TRANSMISSION CONTROL SYSTEM (AW30–40LE) 7A2-53

• No L-up solenoid functional failure detection.
• Check Trans “ON”.
• DTC stored.
• MIL request “ON”. (EURO 4 only)
Conditions For Clearing The DTC
• The DTC can be cleared from the TCM history by
using a scan tool.
• The DTC will be cleared from history when the
vehicle has achieved 40 warm-up cycles without a
failure reported.
•
After more than 1 second has elapsed after the
ignition key has been turned “ON”, short between
No.11 and No.4 (ground) of DLC (Data Link
Connector). Then, after 1 second, but within 6
seconds, discontinue shorting.
Diagnostic Aids
•
Inspect the wiring for poor electrical connection at the
TCM. Look for possible bent, backed out, deformed
or damaged terminals. Check for weak terminal
tension as well. Also check for a chafed wire that
could short to bare metal or other wiring. Inspect for a
broken wire inside the insulation.
• W hen diagnosing for a possible intermittent short o
r
open condition, move the wiring harness while
observing test equipment for a change.
• Check oil temperature sensor for proper mounting
and adjustment.

TRANSMISSION CONTROL SYSTEM (JR405E) 7A2-21
Diagnostic Information and Procedures
Diagnostic Starting Point - Transmission Controls
Begin the system diagnosis with Diagnostic System
Check - Transmission Controls. The Diagnostic System
Check - Transmission Controls will provide the
following information:
• The identification of the control modules which command the system.
• The ability of the control modules to communicate through the serial data circuit.
• The identification of any stored diagnostic trouble codes (DTCs) and the their statuses.
The use of the Diagnostic System Check -
Transmission Controls will identify the correct
procedure for diagnosing the system and where the
procedure is located. Reading Flash Diagnostic Trouble Codes (DTC)
The provision for communicating with the TCM is the
Data Link Connector (DLC). The DTC(s) stored in the
TCM memory can be read either through a hand-held
diagnostic scanner such as Tech 2 plugged into the
DLC or by counting the number of flashes of the
CHECK TRANS lamp when the diagnostic test terminal
of the DLC is grounded. The DLC terminal “11”
(diagnostic request) is pulled “Low” (grounded) by
jumped to DLC terminal “4”, which is a ground wire.
Once terminals “11” and “4” have been connected, turn
the ignition switch ON, with the engine OFF. The
CHECK TRANS lamp initially flashes 12. If more than
one DTC has been stored in the TCM's memory, the
DTCs will be output numerical order with each DTC
being displayed three times. All the stored DTCs are
flashed, then return 12 and continue to flash the DTC. If
no DTC exists, the CHECK TRANS flashes 12
continuously. The flash DTC display will continue as
long as the DLC is shorted.
Diagnostic Trouble Codes (DTC) Clear Method
If there is no scan tool, history DTCs can be cleared by
removing the ECM (B) (10A) fuse for at least 10
seconds with the ignition switch OFF.
