Confirming Sleep Mode
WARNING: This page is about a different car, the 1998 Honda Prelude. However, it is still accessible from the selected car via links, so may be relevant.
- Check for voltage on driver's and passenger's multiplex control unit wake-up communication line (Brown wire for door-to-driver's control unit; Pink and Light Green wire for driver's-to-passenger's control unit). See WIRING DIAGRAMS .
- If sleep mode is off, voltage on communication line will be zero. If sleep mode is on, voltage (3.5-9.5 volts for door-to-driver's control unit; 4.0-10.5 volts for driver's-to-passenger's control unit; 3-10 volts for passenger's-to-driver's control unit) will be present on communication line. See IDENTIFYING COMMUNICATION LINE & LINE VOLTAGE table.
- Check voltage between each multiplex control unit communication line and ground while shifting to sleep mode. See IDENTIFYING COMMUNICATION LINE & LINE VOLTAGE table. There should be zero volts at each communication line when changing to sleep mode.
- Check parasitic draw at battery while changing to sleep mode. Parasitic draw should change from 70-80 milliamps to less than 10 milliamps.
IDENTIFYING COMMUNICATION LINE & LINE VOLTAGE
| Communication Line (Wire Color) | Voltage |
|---|---|
| Door-To-Driver's (BRN) | 3.5-9.5 |
| Driver's-To-Passenger's (LT GRN) | 4.0-10.5 |
| Passenger's-To-Driver's (PNK) | 3.0-10.0 |
