TROUBLE CODE DIAGNOSIS - GASOLINE VEHICLE
TCM DIAGNOSTIC SYSTEM
OVERVIEW
Notice: To prevent Transmission Control Module (TCM)
damage. The ignition key must be OFF when
disconnection or reconnection the power to the TCM
(for example bttery cable, TCM pigtail connector, TCM
fuse, jumper cables, etc.).
When the TCM detects a system fault, a Diagnostic
Trouble Code (DTC) is set in the TCM. This code is
present while the fault conditions are met and is stored
as a ‘History DTC’ until cleared. Condition for setting
and clearing each TCM DTC are provided in the relevant
sections.
In the case where the vehicle type is certified for Eure
On-Board Diagnostic (EOBD) compliance, the Engine
Control Module (ECM) provides the communication linkto the EOBD scan tool to pass on any EOBD relevant
codes from the TCM. The table below contains a list of
all supported DTCs and the classification of each for
EOBD purposes. Where a type B DTC has been set in
an EOBD vehicle, the response to the fault may include
action by the ECM, including the illumination of the
Malfunction lndicator Lamp (MIL). Refer to Section 1F,
Engine Control, for details on EOBD system function,
checks and fault clearing.
CLEARING TROUBLE CODES
TCM DTCs should be cleared after repairs have been
completed. Some diagnostic tables will tell you to clear
the codes before using the chart, which will help to
find the cause of the problem more quickly. Always
note the DTCs present before clearing - this information
may be helpful in the diagnostic process.”

DIAGNOSTIC TROUBLE CODES (Cont'd)
DTC Types
Each DTC is directly related to a diagnostic test. The
Diagnostic management system sets DTCs based on
the failure of the tests during a driving cycle or cycles.
The following are the two types of DTCs and the charac-
teristics of those codes;
Type B
Emissions related.
EOBD system “Armed” after one driving cycle with
a fail.
EOBD system “Disarmed” after one driving cycle
with a pass.
Illuminates the MIL on the second con-secutive
driving cycle with a fail.
TCM stores a history DTC on the first driving cycle
with a fail.
EOBD system stores a history DTC on the second
consecutive driving cycle with a fail, (the DTC will
be armed after the first fail).
EOBD system stores a freeze frame on the second
consecutive driving cycle with a fail, (if empty).
Type D
Non-Emissions related.
Does not request illumination of any lamp.
Stores a history DTC on the first driving cycle with
a fail.
EOBD system does not store a freeze frame. DTC
