(c)Inspect the battery voltage. Battery voltage: 11 to 14 V
If voltage is below 11V, recharge the battery before proceeding.
(d)Check the CHK ENG.
(1)The CHK ENG lamp comes on when the ignitionswitch is turned ON and the engine is not running.
HINT:
If the CHK ENG is not illuminate, troubleshoot the combination
meter.
(2)When the engine is started, the CHK ENG shouldgo off. If the lamp remains on, it means that the diag-
nosis system has detected a malfunction or ab-
normality in the system.
2.DTC CHECK (Normal Mode):
NOTICE:
Hand±held tester only:
When the diagnosis system is switched from the normal
mode to the check mode, it erases all DTCs and freeze
frame data recorded in the normal mode. So before switch-
ing modes, always check the DTCs and freeze frame data,
and then write them down.
(a)Checking DTCs using the hand±held tester. (1)Connect the hand±held tester to the DLC3.
(2)Turn the ignition switch ON and switch the hand±held tester main switch ON.
(3)Use the hand±held tester to check the DTCs and freeze frame data and then write them down. If you
need help with the hand±held tester, refer to the
hand±held tester's instruction book).
(4)See page 05±544 to confirm the details of the
DTCs.
(b) Clearing the DTCs using the hand±held tester: (1) Connect the hand±held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) When operating the hand±held tester to erase thecodes, the DTCs and freeze frame data will be
erased. (See the hand±held tester's instruction
book for operating instructions.)
(c) Clearing the DTCs not using the hand±held tester:
(1) Disconnect the battery terminal or remove the EFIand ETCS fuses from the engine room R/B for more
than 60 seconds.

5. CHECK FOR INTERMITTENT PROBLEMS
Hand±held tester only:
By putting the vehicle's ECM in the check mode, the 1 trip detection logic is possible instead of the 2 trip
detection logic, and the sensitivity to detect faults is increased. This makes it easier to detect intermittent
problems.
(a) Clear the DTCs (See step 2).
(b) Set the check mode (See step 3).

(b) Duty signal from terminal M of the generator does not

Glow plug

ECM
MONITOR DESCRIPTION
When starting a cold engine, the ECM supplies the current to the glow plug for a certain period of time. As
the supplying current to the glow plug is terminated, the large current is suddenly cut off, therefore the battery
voltage then varies and also terminal M output (duty ratio) of the generator varies. If these variations are not
occurred when the glow plug is turned from ON to OFF, or vice±versa, the ECM realizes that the current has
not been supplied to the glow plug, and interprets this as open malfunction of the glow plug or glow plug
circuit.

4INSPECT GLOW PLUG ASSY
(a)Check the glow plug for resistance. (1)Check that there is resistance between the glow
plug terminal and ground.
Standard resistance: Approx. 1.1

NOTICE:

Be careful not to damage the glow plug pipes as it
could cause an open circuit or shorten life of the glow
plugs.

Avoid getting oil and fuel on the glow plug when
cleaning.

During inspection, be sure to wipe off any oil of the
terminal and bakelite washer with a dry cloth.

Do not apply more than 11 V to the glow plug as it
could cause an open circuit.
