TRANSMISSION CONTROL SWITCH CIRCUIT
CIRCUIT DESCRIPTION
When shifting the shift lever into S position using the transmission control switch, it is possible to shift in 1
to 4 positions.
Shifting º+º once changes up 1 shift range position, º±º once changes down 1 shift range position respective-
ly.

INSPECTION PROCEDURE
1 CHECK ECM
(a) Turn the ignition switch to ON.
(b) Measure the voltage between terminals SPT1 and E1 of
the ECM.
OK:
Shift rangeSpecified condition
Except S positionBelow 1 V
S position7.5 to 14 V
NG Go to step 6
OK
2 CHECK ECM
(a) Measure the voltage between terminals E1 and that
SFTU as well as SFTD of the ECM.
OK:
Shift rangeTester connectionSpecified condition
Shift to º+º
(Up shift)SFTU ± E1Below 1.5 V
S positionSFTU ± E17.5 to 14 V
Shift to º±º
(Down shift)SFTD ± E1Below 1.5 V
S positionSFTD ± E17.5 to 14 V
OK NORMAL

3 INSPECT SHIFT LOCK CONTROL UNIT ASSY(TRANSMISSION CONTROL
SWITCH)
(a) Turn the ignition switch to OFF.
(b) Disconnect the transmission control switch connector.
(c) Measure the resistance between terminals E and SFTU
as well as SFTD of the transmission control switch con-
nector.
OK:
Shift rangeTester connectionSpecified condition
Shift to º+º
(Up shift)SFTU ± EContinuity
S positionSFTU ± ENo continuity
Shift to º±º
(Down shift)SFTD ± EContinuity
