NOTE!
•
Read off the other fault codes for the VECU.
•
Check the particular connectors during the fault
tracing for oxidation and switch resistance. For
detailed circuit information, refer to “VNL, VNM Elec-
trical Schematics,” Group 37.
Appropriate Tests in the VCADS
Pro Tool
The following test(s) are useful for closely examining the
component’s function:
N/A No test currently available.
Measurement at the Component’s
Connector, to the VECU
Note: Faults in the wiring harness to the VECU can
damage the component. Therefore, a check of the com-
ponent should also be made if any of the measurement
values deviate from the expected value.
1
Disconnect the connector at the range
inhibitor solenoid valve. Install 2–pin
breakout harness J–42472 to the
wiring harness end only.

Turn the ignition key to the OFF posi-
tion.
3
Connect an ohmmeter and measure
the resistance.

Connect a voltmeter from the breakout
harness terminals to the alternate
ground and measure the voltage.

Check of Component
Range Inhibitor Solenoid
Note: Faults in the component can be caused by faults
in the wiring harness of the VECU. A check of the wiring
harness should also therefore be made before connect-
ing a new component.
1
Disconnect the connector at the range
inhibitor solenoid valve.
2
Install 2–pin breakout harness J–
42472 between the solenoid valve and
the wiring harness.

3
Turn the ignition key to the ON posi-
tion.
