INSPECTION PROCEDURE
1 Read PNP, REVERSE, 2ND and LOW signals.
When using TOYOTA hand±held tester.
PREPARATION:
(a) Remove the DLC3 cover.
(b) Connect a TOYOTA hand±held tester to the DLC3.
(c) Turn the ignition switch ON and TOYOTA hand±held tes-
ter main switch ON.
CHECK:
Shift lever into the P, R, N, 2 and L positions, and read the PNP,
REVERSE, 2ND and LOW signals on the TOYOTA hand±held
tester.
OK:

When not using TOYOTA hand±held tester.
PREPARATION:
Turn the ignition switch ON.
CHECK:
Measure voltage between terminals NSW, 2, L and R of ECM
and body ground when the shift lever is shifted to the following
positions.
OK:
HINT:
*: The voltage will drop slightly due to lighting up of the back up
light.

O/D Cancel Signal Circuit
CIRCUIT DESCRIPTION
While driving uphill with cruise control activated, in order to minimize gear shifting and provide smooth cruis-
ing overdrive may be prohibited temporarily under some condition.
The cruise control ECU sends O/D cut signals to the ECM as necessary and the ECM cancels overdrive
shifting until these signals are discontinued.

O/D Main Switch & O/D OFF Indictor Light Circuit
CIRCUIT DESCRIPTION
The O/D main switch contacts go open when the switch is pushed in and go closed when it is pushed out.
In O/D main switch at OFF position, the O/D OFF indicator light lights up, and the ECM prohibits shifting over-
drive.
