. Turn the battery m o d u l e switch OFF (see page 12-4).
8. Check the motor power cable connection at the

NO—Repair connection in the cable, then go to
step 35.
9. Turn the ignition switch OFF.
10. Remove the IPU lid (see page 12-140).
11. Check the MPI module, the U/V/W phase motor
current sensors, and the M C M connections.
Are the connections OK ?
YES—Go to step 12.
NO—Repair connection in the cable, then go to
step 35.
12. Check the motor power cable connection at the MPI
m o d u l e .
Is the connection OK?
Y E S — G o t o step 13.
NO—Repair connection in the cable, then go t o
step 35.
13. Disconnect M C M connector A (31P), the MPI
