Input Speed Sensor
S Inspect resistance of each input speed senor be-
tween terminals.
Notice :
S Make sure to inspect resistance again at 20°C
(68°F) when resistance differ from standards ex-
cept 20°C (68°F).
S It might become infinity ohm when inspect resist-
ance at higher temperature.
Action : If the result of inspection is bad, replace ISS.
Transmission Range (TR) Switch
S Remove TR switch connector and inspect continuty
each range according to the conection chart.
Action : If the result of inspection is bad, replace the TR
switch.
Transmission Fluid Temperature Sensor
S Inspect the resistance between the terminals of
TFT sensor at 10°C (50°F) and 110°C (230°F).
Standard Value
10°C (50°F)11 0°C (230°F)
5.80~7.09 kΩ0.23~0.263 kΩ
Action : If the result of inspection is bad, replace the TFT
sensor.

Shift Solenoid (NO.1,2), Timing Solenoid,
Lock–Up Solenoid
1. Inspect the resistance of each shift solenoid be-
tween the terminal and the body earth.
Action : If the result of inspection is bad, replace each so-
lenoid.
Notice :
S Make sure to inspect resistance again at 20°C
(68°F) when resistance differ from standards ex-
cept 20°C (68°F).
S It might become infinity ohm when inspecting resist-
ance at higher temperature.
2. Inspect the operation of each shift solenoid.
S Solenoid (No.1,2), Lock–up solenoid (Normal
open type)
No battery connection

Battery connectionLeak air
Action : If the result of inspection is bad, replace the each
solenoid.
Notice : Do not damage the strainer on the tip of solenoid
while inspecting operation.
Pressure Control Solenoid
S Inspect the resistance of each pressure control so-
lenoid between terminals.
Action : Repalce the valve body assembly. (No replace-
ment of solenoid by itself)
Notice :
S Make sure to inspect resistance again at 20°C
(68°F) when resistance differ from standards ex-
cept 20°C (68°F).
S It might become infinity ohm when inspecting resist-
ance at higher temperature.

* Description of Type
S Type A : TCM will request the illumination of MIL and store DTC when TCM detects a failure on the first ignition
cycle.
S Type B : TCM will request the illumination of MIL and store DTC when TCM detects failures on two consecutive
ignition cycle.
S Type D : TCM will not request the illumination of MIL or hold lamp, but will store DTC when TCM detects a failure
on the first ignition cycle.

SYSTEM VOLTAGE LOW
Conditions for Setting the DTC
S System voltage is too low.
S TCM detects that voltage is less than 9 volts for 0.5
seconds continuously.
S Engine revolution is 600 rpm or greater.
Action Taken When the DTC Sets
S TCM will request the illumination of MIL and store
DTC when TCM detects failures on two consecu-
tive ignition cycle.
Conditions for Clearing the DTCS The TCM turns off the MIL when no further failures
detected for three consecutive ignition cycles.
S The scan tool can clear the DTC from the TCM his-
tory.
S The TCM clears the DTC from the TCM history
memory after forty consecutive warm up cycles
without fault.
Cause of Failure
