ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION
Revision: November 2006
2006 Altima
Malfunction Indicator Lamp (MIL)
ECS00963
1.
The malfunction indicator lamp will light up when the ignition
switch is turned ON without the engine running. This is for
checking the lamp.
●
If the malfunction indicator lamp does not light up, refer to
(Or see
EC-66, "Malfunction Indicator Lamp (MIL)"
2.
When the engine is started, the malfunction indicator lamp
should go off.
If the lamp remains on, the on board diagnostic system has
detected an emission-related (OBD-II) malfunction. For details,
refer to ! Hyper-link Error ! .
CONSULT-II Function (TCM)
ECS00964
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
After performing “SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)” (
), place check marks for results on the “Diagnostic Worksheet”,
. Reference pages are provide following the items.
NOTICE:
1.
The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2.
Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
–
Actual shift schedule has more or less tolerance or allowance,
–
Shift schedule indicated in Service Manual refers to the point where shifts start, and
–
Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3.
Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).
4.
Additional CONSULT-II information can be found in the Operation Manual supplied with the CONSULT-II
unit.
SAT964I
TCM diagnostic mode
Description
WORK SUPPORT
Supports inspections and adjustments. Commands are transmitted to the TCM for setting the status
suitable for required operation, input/output signals are received from the TCM and received data is
displayed.
SELF-DIAG RESULTS
Displays TCM self-diagnosis results.
DATA MONITOR
Displays TCM input/output data in real time.
CAN DIAG SUPPORT MNTR
The result of transmit/receive diagnosis of CAN communication can be read.
ACTIVE TEST
Operation of electrical loads can be checked by sending drive signal to them.
FUNCTION TEST
Conducted by CONSULT-II instead of a technician to determine whether each system is "OK" or "NG".
ECU PART NUMBER
TCM part number can be read.
