1997 TOYOTA SUPRA transmission

36SUPRAÐNEW FEATURES
3) ABS ECU
a. Wheel Speed Control
The ECU constantly receives signals form the 4±speed sensors and a deceleration sensor (2JZ±GTE engine model),
and estimates the speed and deceleration rate of the vehicle by calculating the speed and deceleration rate of each
wheel.
b. Initial Check
An initial check is carried out every time once after the engine has started and the initial vehicle speed exceeds 6 km/h
(4 mph).
c. Self±Diagnosis
If the ABS ECU detects a malfunction in the ABS, the ABS warning light and a master warning lights in the
combination meter will light up and alert the driver that a malfunction has occurred. The ECU will also store the codes
of the malfunctions.
 SUSPENSION
1. General
The shock absorber of the 2JZ±GTE engine model with manual transmission has been changed from the
mono±tube, gas±filled shock absorber to the twin±tube, gas±filled shock absorber, which is the same type that is
used on the 2JZ±GE engine model.
The same rubber±integrated ball bushing that is used on the 2JZ±GTE engine model is used for the upper arm
bushing of the rear suspension of the 2JZ±GE engine model.
The brace rod of the rear subframe has been relocated to realize excellent riding comfort, in addition, this provides
excellent stability, an controllability.

The 2 trip repeats the same mode a 2nd time. (However,
the IG switch must be turned OFF between the 1st trip and
2nd trip).
Freeze frame data:
Freeze frame data records the engine condition when a
misfire (DTC P0300 - P0306) or fuel trim malfunction
(DTC P0171, P0172), or other malfunction (first malfunc-
tion only), is detected.
Because freeze frame data records the engine conditions
(fuel system, calculator load, engine coolant tempera-
ture, fuel trim, engine speed, vehicle speed, etc.) when
the malfunction is detected, when troubleshooting it is
useful for determining whether the vehicle was running or
stopped, the engine warmed up or not, the air-fuel ratio
lean or rich, etc. at the time of the malfunction.
Priorities for Troubleshooting:
If troubleshooting priorities for multiple DTC are given in
the applicable diagnostic chart, these should be followed.
If no instructions are given troubleshoot DTC according
to the following priorities.
(1) DTC other than fuel trim malfunction (DTC P0171,
P0172), EGR (DTC P0401, P0402), and misfire
(DTC P0300 - 0306).
(2) Fuel trim malfunction (DTC P0171, P0172) and
EGR (DTC P0401, P0402).
(3) Misfire (DTC P0300 - P0306).
(b) Check the DLC3.
The vehicle's ECM uses V.P.W. (Variable Pulse Width) for
communication to comply with SAE J1850. The terminal
arrangement of DLC3 complies with SAE J1962 and
matches the V.P.W. format.
Terminal No.Connection / Voltage or ResistanceCondition
2Bus  Line / Pulse generationDuring transmission
4Chassis Ground / e Body Ground 1 W or lessAlways
5Signal Ground / e Body Ground 1 W or lessAlways
16Battery Positive / e Body Ground 9 - 14 VAlways
HINT:
If your display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of the OBD II scan tool or
TOYOTA hand-held tester to DLC3, turned the ignition switch
ON and operated the scan tool, there is a problem on the ve-
hicle side or tool side.

If communication is normal when the tool is connected to
another vehicle, inspect DLC3 on the original vehicle.

If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool's instruction manual.

TOYOTA hand-held tester only:
Compared to the normal mode, the check mode has an in-
creased sensitivity to detect malfunctions.
Furthermore, the same diagnostic items which are detected in
the normal mode can also be detected in the check mode.
(a) Check the DTC.
(1) Initial conditions.

Battery positive voltage 11 V or more.

Throttle valve fully closed.

Transmission in park or neutral position.

Air conditioning switched OFF.
(2) Turn ignition switch OFF.
(3) Prepare the TOYOTA hand-held tester.
(4) Connect the TOYOTA hand-held tester to DLC3 at
the lower left of the instrument panel.
(5) Turn the ignition switch ON and switch the TOYOTA
hand-held tester ON.
(6) Switch the TOYOTA hand-held tester normal mode
to check mode. (Check that the MIL flashes.)
(7) Start the engine. (The MIL goes out after the engine
start.)
(8) Simulate the conditions of the malfunction de-
scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTC, etc.
(9) After simulating the malfunction conditions, use the
TOYOTA hand-held tester diagnosis selector to
check the DTC and freezed frame data, etc.
HINT:
Take care not to turn the ignition switch OFF. Turning the ignition
switch OFF switches the diagnosis system from check mode to
normal mode, so all DTC, etc. are erased.
(10) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clear the DTC.
The following actions will erase the DTC and freezed frame
data.
(1) Operating the OBD II scan tool (complying with SAE
J1978) or TOYOTA hand-held tester to erase the
codes. (See the OBD II scan tool's instruction book
for operating instructions.)
(2) Disconnecting the battery terminals or EFI fuse.
NOTICE:
If the TOYOTA hand-held tester switches the ECM from
normal mode to check mode or vice-versa, or if the ignition
switch is turned from ON to ACC or OFF during check
mode, the DTC and freezed frame data will be erased.
