DIAGNOSIS SYSTEM
DESCRIPTION
The ECM contains a built±in self±diagnosis system by which
troubles with the engine signal network are detected and a Mal-
function Indicator Lamp on the instrument panel lights up.
By analyzing various signals as shown in a later table (See page
EG±388) the Engine Control Module (ECM) detects system mal-
functions relating to the sensors or actuators.
In the normal mode, the self±diagnosis system monitors 18
(California specification vehicles) or 17 (except for California and
Canadian specification) items, indicated by code No. as shown in
EG±388. A malfunction indicator lamp informs the driver that a
malfunction has been detected. The lamp goes off automatically
when the malfunction has been repaired, but the diagnostic
trouble code(s) remains stored in the ECM memory (except for
code Nos. 16 and 53). The ECM stores the code(s) until it is
cleared by removing the EFI No. 1 fuse with the ignition switch
OFF.
The diagnostic trouble code can be read by the number of blinks
of the malfunction indicator lamp when TE1 and E1 terminals on
the data link connector 1 or 2 are connected. When 2 or more
codes are indicated, the lowest number (code) will appear first.
In the test mode, 12 (California specification vehicles) or 11 (ex-
cept for California and Canadian specification vehicles) items, in-
dicated by code No. as shown in EG±388 are monitored. If a mal-
function is detected in any one of the systems indicated by code
Nos. 13, 21, 22, 24, 25, 26, 27, 28, 35, 41, 71 and 78 (California
specification vehicles) or 13, 21, 22, 24, 25, 28, 35, 41, 71 and 78
(except for California and Canadian specification vehicles) the
ECM lights the malfunction indicator lamp to warn the technician
that a malfunction has been detected. In this case, TE2 and E1
terminals on the data link connector 2 should be connected as
shown later. (See page EG±386).
In the test mode, even if the malfunction is corrected, the malfunc-
tion code is stored in the ECM memory even when the ignition
switch OFF (except code Nos. 43 and 51). This also applies in the
normal mode. The diagnostic trouble mode (normal or test) and
the output of the malfunction indicator lamp can be selected by
connecting the TE1, TE2 and E1 terminals on the data link con-
nector 2, as shown later.
A test mode function has been added to the functions of the self±
diagnosis system of the normal mode for the purpose of detecting
malfunctions such as poor contact, which are difficult to detect in
the normal mode. This function fills up the self±diagnosis system.
The test mode can be implemented by the technician following the
appropriate procedures of check terminal connection and opera-
tion described later. (See page EG±386) EG±384

Diagnosis Inspection (Normal Mode)
MALFUNCTION INDICATOR LAMP
CHECK
1. The Malfunction Indicator Lamp will come on when the
ignition switch is turned ON and the engine is not running.
HINT: If the malfunction indicator lamp does not light up, pro-
ceed to troubleshooting of the telltale light RH
(See page BE±48).
2. When the engine is started, the malfunction indicator lamp
should go off.
If the light remains on, the diagnosis system has detected a
malfunction or abnormality in the system.
DIAGNOSTIC TROUBLE CODE CHECK
1. Turn ignition switch ON.
2. Using SST, connect terminals between TE1 and E1 of data
link connector 1 or 2.
SST 09843±18020
3. Read the diagnostic trouble code from malfunction indicator
lamp.
HINT: If a diagnostic trouble code is not output, check the TE1
terminal circuit (See page EG±484).
As an example, the blinking patterns for codes; normal, 12
and 31 are as shown on the illustration.
4. Check the details of the malfunction using the diagnostic
trouble code table on page EG±388.
5. After completing the check, disconnect terminals TE1 and
E1, and turn off the display.
HINT: In the event of 2 or more malfunction codes, indication
will begin from the smaller numbered code and continue in
order to the larger.
