Input Signal Check (Test Mode Check)
CHECK INPUT SIGNALThis function checks if signals from the steering sensor and stop light switch are being input normally to the ECU.
1. Turn ignition switch on.
2. Set each of the check items in the image to the condition in Operation (A).
3. Using SST, connect terminals Ts and E1 of the check connector.
SST 09843-18020
HINT: At this time the height control indicator "NORM" light flashes at 0-25 second intervals while the engine is stopped and stays on when the engine is running. (It indicates that the system has entered the input signal check mode.)
4. Check if the height control indicator "NORM" light lights up when each of the individual check items is set to the condition in Operation (B).
*1: "A" and "B" under "Engine Condition" indicate the condition of the height control indicator "NORM" light when the check results are normal (when signals are being sent normally to the ECU). "A" means that the light blinks every 0.25 seconds and "8" means that it remains lit.
HINT:
- During operation of this check, damping force and spring rate control are stopped, and the damping force and spring rate are both fixed to the "firm". Vehicle height control continues to operate normally
- During operation of this check, if terminals Ts and E1 of the check connector inside the engine compartment are connected, the diagnostic codes stored in memory are output. If no diagnostic code is stored in memory, the input signal check function operates.
