Communication
Description
The skid control ecu sends signals such as cruise control cancel demand
signals and brake operation
demand from ecm response signals to the ecm when the cruise control system is in
operation.
Inspection procedure
Hint:
This circuit uses can communication. Therefore, if t ...
Diagnosis system
Description
When troubleshooting obd ii (on-board diagnostics)
vehicles, the intelligent tester (complying with sae
j1987) must be connected to the dlc3 (data link
connector 3) of the vehicle. Various data in the vehicle's
ecm (engine control module) can be then read.
