DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn ignition switch on.
• With the scan tool, record and erase stored DTCs in the ECM.
• Start engine and warm it to normal operating temperature, then select view DTC and data stream.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-

Downloaded from www.Manualslib.com manuals search engine Low Idle / Stalls During Deceleration
The following conditions apply to this symptom:
•Engine stops unexpectedly at beginning of deceleration or recovery from deceleration.
1.PRELIMINARY CHECKS
• Carry out the following preliminary checks:
Vacuum lines (routing, leaks)
Intake air tubes
Wiring connections
Are all checks OK?
Ye s>>Go to the next step.
No
>>Repair as necessary.
Verify the symptom no longer exists.
2.CHECK FOR ROUGH OR STALL AT IDLE
• Check for rough idle or stall at idle.
NOTE :
Confirm that proper vehicle maintenance has been performed before continuing with engine diagnosis.
• Inspect the following components:
Clean the carbon deposit on intake and exhaust valves
Valve stem
Spark plugs and combustion chamber
Does the engine idle rough?
Ye s>>Repair as necessary.
No
>>Go to the next step.
3.CHECK ECM DTC
• Turn the ignition switch on.
• With the scan tool X-431, read the DTC.
Are there any DTCs present?
Ye s>>Repair as necessary.
No
>>Go to the next step.
4.CHECK THE ELECTRONIC THROTTLE CONTROL (ETC) ACTUATOR
• Start engine and let idle.
• Disconnect ETC actuator connector and check for RPM drop or engine stall.
Did RPM drop or engine stall when the ETC connector was disconnected?
Ye s>>Connect ETC actuator connector.
Go to the next step.
No
>>Repair as necessary.
