Basic Inspection

Basic Inspection

1. INSPECTION START

1 Check service records for any recent repairs that may indicate a related malfunction, or a current need for scheduled maintenance.
2 Open engine hood and check the following:





- Harness connectors for improper connections
- Wiring harness for improper connections, pinches and cut
- Vacuum hoses for splits, kinks and improper connections
- Hoses and ducts for leakage
- Air cleaner clogging
- Gasket
1 Check that electrical or mechanical loads are not applied.
- Headlamp switch is OFF.
- Air conditioner switch is OFF.
- Steering wheel is in the straight-ahead position, etc.
1 Start engine and warm it up until engine coolant temperature indicator points to the middle of gauge.





Ensure engine stays below 1,000 rpm.
2 Run engine at about 2,000 rpm for about 2 minutes under no load.





3 Make sure that no DTC is displayed with SDT or GST.

2. REPAIR OR REPLACE

Repair or replace components as necessary according to corresponding Diagnostic Procedure.


GO TO 3.

3. CHECK TARGET IDLE SPEED

With SDT
1 Run engine at about 2,000 rpm for about 2 minutes under no load.
2 Rev engine (2,000 to 3,000 rpm) two or three times under no load, then run engine at idle speed for about 1 minute.





3 Read idle speed in "Data list" mode with SDT. Refer to [Idle Speed and Ignition Timing Check] Idle Speed and Ignition Timing Check.






Without SDT
1 Run engine at about 2,000 rpm for about 2 minutes under no load.
2 Rev engine (2,000 to 3,000 rpm) two or three times under no load, then run engine at idle speed for about 1 minute.
3 Check idle speed. Refer to [Idle Speed and Ignition Timing Check] Idle Speed and Ignition Timing Check.

OK or NG
OK
GO TO 9.

1 Repair or replace.
2 GO TO 4.

9. CHECK ECM FUNCTION

1 Substitute with a non-malfunctioning ECM to check ECM function. (ECM may be the cause of the incident, although this is rare.)
2 Perform initialization of immobilizer system and registration of all immobilizer system ignition key IDs. Refer to [Procedure After Replacing ECM] Testing and Inspection.


GO TO 4.

10. CHECK IGNITION TIMING

1 Run engine at idle.
2 Check ignition timing with a timing light. Refer to [Idle Speed and Ignition Timing Check] Idle Speed and Ignition Timing Check.











OK or NG
OK
GO TO 19.
NG
GO TO 11.

11. PERFORM ACCELERATOR PEDAL RELEASED POSITION LEARNING
