MECHANICAL/HYDRAULIC DIAGNOSIS
CHECK TRANS INDICATOR CHART
AUTOMATIC TRANSMISSION (4L30-E) 7 A-23
I PERFORM PRELIMINARY INSPECTION FIRST!
When the "CHECK TRANS" indicator is flashing, it
indicates that a problem related to the trans­
mission, the Transmission Control
Module (TCM),
or the vehicle harness has occurred:
The system is
now operating in a "BACKUP MODE"
where the risk of further damaging the transmission
has been reduced. The vehicle may be shifted
manually.
If the initial problem is intermittent or seldom,
switching OFF/ON the engine might allow normal
operation again until the problem re-occurs.
I "CHECK TRANS" indicator flashing
I NO DTC I
I
Use "CHECK TRANS" CHECK in
Electronic Diagnosis section in this
manual
BACKUP MODE PATTERN:
-No automatic shifting
- Manual shifting only
-"CHECK TRANS" Flashing
Read and record the Diagnostic
Trouble Codes {DTCI stored by TCM.
WARNING: Disconnecting battery or TCM will result in loss of stored trouble code{s).

"CHECK TRANS" CHECK
1. CASE it is ON during 2 to 3 seconds at ignition
(or when the engine is cranked) but it is OFF
after (Fig. 7A-8a). The indicator is working
normally GOTO DIAGNOSTIC CHECK.
2. CASE it is flashing and the flash is 0.2 seconds
ON and 0.2 seconds OFF always when ignition
is on (engine cranked or not). This means that
there is a malfunction. GOTO DIAGNOSTIC
CHECK.

4. CASE it is staying ON always when Ignition is
ON.
(1) This means that connection between the
Lamp and the TCM is shorted to ground
(Fig. 7 A-8c).
(2) Verify if instrument panel terminal 7 of
connector 1-1 is shorted to ground.
(3) Verify if the TCM connector C-91 terminal
C10 is shorted to ground.
(4) Verify that the instrument panel terminal 6
of connector 1-1 is connected to Battery.
(5) IF problem solved: GOTO CHECK TRANS
INDICATOR.
NO: GOTO TCM MEM-CAL REPLACE­
MENT.
Fig. 7A-8a 5. CASE it is staying OFF with the ignition ON
(engine OFF). 3. CASE the CHECK TRANS indicator is flashing
always and the flash is 0.4 seconds ON and 0.4
second OFF.
(1) This means that the Transmission Control
Module (TCM) is in flashing code mode.
This mode is only used for service. This
mode is set when the Terminal 1 of
diagnostic connector C-92 is set to
ground. To go out of this mode see Fig.
7A-8b.
(2) Check
if terminal 1 of diagnostic con­
nector C-92 is shorted to ground. (Voltage
is
about 0 volts when there is a short to
ground instead of 5 volts).
(3) Check if TCM terminal 016 has the same
problem.
(4) Remove the short circuit to ground due to
wiring problems.
(5) IF problem solved: GOTO CHECK TRANS
INDICATOR.
NO: GOTO TCM MEM-CAL REPLACE­
MENT.
(1) This means that connection between the
Lamp and the TCM is shorted to battery or
opened (Fig. 7 A-8c).
(2) Verify if instrument panel terminal 7 of
connector 1-1 is shorted to battery or
open.
(3)
Verify if the TCM connector C-91 terminal
C1 0 is shorted to battery or open.
(4)
Verify that the instrument panel terminal 6
of connector 1-1 is connected to Battery. If
not check the Fuses and the connections
(terminal 10 of connector H-25) voltage.
(5) IF problem solved: GOTO CHECK TRANS
INDICATOR.
NO: GOTO TCM MEM-CAL REPLACE­
MENT.

7A..J52 AUTOMATIC TRANSMISSION (4l30-E)
TECH1 CONNECTION
1. The Electronic Diagnosis Equipment is
composed of:
(1) TECH1 (J-38770-1)
hand-held scan tool
(Fig. 7 A-9).
(2)
TECH1 self-test adapter.
(3) Manufacturer's operating instructions.
Fig. 7A-9
2. Battery Cable Adapter
(1) This harness (J-38770-4) allows you to
power the TECH1 from vehicle battery.
(2) Remark:
lsuzu vehicles do not have power
to the cigarette lighter during cranking.
3. Transmission Cartridge
The cartridge
(TK025008-1) must be inserted
into the TECH1 for the 4L30-E transmission
diagnosis (Fig. 7 A-9a).
Fig. 7A-9a
4. TECH 1 Adapter
The adapter
(TA-02279-B) connects the single
TECH1 vehicle connector to single common
diagnostic connector for the 4L30-E Trans­
mission
Control Module (TCM) and the Engine
Control Module (ECM) called DATA LINK
CONNECTOR (C-9)
(white) (Fig. 7A-9b).
5. Connecting the TECH1 ~
(1) Always observe the instructions in the
TECH1 and Transmission Cartridge Oper-
ator's
Manual.
(2) Make sure the vehicle ignition is off.
(3) Install the adapter cable between the
TECH1 vehicle connector and the TCM/
ECM
DATA LINK CONNECTOR (C-9).
(4) Connect the battery cable adapter to the
vehicle battery and plug the TECH1 into its
"cigarette lighter" receptacle.
Fig. 7A-9b
6. DVOM
When instructed to use a voltmeter or ohm­
meter within a troubleshooting procedure, use
only a high-impedance DVOM (Digital Volt
Ohm
Meter) such as J-39200 or equivalent.
