Wanted: ABS computer pinout.

[ultrasonic]

Does anyone have the pinout to the ABS computer? Specifically I'd like to know the wheel sensor signals at the computer.

Thanks!

I can get them. Bump this thread up to remind me if I haven't posted them by tomorrow.

vrg-- don't forget about me! Thanks.

Thanks for reminding me, Steve.

This information's from the 92 FSM. It should apply to all AWD ABS systems except the ones on 93-94 4EATs.

The ABS computer's connector looks like this:

Code: Select all

+----+----+----+----+----+----+----+----+----+----+----+----+----+----+----+----+----+----+
| 18 | 17 | 16 | 15 | 14 | xx | xx | 11 | 10 |  9 | xx |  7 | xx | xx |  4 | xx |  2 |  1 |
+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+---++--+-+--+  
  | 35 | 34 | xx | 32 | xx | xx | 29 | 28 | 27 | 26 | 25 | 24 | xx | 22 | 21 | 20 | 19 |
  +----+----+----+----+----+----+----+----+----+----+----+----+----+----+----+----+----+    

The "xx" pins are missing in the harness and are unused by the computer. That should help you figure out which way the connector is oriented.

Here are the pinouts:

1: Constant power supply
2: Left front solenoid
4: Left front sensor (-)
7: Left rear sensor (+)
9: Left rear sensor (-)
10: Ground
11: Right front sensor (+)
14: Pump monitor signal
15: Ignition-switched power supply
16: G-sensor (5MT models only)
17: Motor/solenoid power supply
18: Left rear solenoid
19: Right rear solenoid
20: Ground
21: Right front sensor (-)
22: Left front sensor (+)
24: Right rear sensor (+)
25: Brake switch
26: Right rear sensor (-)
27: Solenoid relay
28: Pump relay
29: Dash warning light
32: Solenoid monitor signal
34: Ground
35: Right front solenoid

Thanks! That's a huge help.
