DIAGNOSIS SYSTEM
1.
DESCRIPTION
(a)
The transmission control ECU has a self--diagnosis sys-
tem. If the computer, the multi--mode manual transmis-
sion system or the components operate improperly, the
ECU detects a malfunction, and illuminates the multi--
mode manual transmission warning light in the combina-
tion meter.
HINT:
The multi--mode manual transmission warning light illuminates
when the multi--mode manual transmission system malfunc-
tions and blinks when in inspection mode.
(b)
Description for Euro--OBD (European spec.)
S
When troubleshooting Euro--OBD vehicles, the
only difference from the usual troubleshooting pro-
cedure is that the OBD scan tool complying with ISO
15031--4 or the intelligent tester II have to be con-
nected to the vehicle, and various data output from
the vehicle’s ECUs have to be read out.
S
Euro--OBD regulations require that the vehicle’s
on--board computer illuminates the check engine
warning light (MIL) in the combination meter when
the ECU detects a malfunction in: 1) the emission
control systems/components, or 2) the powertrain
control components (which affect vehicle emis-
sions), or 3) the ECU. In addition, the applicable
Diagnostic Trouble Codes (DTCs) prescribed by
ISO 15031--4 are recorded in the transmission con-
trol ECU memory
If the malfunction does not recur in 3 consecutive trips, the MIL
will go off automatically. However, the DTCs remain recorded
in the transmission control ECU memory.
