Test Mode Check (Using SST Check Wire)
TEST MODE CHECK (USING SST CHECK WIRE)HINT:
- When entering the test mode, the suspension control ECU sets all the test DTCs first.
After completing the input signal operation for each inspection item, the DTCs that are judged normal by the suspension 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.
a. Procedure for Test Mode.
1. Make sure that the ignition switch is off.
2. Set each of the check items in the table given to the condition in Operation (A).
3. Using the SST(s), connect the terminals TS and CG of DLC3.

4. Turn the ignition switch to the ON position.
5. Check that the height control OFF indicator lamp comes on and goes off at 0.125 second intervals.(4 Hz)
HINT: If the height control OFF indicator lamp does not blink, inspect the height control OFF indicator lamp circuit or the TS terminal circuit.
Trouble Area
Height control OFF indicator lamp circuit
TS terminal circuit
6. Set each of the check items to the condition in Operation(B).
HINT:
- When checking each item, the height control OFF indicator lamp should come on for 1 sec. then continue blinking.
- There is no input signal order.
7. Using the SST(s), connect the 3rd terminal of the SST to terminal TC in the DLC3.

8. Read the number of blinks of the height control OFF indicator lamp.
HINT:
- As an example, the blinking patterns of a normal code and code 82 are shown in the illustration.
- If 2 or more malfunctions are indicated at the same time, the lowest numbered code is displayed first.
- When a DTC or normal code is not output, check the TC terminal circuit.
9. Check the malfunction using the code table.
b. Clear the test DTCs and return to normal mode.
HINT: After repairing the malfunctions, clear the test DTC.
1. Turn the ignition switch off.
2. Disconnect the SST(s) from the terminals of DLC3.
