TROUBLE DIAGNOSES
Fail-safe Function (Cont'd)
SHIFT SOLENOID A, B
When a malfunctioning signal of solenoid is input to TCM and ECM-TCM, the gear is shifted as follows.
Normal Abnormal solenoid A Abnormal solenoid B Abnormal solenoid A/B Shift positions A B Gears A B Gears A I3 Gears A 8 Gears
0 0 1 st o-+x 03x - - - -
-- 0: Solenoid ON X: Solenoid OFF -: Abnormal
LINE PRESSURE SOLENOID
When a malfunctioning signal of solenoid is input to TCM and ECM-TCM, the line pressure solenoid is turned
OFF, and the line pressure is set to maximum oil pressure.
LOCK-UP SOLENOID
When a malfunctioning signal of solenoid is input to TCM and ECM.TCM, the lock-up solenoid is turned OFF,
and the lock-up

When a malfunctioning signal of manual mode switch is input to TCM and ECM.TCM, the gear is controlled
with normal "D" position.
SHIFT CONTROL UNIT (Except RB20DE)
When a malfunction occurs in the shift control unit, the shift solenoid NB are turned OFF, and the gear posi-
tion
is controlled with 3rd speed.
TURBINE SENSOR (Except RB20DE)
Controlled by vehicle speed sensor 1 in the same way without turbine sensor

TROUBLE DIAGNOSES
Self-diagnosis
DESCRIPTION
If malfunction should occur in electrical systems, turning ignition switch ON lights M mode switch POWER
indicator lamp
(M-AT Dual matic AfT warning lamp) for 2 seconds, and then flashes the indicator lamp for 8 Gc
seconds. If malfunction does not occur, A/T mode switch POWER indicator lamp (M-AT Dual matic A/T warn-
ing lamp) is turned on for
2 seconds upon turning ignition switch ON. To locate and display the malfunction-
ing part, output the trouble information memory and flash
A/T mode switch POWER indicator lamp (M-AT Dual
matic
A/T warning lamp) by inputting self-diagnostic startup signal.
SELF-DIAGNOSIS PROCEDURE
1. Warm up engine.
2. Repeat ON-OFF cycles of ignition switch for more than once, and turn it OFF at last.
3. Move A/T mode switch to AUTO, and turn overdrive control switch to O/D ON.
4. Turn ignition switch ON with selector lever in "Pn position, and ensure POWER indicator lamp is turned on
for
2 seconds.
5. Turn ignition switch OFF.
6. Move selector lever to "D" position.
7. Turn overdrive control switch O/D OFF.
8. Turn ignition switch ON.
9. Move selector lever to "2" position.
10. Turn overdrive control switch OID ON.
11. Move selector lever to "I" position.
12. Turn overdrive control switch O/D OFF.
13. Depress accelerator pedal fully, and release it.
14. Read flashing status of POWER indicator lamp to complete self-diagnosis procedures.
M-AT
1. Warm up engine.
2. Repeat ON-OFF cycles of ignition switch for more than once, and turn it OFF at last.
3. Turn ignition switch ON with selector lever in "P" position, and ensure dual matic PJT warning lamp is turned
on for
2 seconds.
4. Turn ignition switch OFF.
5. Depress brake pedal, release accelerator pedal, and then move selector lever to "D" position.
6. Turn ignition switch ON.
7. Release brake pedal, and move selector lever to "3" position.
8. While depressing brake pedal with left foot, depress accelerator pedal fully with right foot, and move
selector lever to
"2" position.
9. Read dual matic A/T warning lamp indication to complete self-diagnosis procedures.

HOW TO ERASE SELF-DIAGNOSTIC RESULTS
To facilitate cause investigation of malfunction that is less likely to
reappear, the TCM always stores self-diagnostic results during cus-
tomer operation. This memory cannot be erased even if ignition
switch
is turned ON and OFF repeatedly. To erase the seif-diag-
nostic
results, turn ignition switch
OFF after self-diagnosis has
been performed, or use
"ERASE" function of CONSULT.
