Nissan Almera Tino V10. Instruction — part 429
EC-542
[QG (WITH EURO-OBD)]
ELECTRICAL LOAD SIGNAL
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic Procedure
EBS00QTV
1.
CHECK LOAD SIGNAL CIRCUIT OVERALL FUNCTION-I
With CONSULT-II
With GST
1.
Turn ignition switch “ON”.
2.
Connect CONSULT-II or GST and select “DATA MONITOR” mode.
3.
Select “LOAD SIGNAL” and check indication under the following
conditions.
OK or NG
OK (With CONSULT-II)>>GO TO 2.
OK (Without CONSULT-II)>>GO TO 3.
NG
>> GO TO 4.
2.
CHECK LOAD SIGNAL CIRCUIT OVERALL FUNCTION-II
With CONSULT-II
Check “LOAD SIGNAL” indication under the following conditions.
OK or NG
OK
>> INSPECTION END
NG
>> GO TO 5.

CHECK LOAD SIGNAL CIRCUIT OVERALL FUNCTION-II
Without CONSULT-II
Check voltage between ECM terminal 84 and ground under the fol-
lowing conditions.
OK or NG
OK
>> INSPECTION END
NG
>> GO TO 5.
4.
CHECK REAR WINDOW DEFOGGER SYSTEM
Refer to “REAR WINDOW DEFOGGER”, EL-177.
>> INSPECTION END
5.
CHECK HEADLAMP FUNCTION
1.
Turn lighting switch “ON” at 2nd position.
2.
Check that headlamps are illuminated.
OK or NG
OK
>> GO TO 6.
NG
>> Refer to “HEADLAMP-DAYTIME LIGHT SYSTEM-”, EL-45 or “HEADLAMP-HEADLAMP AIMING
CONTROL-”, EL-52.
6.
CHECK HEADLAMP INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
WITHOUT DAYTIME LIGHT SYSTEM
1.
Turn ignition switch “OFF”.
2.
Disconnect ECM harness connector.
3.
Disconnect combination switch (lighting switch) harness connector.
4.
Check harness continuity between ECM terminal 84 and combination switch (lighting switch) terminal 10.
Refer to Wiring Diagram.
5.
Also check harness for short to ground and short to power.
WITH DAYTIME LIGHT SYSTEM
1.
Turn ignition switch “OFF”.
2.
Disconnect ECM harness connector.
3.
Disconnect headlamp relay.
4.
Check harness continuity between ECM terminal 84 and headlamp relay terminal 7.
Refer to Wiring Diagram.
5.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 8.
NG
>> GO TO 7.

DETECT MALFUNCTIONING PART
Check the following.
●
Harness connectors E105, M10 (LHD models)
●
Harness connectors E145, M80 (RHD models)
●
harness for open and short between ECM and combination switch (lighting switch)
●
