1. DIAGNOSIS SYSTEM
(a) Description
When troubleshooting OBDII vehicles, the only dif-
ference from the usual troubleshooting procedure
is that you connect to the vehicle the OBDII scan
tool complying with SAE J1978 or TOYOTA hand−
held tester, and read off various data output from
the vehicle’s ECM.
OBDII regulations require that the vehicle’s on−
board computer lights up the Malfunction Indicator
Light (MIL) on the instrument panel when the com-
puter detects a malfunction in the computer itself on
in drive system components which affect vehicle
emissions. In addition to the MIL lighting up when
a malfunction is detected, the applicable Diagnostic
Trouble Code (DTC) prescribed by SAE J2012 are
recorded in the ECM memory (See page DI−14).
If the malfunction does not recur in 3 trips, the MIL
goes off but the DTC remain recorded in the ECM
memory.
To check the DTC, connect the OBDII scan tool or
TOYOTA hand−held tester to Data Link Connector
3 (DLC3) on the vehicle. The OBDII scan tool or
TOYOTA hand−held tester also enables you to
erase the DTC and check freezed frame data and
various forms of engine data. (For operating instruc-
tions, see the OBDII scan tool’s instruction book.)
DTC include SAE controlled codes and Manufac-
ture controlled codes.
SAE controlled codes must be set as prescribed by
the SAE, while Manufacturer controlled codes can
be set freely by the manufacturer within the pre-
scribed limits (See DTC chart on page DI−14).
The diagnosis system operates in normal mode
during normal vehicle use. It also has a check mode
for technicians to simulate malfunction symptoms
and troubleshoot. Most DTC use 2 trip detection
logic* to prevent erroneous detection and ensure
thorough malfunction detection.
