With Scan Tool





When using the scan tool (MUT-II)
1. Connect the scan tool to the data link connector 1.

CAUTION: Turn off the ignition switch beforehand whenever the scan tool is connected or disconnected.

2. If the scan tool makes a peep sound when each switch is operated (turned ON/OFF), the input signal to ECU is normally sent from the switch circuit system.
