If screw driver does not indicate coil is energized:
a.
Make certain the solenoid being checked is the
1401 03 for solenoid valve #1
correct one according to the speed range and
1401 05 for solenoid valve #1
direction conditions shown in table above.
1401 06 for solenoid valve #1
b.
Check ECM for Diagnostic/Fault Codes.
1402 03 for solenoid valve #2
c.
If there are no codes, the problem is in the elec-
trical circuit. Troubleshoot the circuit using the
