CHECK:
Measure the voltage between terminal PWR of the ECM con-
nector and body ground when the PWR mode switch is set to
the PWR (POWER) position and NORM (NORMAL) position.

CIRCUIT DESCRIPTION
When 2nd start mode is selected with the pattern select switch, the ECM cont\
rols the solenoid valves and
the transmission starts from 2nd gear.
In D position, the transmission automatically shifts up through 3rd to O\
/D as usual.
In 2nd position, the transmission is held in 2nd gear.

As an example, the blinking patterns for normal code and
codes 11 and 21 are shown in the illustration.
(6) Code are explained in the code table on page
DI−196 .
(7) After completing the check, disconnect terminals Tc
and E
1, and turn off the display.
If 2 or more malfunctions are indicated at the same time the low-
est numbered DTC will be displayed 1st.
(c) Clear the DTC.
(1) Confirm that the center differential is free.
(2) Using SST, connect terminals Tc and E
1 of the
DLC1 and remove the short pin from the DLC1.
SST 09843−18020
(3) Turn the ignition switch ON.
(4) Clear the DTC stored in ECU by depressing the
brake pedal 8 or more times within 3 seconds.
(5) Check that the warning light shows the normal
code.
(6) Remove the SST from the terminals of the DLC1.
SST 09843−18020
(7) Connect the short pin to the DLC1.
HINT:
Cancellation can also be done by removing the ECU −B fuse,
but in this case, other memory systems will also be cancelled
out.

SRS Warning Light System Malfunction (Does not light up, when
ignition switch is turned to ACC or ON.)
CIRCUIT DESCRIPTION
The SRS warning light is located on the combination meter.
When the SRS is normal, the SRS warning light lights up for approx. 6 seconds after the \
ignition switch is
turned from LOCK position to ACC or ON position, and then turns off automatically.
If there is a malfunction in the SRS, the SRS warning light lights up to\
inform the driver of the abnormality.
When terminals Tc and E1 of the DLC1 are connected, the DTC is displayed by the blinking\
of the SRS warn-
ing light.
WIRING DIAGRAM
Refer to page DI−274 for the WIRING DIAGRAM.
INSPECTION PROCEDURE
1 Check ECU−B Fuse.
PREPARATION:
Remove ECU−B fuse.
CHECK:
Check continuity of ECU −B fuse.
OK:
Continuity
HINT:
Fuse may be burnt out even if it appears to be OK during
visual inspection.
If fuse is OK, install it.
NG Go to step 5.
OK
2 Preparation. (See step 1 on page DI−271)
