DIAGNOSIS SYSTEM
1. DESCRIPTION
(a) When troubleshooting On-Board Diagnostic (OBD
II) vehicles, the vehicle must be connected to the
OBD II scan tool (complying with SAE J1987).
Various data output from the vehicle's ECM can
then be read.
(b) OBD II regulations require that the vehicle's on-
board computer illuminates the Malfunction
Indicator Lamp (MIL) on the instrument panel when
the computer detects a malfunction in:
(1) The emission control system/components
(2) The powertrain control components (which affect
vehicle emissions)
(3) The computer
In addition, the applicable Diagnostic Trouble
Codes (DTCs) prescribed by SAE J2012 are
recorded in the ECM memory.
When the malfunction does not reoccur, the MIL
stays illuminated until the ignition switch is
turned OFF, and the MIL turns OFF when the
engine is started. However, the DTCs remain
recorded in the ECM memory.
(c) To check DTCs, connect the intelligent tester to the
Data Link Connector 3 (DLC3) of the vehicle. The
tester displays DTCs, the freeze frame data and a
variety of the engine data.
The DTCs and freeze frame data can be erased
with the tester (see page AX-29).
2. NORMAL MODE AND CHECK MODE
(a) The diagnosis system operates in "normal mode"
during normal vehicle use. In normal mode, "2 trip
detection logic" is used to ensure accurate detection
of malfunctions. "Check mode" is also available to
technicians as an option. In check mode, "1 trip
detection logic" is used for simulating malfunction
symptoms and increasing the system's ability to
detect malfunctions, including intermittent
malfunctions.
3. 2 TRIP DETECTION LOGIC
(a) When a malfunction is first detected, the
malfunction is temporarily stored in the ECM
memory (1st trip). If the same malfunction is
detected during the next drive cycle, the MIL is
illuminated (2nd trip).
