HOW TO DISPLAY AND READ DIAGNOSTIC TROUBLE CODES WITHOUT A SCAN TOOL

Diagnosis Inspection (Normal Mode)

2. Using SST, connect terminals between TE1 and E1 of the data link connector 1. SST 09843-18020
3. Read the diagnostic trouble code from malfunction indicator lamp.

NOTE: If a diagnostic trouble code is not output, check the TE1 terminal circuit. Component Tests and General Diagnostics

Normal:

Code 12 And 31:

As an example, the blinking patterns for codes; normal, 12 and 31 are shown in the illustrations.

4. Check the details of the malfunction using Trouble Code Descriptions.
5. After completing the check, disconnect the SST from terminals TE1 and E1, and turn off the display.

NOTE: In the event of 2 or more malfunction codes, indication will begin from the smaller numbered code and continue in order to the larger.

Diagnosis Inspection (Test Mode)

Compared to the normal mode, the test mode has high sensability to detect malfunctions.

It can also detect malfunctions in the starter signal circuit, the IDL contact signal of the throttle position sensor, air conditioning signal and park/neutral position switch signal. Furthermore, the same diagnostic items which are detected in the normal mode can also be detected in the test mode.

1. Initial conditions.

(a) Battery positive voltage 11 V or more.
(b) Throttle valve fully closed (throttle position sensor IDL points closed).
(c) Transmission in park/neutral position.
(d) Air conditioning switched OFF.

2. Turn ignition switch OFF.

3. Using SST, connect terminals TE2 and E1 of data link connector 1. SST 09843-18020

4. Turn ignition switch ON.

NOTE:
- To confirm that the test mode is operating, check that the malfunction indicator lamp flashes when the ignition switch turned ON.
- If the malfunction indicator lamp does not flash, refer to diagnostic chart for the TE2 terminal circuit. Component Tests and General Diagnostics

5. Start the engine.
6. Simulate the conditions of the malfunction described by the customer.

7. After the road test, using SST, connect terminals TE1 and E1 of data link connector 1. SST 09843-18020
8. Read the diagnostic trouble code on malfunction indicator lamp in the combination meter.

9. After completing the check, disconnect the SST from terminals TE1, TE2 and E1, and turn off the display.

NOTE:
- The test mode will not start if terminals TE2 and E1 are connected after the ignition switch turned ON.
- When vehicle speed is 3 mph (5 km/h) or below, diagnostic trouble code "42" (Vehicle speed signal) is output, but this is not abnormal.
- When the engine is not cranked, diagnostic trouble code "43" (Starter signal) output, but this is not abnormal.
- When the automatic transaxle shift lever is in the "D", "2", "L" or "R" shift position, or when the air conditioning is on or when the accelerator pedal is depressed, code "51" (Switch condition signal) is output, but this is not abnormal.
