Without Scan Tool

HINT:
- By switching from normal mode into test mode, you can inspect the stop lamp switch and the RH and LH front wheel speed sensors.

- When entering the test mode, the stabilizer control ECU sets all the test DTCs first.

After completing the input signal operation for each inspection item, the DTCs that are determined to be normal by the stabilizer control ECU will be erased.

The DTCs for other inspection items may not be erased when only a certain signal is inspected.

- When the test mode returns back to the normal mode, all the test DTCs will be erased.

TEST MODE (USING SST CHECK WIRE)

a. Procedure for Test Mode.




1. Make sure that the ignition switch is off.
2. Set each of the check items to the condition in Operation (A) in the test mode table.




3. Using SST, connect terminals TS and CG of the DLC3.

4. Turn the ignition switch to the ON position.




5. Check that the KDSS indicator lamp blinks.

HINT:
- At this time, the KDSS indicator lamp should come on for 2 seconds. After that, it blinks at 0.25 second intervals.
- If the KDSS indicator lamp does not blink, inspect the KDSS indicator lamp circuit or the TS terminal circuit.

TS terminal circuit




6. Set each of the check items to the condition in Operation (B) in the test mode table.

HINT:
- In step (6), all signals can be checked together.
- When checking each item, the KDSS indicator lamp should come on for 1 second then continue blinking.

7. Vehicle is stopped.




8. Connect the 3rd terminal of the SST to terminal TC of the DLC3.

9. Read the number of blinks of the KDSS indicator lamp.

HINT:
- As an example, the blinking patterns of a normal system code and trouble code 82 are shown.
- If 2 or more malfunctions are indicated at the same time, the lowest numbered code is displayed first.
- When a DTC or normal system code is not output, check the TC terminal circuit.

10. Check the malfunction using the code table.

C1782 - C1795:

DTC of KDSS test mode function:
If a trouble code is displayed during the test mode DTC check, check the circuit listed for that code. For details of each code, refer to the respective "DTC No." in the chart.`

b. Ending the Test Mode.
1. Turn the ignition switch off.
2. Disconnect the SST from the terminals of the DLC3.
