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.

INSPECTION
1. INSPECT STARTER ASSEMBLY
NOTICE:
These tests must be performed within 3 to 5 seconds
to avoid burning out the coil.
(a) Perform the pull-in test.
(1) Disconnect the lead wire from terminal C.
(2) Connect the battery to the magnetic switch as
shown in the illustration. Check that the clutch
pinion gear extends.
If the clutch pinion gear does not move, replace
the magnetic switch.
(b) Perform the hold-in test.
(1) Maintain the battery connections of the pull-in
test above, but disconnect the negative (-) lead
from terminal C. Check that the pinion gear
remains extended.
If the clutch pinion gear returns inward, replace
the magnetic switch.
(c) Check the clutch pinion gear return.
(1) Disconnect the negative (-) lead from the
switch body. Check that the clutch pinion gear
returns.
If the clutch pinion gear does not return,
replace the magnetic switch.
(d) Perform the no-load performance test.
(1) Connect the lead wire to terminal C. Make sure
that the lead is not grounded.
(2) Clamp the starter in a vise.
(3) Connect the battery and an ammeter to the
starter as shown in the illustration.
(4) Check that the starter rotates smoothly and
steadily while the pinion gear is moving out.
Then measure the current.
Standard current:
90 A or less at 11.5 V
If result is not as specified, replace the starter
assembly.

If communication is normal when the tester is connected to
another vehicle, inspect the DLC3 on the original vehicle.
If communication is still not possible when the tester is
connected to another vehicle, the problem is probably in the
tester itself. Consult the Service Department listed in the
tester's instruction manual.
6. CHECK MIL
(a) Check that the MIL illuminates when turning the
ignition switch ON.
If the MIL does not illuminate, there is a problem in
the MIL circuit (see page ES-386).
(b) When the engine is started, the MIL should turn off.
7. ALL READINESS
(a) For this vehicle, using the intelligent tester allows
readiness codes corresponding to all DTCs to be
read. When the diagnosis (normal or
malfunctioning) has been completed, readiness
codes are set. Enter the following menus:
ENHANCED OBD II / MONITOR STATUS.
DTC CHECK / CLEAR
1. CHECK DTC
(a) DTCs which are stored in the ECM can be displayed
with the intelligent tester.
The intelligent tester can display pending DTCs and
current DTCs. Some DTCs are not stored unless a
malfunction is detected in consecutive driving
cycles. When a malfunction is detected in only one
driving cycle, it is stored as a pending DTC.
(1) Connect the intelligent tester to the CAN VIM.
Then connect the CAN VIM to the DLC3.
(2) Turn the ignition switch ON and turn the tester
ON.
(3) Enter the following menus: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CURRENT
CODES (or PENDING CODE).
(4) Confirm the DTCs and freeze frame data and
then write them down.
(5) Confirm the details of the DTCs (see page AX-
35).
NOTICE:
When simulating a symptom with the scan
tool to check for DTCs, use normal mode.
For codes on the DIAGNOSTIC TROUBLE
CODE CHART subject to "2 trip detection
logic", perform the following actions.
Turn the ignition switch OFF after the
symptom is simulated once. Then repeat the
simulation process again. When the
symptom has been simulated twice, the MIL
illuminates and the DTCs are recorded in the
ECM.
