INSPECTION PROCEDURE
1 DRIVING TEST
(a) Start the engine.
(b) Turn the ECT SNOW switch ”OFF” (Normal drive mode).
(c) Confirm vehicle response by driving from a parked position to fully depressing the accelerator pedal.
(d) Turn the ECT SNOW switch ”ON” and perform the same check as (c).
Confirm that there is a difference between ECT SNOW switch ”ON” and ”OFF”.
HINT:
S Driving test should be done on a paved road (a nonskid road).
S Make sure not to use the TRAC system when testing a vehicle equipped with one.
OK:
There is a difference in acceleration between ”ON” and ”OFF”.

TRANSMISSION CONTROL SWITCH CIRCUIT
CIRCUIT DESCRIPTION
When moving the shift lever into the S position using the transmission control switch, it is possible to switch
the shift range position between ”1” (first range) and ”5” (fifth range).
Shifting up ”+” once raises one shift range position, and shifting down ”−” lowers one shift range position.
