DATA LIST / ACTIVE TEST
1. DATA LIST/ACTIVE TEST OF AXLE SYSTEM
HINT:
^ By referring to the DATA LIST displayed on the intelligent tester, the value and status of the switch, sensor, ECU, etc. can be read without removing parts. Reading DATA LIST as the first step in troubleshooting is one way to shorten labor time.
^ Performing the ACTIVE TEST using the intelligent tester allows the relay, actuator, etc. to operate without removing parts. Performing the ACTIVE TEST as the first step in troubleshooting is one way to shorten labor time. It is possible to display the DATA LIST during the ACTIVE TEST.
^ The axle system is controlled by the brake control system (skid control ECU) and hybrid control system (HV control ECU). Therefore, the brake control system and hybrid control system can be checked by reading the DATA LIST and performing the ACTIVE TEST.
