TROUBLE CODE DISPLAY IN NORMAL MODE^ TO OBTAIN AN OUTPUT OF DIAGNOSTIC TROUBLE CODES, PROCEED AS FOLLOWS:
1. Initial conditions
- Battery voltage 11 Volts or more
- Throttle valve fully closed
- Throttle position sensor IDL points closed.
- Transmission in neutral position
- Accessories switched OFF
- Engine at normal operating temperature
2. Turn the ignition switch ON.
NOTE: DO NOT start the engine.
3. Using a jumper wire, connect terminals TE1 and E1 of the DLC1.
Malfunction Indicator Light:
4. Read the diagnostic trouble code as indicated by the number of flashes of the MIL.
- Refer to "Trouble Code Descriptions" for an explanation of output codes.
Diagnostic Trouble Code Descriptions
HINT: In the event of a number of trouble codes, indication will begin from the smaller value and continue to the larger.
5. After the diagnosis check, remove the jumper from the DLC1.
TROUBLE CODE DISPLAY IN TEST MODE
NOTES:
- Compared to the normal mode, the test mode has an increased sensing ability to detect malfunctions.
- It can also detect malfunctions in the starter signal circuit, air conditioning signal and PNP switch signal.
- Furthermore, the same diagnostic items which are detected in the normal mode can also be detected in the test mode.
^ To obtain an output of diagnostic trouble codes, proceed as follows:
1. Initial conditions.
- Battery voltage 11 Volts or more.
- Throttle valve fully closed
- Throttle position sensor IDL points closed.
- Transmission in neutral position
- Accessories switched OFF.
2. Turn the ignition switch OFF.
3. First, using a jumper wire (or SST 09843-18020), connect terminals TE2 and E1 of the DLC1.
HINT:The test mode will not start if terminals TE2 and E1 are connected after the ignition switch is turned ON.
4. Turn the ignition switch ON.
HINT: To confirm that the test mode is operating, check that the MIL flashes when the ignition switch is turned ON.
5. Start the engine and drive the vehicle at a speed of 10 km/h (6 mph) or higher.
6. Simulate the conditions of the malfunction described by the customer.
"Test" Mode Is Enabled By Connecting TE2 To E1:
7. Using a jumper wire, connect terminals TE1 and E1 of the DLC1.
8. Read the diagnostic trouble code as indicated by the number of flashes of the MIL.
- Refer to "Trouble Code Descriptions" for an explanation of output codes.
Diagnostic Trouble Code Descriptions
HINT: In the event of a number of trouble codes, indication will begin from the smaller value and continue to the larger.
9. After the diagnosis check, remove the jumper wire from the DLC1.
NOTES:
- The starter signal and vehicle speed signal will be diagnosed by the ECM as malfunctions, and code Nos.42, and 43 will be output, if the operation in step 4 is not done.
- When the automatic transmission 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. This is normal system operation.
