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.
