− − − − Multiplex Sleep Mode Test Multiplex Wake-up Mode Test Operation Method used for wake up 22-192 Multiplex Control System Troubleshooting (cont’d) 1. Connect the positive lead of a voltmeter to terminal No. 10 of the under-dash fuse/relay box connector 2. Connect an ammeter between the negative battery cable and the negative battery post. 3. Remove the special tool from the multiplex inspection connector. 4. Close the doors, the hatch, turn the headlights off, turn the ignition switch OFF and remove the key. 5. Within 1 minute, the voltage on the communication wire (E10 or K10) should change from about 10 V to battery voltage and the amperage at the negative battery terminal should drop from about 80 mA to less than 10 mA. 6. Record your findings and go to the Multiplex Wake- up Mode Test. 1. From the Sleep Mode, wake-up the multiplex system by performing one of the following Cycle ignition All multiplex units wake up Turn Multiplex control unit wakes Open the Multiplex control unit wakes 2. As the system shifts to its Wake-up (Active) Mode, communication wire voltage will return to 4 10 V and the battery terminal current will return to 80 mA. 3. If the system does not go into Sleep Mode or Wake- up Mode properly, perform the Multiplex Control NOTE: If multiple circuits fail to respond in the 05/06/27 18:06:13 61S6M040_220_0193 |
