TROUBLE CODE DIAGNOSIS - DIESEL 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.
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."

Circuit Description
The Transmission Control Module (TCM) Diagnistic
System Check is the starting point for any driveability
complaint diagnosis. Before using this procedure,
perform a careful visual/ physical check of the
Transmission Control Module (TCM) and the
transmission grounds for cleanliness and tightness.
The TCM Diagnostic System Check is an organized
approach to identifying a problem created by an
electronic transmission control system malfunction.
TCM DIAGNOSTIC SYSTEM CHECK
Diagnostic Aids
An intermittent fault may be caused by a poor connec-
tion, rubbed-through wire insulation or a wire broken
inside the insulation. Check for poor connections or a
damaged harness. Inspect the TCM harness and con-
nections for improper mating, broken locks, improperly
formed or damaged terminals, poor terminal-to-wire
connection, and damaged harness.

1. Turn the ignition OFF.
2. Disconnect the TCM connector B.
3. Turn the ignition ON.
4. Check the serial data line from TCM connector
terminal A22 to Data Link Connector (DLC)
connector terminal 14 for an open, short to ground,
or short to voltage. Also, check the DLC ignition
feed circuit for an open or short to ground and the
DLC ground circuit for an open.
Is a problem found?
Repair the open, short to ground or short to voltage in
the serial data circuit or the DLC ignition feed circuit
or the DLC ground circuit.
Is a repair complete?
Check the TCM ignition feed circuit for an open or
short to ground and the TCM ground circuit for an
open.
Is a problem found?
Repair the open or short to ground in the TCM ignition
feed circuit or the TCM ground circuit.
Is a repair complete?
1. Turn the ignition OFF.
2. Disconnect the TCM connector.
