If communication is normal: Inspect the DLC3 on the
original vehicle.
If communication is still not possible: The problem is
probably in the tester itself. Consult the Service
Department listed in the instruction manual.
6. BATTERY VOLTAGE
Standard battery voltage:
11 to 14 V
If the voltage is below 11 V, replace or recharge the
battery before proceeding.
7. MIL (Malfunction Indicator Lamp)
(a) The MIL is illuminated when the ignition switch is
first turned ON (the engine is not running).
(b) The MIL should turn OFF when the engine is
started. If the MIL remains illuminated, the diagnosis
system has detected a malfunction or abnormality in
the system.
HINT:
If the MIL is not illuminated when the ignition switch
is first turned ON, check the MIL circuit (see page
ES-430).
8. ALL READINESS
For the vehicle, using the intelligent tester allows
readiness codes corresponding to all DTCs to be read.
When diagnosis (normal or malfunctioning) has been
complete, readiness codes are set. Select the following
menu items on the intelligent tester: ENHANCED OBD II
/ MONITOR STATUS.

DTC CHECK / CLEAR
NOTICE:
When the diagnosis system is changed from normal
mode to check mode or vice versa, all DTCs and freeze
frame data recorded in normal mode are erased. Before
changing modes, always check and make a note of any
DTCs and freeze frame data.
HINT:
• DTCs which are stored in the ECM can be displayed on
the intelligent tester. The intelligent tester can display
current and pending DTCs.
• Some DTCs are not set if the ECM does not detect the
same malfunction again during a second consecutive
driving cycle. However, such malfunctions, detected on
only one occasion, are stored as pending DTCs.
1. CHECK DTC (Using intelligent tester)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Turn the tester ON.
(d) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CURRENT
CODES or PENDING CODES.
(e) Check the DTC(s) and freeze frame data, and then
write them down.
(f) Check the details of the DTC(s) (see page ES-56).
2. CLEAR DTC (Using intelligent tester)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Turn the tester ON.
(d) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CLEAR CODES.
(e) Press the YES button.
3. CLEAR DTC (Without using intelligent tester)
(a) Perform either of the following operations.
(1) Disconnect the cable from the negative (-)
battery terminal for more than 1 minute.
(2) Remove the EFI and ETCS fuses from the
engine room relay block (located inside the
engine compartment) for more than 1 minute.

FREEZE FRAME DATA
1. DESCRIPTION
Freeze frame data records the engine conditions (fuel
system, calculated load, engine coolant temperature,
fuel trim, engine speed, vehicle speed, etc.) when a
malfunction is detected. When troubleshooting, it can
help determine if the vehicle was running or stopped, the
engine was warmed up or not, the air-fuel ratio was Lean
or Rich, and other data from the time the malfunction
occurred.
HINT:
If it is impossible to duplicate the problem even though a
DTC is detected, confirm the freeze frame data.
The ECM records engine conditions in the form of freeze
frame data every 0.5 seconds. Using the intelligent
tester, 5 separate sets of freeze frame data can be
checked.
– 3 data sets before the DTC was set.
– 1 data set when the DTC was set.
– 1 data set after the DTC was set.
These data sets can be used to simulate the condition
of the vehicle around the time of the occurrence of the
malfunction. The data may assist in identifying the
cause of the malfunction, and in judging whether it
was temporary or not.

OPEN switch (or TILT UP switch) is pressed for a maximum of 0.3
seconds. Sliding roof stops as soon as switch is released.
Auto slide open and close This function causes sliding roof to be fully opened (or closed) when
SLIDE OPEN switch (or TILT UP switch) is pressed for a minimum of
0.3 seconds
Manual tilt up and down This function causes sliding roof to tilt up (or tilt down) when TILT UP
switch (or SLIDE OPEN switch) is pressed for a maximum of 0.3
seconds
Auto tilt up and down This function enables sliding roof to tilt up (or down) when TILT UP
switch (or SLIDE OPEN switch) is pressed for a minimum of 0.3
seconds.
Jam protection function The jam protection function automatically stops sliding roof, or stops
sliding roof and makes it open halfway (or fully tilts it upward) if a
foreign object gets jammed in sliding roof during auto close operation
(or auto tilt down operation).
Key off operation Key off operation function makes it possible to operate sliding roof for
approximately 45 seconds after ignition switch is turned off if front
doors are not opened
