CRUISE CONTROL: DYNAMIC RADAR CRUISE CONTROL SYSTEM: TERMINALS OF ECU

1. CHECK DISTANCE CONTROL ECU









(a) Reference: waveform 1





HINT
* Terminal: LRDD - SGND
* Gauge set: 2 V/DIV., 10 msec./DIV.
* Condition: Engine switch on (IG)

(b) Reference: waveform 2





HINT
* Terminal: LRRD - SGND
* Gauge set: 2 V/DIV., 5 msec./DIV.
* Condition: Engine switch on (IG)

2. CHECK ECM (for 1UR-FSE)









If the value is not within the standard range, the ECM may have a malfunction.

3. CHECK ECM (for 2GR-FSE)









If the value is not within the standard range, the ECM may have a malfunction.

4. CHECK MILLIMETER WAVE RADAR SENSOR
