Engine Control System (4JH1) 6E-31
Diagnostic Starting Point - Engine Controls
Begin the system diagnosis with Diagnostic System
Check - Engine Controls. The Diagnostic System Check
- Engine 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 - Engine
Controls will identify the correct procedure fo
r
diagnosing the system and where the procedure is
located.
Important:
Engine Control System Check Sheet must be used to
verify the complaint vehicle, you need to know the
correct (normal) operating behavior of the system and
verify that the customer complaint is a valid failure o
f
the system.
Reading Flash Diagnostic Trouble Codes
The provision for communicating with the ECM is the
Data Link Connector (DLC). The DTCs stored in the
ECM memory can be read either through a hand-held
diagnostic scanner such as scan tool plugged into the
DLC or by counting the number of flashes of the MIL
when the diagnostic test terminal of the DLC is
grounded. The DLC terminal “6” (diagnostic request
switch) is pulled “Low” (grounded) by jumped to DLC
terminal “4”, which is a ground wire.
Once terminals “4” and “6” have been connected, the
ignition switch must be moved to the “ON” position, with
the engine not running. The MIL will initially flash 12.
Then, the MIL will flash the first stored DTC three times,
second stored DTC three times and so on. All the
stored DTCs are flashed, then return 12 and continue to
flash the DTC. If no DTC exists, the MIL flashes 12
continuously. The flash DTC display will continue as
long as the DLC is shorted.
