Connection
| Pin no. | Type of signal | Description |
|---|---|---|
| 1 | +30 | Power supply from fuse 6 instrument panel electrical center. |
| 2 | Signal | The pin receives B+ when the brake pedal is depressed. Connected to TCS/ESP control module pin 17. |
CONNECTOR PINS DESCRIPTION
Scheme 92
To send wheel speed to the TCS or ESP unit.
Scheme 93
Two Hall sensors which measure wheel speed using a 48-pole magnetic disc, which provides 48 pulses per rotation.
The Hall sensor sends a square pulse with a 50% pulse-rate.
The control module uses the frequency to calculate wheel speed; by measuring variation in current consumption, the frequency can be measured. The frequency increases with a corresponding increased wheel speed from 0 to 2000 Hz.
| Pin no. | Type of signal | Description |
|---|---|---|
| 1 | Power supply | From TCS/ESP control module |
| 2 | Signal | Approximately +0.85 and + 1.85 V with the sensor connected |
