6 | Auto-cruise control-ECU power supply | Ignition switch: ON | System voltage
7 | Auto-cruise vacuum pump release valve | When decelerating with the auto-cruise control SET switch while driving at constant speed | 1 V or less
8 | Auto-cruise vacuum pump control valve | 10 V or more
7 | Auto-cruise vacuum pump release valve | When cancelling constant speed driving with the auto-cruise control CANCEL switch | 10 V or more
8 | Auto-cruise vacuum pump control valve | System voltage
9 | Auto-cruise control switch input | MAIN switch: ON | Approximately 7.0 V
When input switch has not been operated | All switches: OFF | 3.5 - 5.0 V
When input switch is pushed down | SET switch: ON | 0.4 - 2.3 V
When input switch is pushed up | RESUME switch: ON | 2.3 - 3.5 V
When input switch is pulled forward | CANCEL switch: ON | 0.4 V or less
10 | Vehicle speed signal input | When vehicle is moved forwards and backwards, signal turns ON and OFF repeatedly | When signal is ON | 0 V
When signal is OFF | 8 - 12 V*
12 | Auto-cruise control-ECU power supply | Ignition switch: ON MAIN switch: ON | System voltage
13 | Inhibitor switch input | Select lever: Other than N or P range | System voltage
Select lever: N or P range | 0 V
14 | Earth | At any time | 0 V
15 | Auto-cruise control indicator lamp input | MAIN switch: ON (When indicator lamp is illuminated) | 0 V
MAIN switch: OFF (When indicator lamp is switch off) | System voltage
16 | Auto-cruise vacuum pump motor input | When driving at constant speed using the SET switch | Motor stopped/running | System voltage/0 V
When accelerating with the RESUME switch while driving at constant speed | Motor stopped/running | System voltage/0 V
When decelerating with the SET switch while driving at constant speed | Motor stopped | System voltage
When cancelling constant speed driving with the CANCEL switch | Motor stopped | System voltage
NOTE: *: Auto-cruise control-ECU terminal No.10 is sending a voltage of 5 volts to the vehicle speed signal system circuit. However, as higher voltage is mixed through the circuit a voltmeter will show 8 - 12 V.
