Signal Specification
All values specified below are between the relevant terminal and terminal #9 (power ground).
| U= | DC voltage in volts (V) |
| Ubat = | Battery voltage (V) |
| Ulow = | Voltage approximately 0 V |
TABLE OF SIGNALS, 10-PIN CONNECTOR
| Terminal number | Connector marking | Signal type | Ignition off | Ignition on | Other |
|---|---|---|---|---|---|
| #1 | F | - | - | - | - |
| #2 | G | Power supply, occupant weight sensor (OWS) | Ubat for approximately 1 minute after the ignition key is moved to position 0 (applies only if the driver's door and front passenger door are closed). Ubat for approximately 5 minutes (applies if the driver's or front passenger door are opened and left open). Otherwise U low . | U bat | - |
| #3 | H | Signal ground, pressure sensor | U low | U low | - |
| #4 | J | Power supply, pressure sensor | 4.8-5.2 V for approximately 1 minute after the ignition key is moved to position 0 (applies only if the driver's door and front passenger door are closed). 4.8-5.2 V for approximately 5 minutes (applies if the driver's or front passenger door are opened and left open). Otherwise U low . | 4.8-5.2 V | - |
