ENGINE TUNE-UP [FS]

A3U011002000W04

Engine Tune-up Preparation

1. Warm up the engine to normal operating temperature.
2. Shift the transaxle into neutral.
3. Turn off all electrical loads.

•

Headlight switch

•

Fan switch

•

Rear window defroster switch

•

A/C switch

4. Verify that the steering wheel is at straight ahead position.
5. Connect the SSTs (WDS or equivalent) to the 

DLC-2.

6. Access RPM PID.
7. Wait until the electrical fan stops.

Ignition Timing Inspection

1. Perform “Engine Tune-up Preparation”.
2. Verify that the RPM PID is within the specification.

•

If not as specified, adjust the idle speed. (See 01–10B–26 Idle Speed Adjustment.)

Specification

650—750 (700

±±±±

50) rpm

3. Connect the timing light to the high-tension lead of the No.1 cylinder.
4. Verify that the timing mark (yellow) on the crankshaft pulley is within the specification.

•

If not as specified, inspect following.
— CMP sensor
— CKP sensor
— TP sensor
— ECT sensor
— Neutral switch (MTX)
— Clutch switch (MTX)
— TR switch (ATX)

•

If the devices are normal, replace the PCM. (See 01–40B–7 PCM REMOVAL/INSTALLATION [FS].)

Caution

••••

The TAS is set at the factory and must 
not be adjusted. Any adjustment will 
negatively effect the engine performance.

3. Connect the SST (System selector) to the DLC.
4. Set switch A to position 1.
5. Set the test switch to SELF TEST.
6. Press CLEAR to clear previously selected items.
7. Disconnect the SSTs.

Idle-up Speed Inspection

1. Perform “Engine Tune-up Preparation”.
2. Connect the SST (System selector) to the DLC.
3. Set switch A to position 1.
4. Set the test switch to SELF TEST.
5. Verify that the idle speed is normal. (See 01–10B–26 Idle Speed Adjustment.)
6. Verify that the RPM PID is within the specification.

•

If not as specified with all load conditions, inspect the IAC valve.

•

If not as specified with some load condition, inspect the related input switches, harnesses, and connectors.
