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

1. CHECK DISTANCE CONTROL ECU









(a) Reference: waveform 1





HINT
* Terminal: LRDD - GND
* Gauge set: 2 V/DIV, 10 msec./DIV
* Condition: Ignition switch on (IG)
(b) Reference: waveform 2





HINT
* Terminal: LRRD - GND
* Gauge set: 2 V/DIV, 5 msec./DIV
* Condition: Ignition switch on (IG)
2. CHECK ECM









If the value is not within the standard range, some defects on the vehicle are suspected.

HINT
* Terminal: LRDD - SGND
* Gauge set: 1 V/DIV, 2 msec./DIV
* Condition: Ignition switch on (IG)
(b) Reference: waveform 2





HINT
* Terminal: LRRD - SGND
* Gauge set: 1 V/DIV, 2 msec./DIV
* Condition: Ignition switch on (IG)
