Wiring Diagram
| [A]: | A/T vehicle | 1. | VSS | 3. | ECM |
| [B]: | M/T vehicle | 2. | To main relay | 4. | Combination meter |
DTC Detecting Condition and Trouble Area
| DTC detecting condition | Trouble area |
|---|---|
|
•
Vehicle speed signal is not input while fuel cut at deceleration for 4 seconds continuously at 4000 rpm or less.
(2 driving cycle detection logic)
• Vehicle speed signal is not input even if engine running with more than 3600 rpm at D-Range for 4 sec. |
•
“BLK/ORN” circuit open
• “YEL/GRN” or “BLU/BLK” circuit open or short • VSS malfunction • Combination meter malfunction • ECM malfunction |
DTC Confirmation Procedure
WARNING:
•
When performing a road test, select a place where there is no traffic or possibility of a traffic accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and a tester.
• Road test should be carried out with 2 persons, a driver and a tester.
1)
With ignition switch turned OFF, connect scan tool.
2)
Turn ON ignition switch and clear DTC using scan tool.
3)
Warm up engine to normal operating temperature.
4)
Drive vehicle at 3000 rpm (engine speed) with 5th gear or D-range.
5)
Release accelerator pedal and with engine brake applied, keep vehicle coasting for 6 sec. or more (fuel cut condition for 5 sec. or more) and stop vehicle.
6)
For A/T vehicle, drive vehicle at more than 3600 rpm for 10 sec.
7)
Check pending DTC and DTC.
DTC Troubleshooting
| Step | Action | YES | NO |
|---|---|---|---|
| 1 |
Was “Engine and Emission Control System Check” performed?
|
Go to Step 2.
|
|
| 2 |
Vehicle speed signal check
Is vehicle speed displayed on scan tool in Step 4) and 5) of “DTC Confirmation Procedure”?
|
Intermittent trouble. Check for intermittent referring to
Intermittent and Poor Connection Inspection
.
|
Go to Step 3.
|
| 3 |
Power supply circuit check
1)
With ignition switch turned OFF, disconnect connector from VSS.
2)
Check for proper connection to “BLU/BLK”, “YEL/GRN” and “BLK/ORN” wire terminals of VSS connector.
3)
If wires are OK, turn ON ignition switch, measure voltage between vehicle body ground and “BLU/BLK” wire terminal of VSS connector.
Is it voltage 10 – 14 V?
|
Go to Step 4.
|
“BLU/BLK” wire open circuit.
|
| 4 |
Ground circuit check
1)
Measure resistance between vehicle body ground and “BLK/ORN” wire terminal of VSS connector with ignition switch turn OFF.
Is resistance below 5 Ω?
|
Go to Step 5.
|
“BLK/ORN” wire open or high resistance circuit.
|
| 5 |
Wire circuit check
1)
Turn ON ignition switch, measure voltage between vehicle body ground and “YEL/ GRN” wire terminal at VSS connector.
Is it voltage 4 – 5 V?
|
Go to Step 10.
|
Go to Step 6.
|
| 6 |
Wire circuit check
1)
Turn OFF ignition switch.
2)
Disconnect connectors from combination meter.
3)
Check for proper connection to “YEL/GRN” wire terminal of combination meter connector.
4)
Turn ON ignition switch, measure voltage between vehicle body ground and “YEL/GRN” wire terminal of VSS connector.
Is it voltage 10 – 12 V?
|
Substitute a known-good combination meter and recheck.
|
Go to Step 7.
|
| 7 |
ECM voltage check
1)
Turn ON ignition switch, measure voltage between vehicle body ground and “E119-19” terminal at ECM connector.
Is it voltage 4 – 5 V?
|
“YEL/GRN” wire open circuit.
|
Go to Step 8.
|
| 8 |
Short circuit check
1)
Disconnect connectors from ECM with ignition switch turned OFF.
2)
Turn ON ignition switch, measure voltage between vehicle body ground and “E119-19” terminal of ECM connector.
Is it voltage 0 V?
|
Go to Step 9.
|
“YEL/GRN” wire shorted to power supply circuit.
|
| 9 |
Short circuit check
1)
Measure resistance between vehicle body ground and “E119-19” terminal of ECM connector with ignition switch turned OFF.
Is resistance infinity?
|
Go to Step 10.
|
“YEL/GRN” wire shorted to ground circuit. If wire are OK, substitute a known-good ECM and recheck.
|
| 10 |
VSS check
1)
Check VSS and signal rotor tooth referring to
Vehicle Speed Sensor (VSS) Inspection:M13A
.
Is check result satisfactory?
|
Substitute a known-good ECM and recheck.
|
Replace VSS or signal rotor.
|
NOTE:
Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and confirm that the trouble has been corrected.
