D: TRANSFER CLUTCH PRESSURE TEST
Check transfer clutch pressure in accordance with the fol-
lowing chart in the same manner as with line pressure.

ST 498575400 OIL PRESSURE GAUGE ASSY
AWD mode:“D”range
FWD mode:“P”range, engine speed 2000 rpm
CAUTION:
Before setting in FWD mode, install spare fuse on FWD
mode switch.
Unit: kPa (kg/cm2, psi)

If oil pressure is not produced or if it does not change in the
AWD mode, the duty solenoid C or transfer valve assem-
bly may be malfunctioning. If oil pressure is produced in the
FWD mode, the problem is similar to that in the AWD
mode.
E: ROAD TEST
1. GENERAL
Road tests should be conducted to properly diagnose the
condition of the automatic transmission.
CAUTION:
When performing test, do not exceed posted speed
limit.

CHECK POWER SUPPLY FOR RELAYS.
Turn ignition switch to OFF.
: Is the fuse in power supply circuit broken?
: Replace the fuse.
: Go to step10BQ3.
OBD0535
10BQ3CHECK MAIN FAN RELAY 1, SUB FAN
RELAY 1 AND MAIN FAN RELAY.
1) Remove main fan relay 1. (With A/C models only)
2) Measure resistance between main fan relay 1 termi-
nals.
: Terminal
No. 1—No. 3:
Is the resistance between 87 and 107Ω?
: Go to next step 3).
: Replace main fan relay 1.
OBD0536
3) Remove sub fan relay 1. (With A/C models only)
Remove main fan relay. (Without A/C models only)
4) Measure resistance between sub fan relay 1 or main
fan relay terminals.
: Terminal
No. 1—No. 3:
Is the resistance between 83 and 117Ω?
: Go to step10BQ4.
: Replace sub fan relay 1.

10. Diagnostics Chart with Trouble Code

2. HOW TO READ TROUBLE CODE OF INDICATOR
LIGHT
The AT OIL TEMP indicator light flashes the code corre-
sponding to the faulty part.
The long segment (1.2 sec on) indicates a“ten”, and the
short segment (0.2 sec on) signifies a“one”.
B3M0193A
E: CLEAR MEMORY
Current trouble codes shown on the display are cleared by
turning the ignition switch OFF after conducting on-board
diagnostic operation. Previous trouble codes, however,
cannot be cleared since they are stored in the TCM
memory which is operating on the back-up power supply.
These trouble codes can be cleared by removing the speci-
fied fuse (located under the right lower portion of the instru-
ment panel).
CLEAR MEMORY:
Removal of No. 14 fuse (for at least one minute)

The No. 14 fuse is located in the line to the memory
back-up power supply of the TCM and ABS/TCS control
module. Removal of this fuse clears the previous trouble
codes stored in the TCM and ABS/TCS control module
memory.

Be sure to remove the No. 14 fuse for at least the speci-
fied length of time. Otherwise, trouble codes may not be
cleared.
