8W - 35 - 8
DESCRIPTION AND OPERATION (Continued)
The solenoids use a common ground on the Z1 cir-
cuit. There are two Z1 circuits from the modulator.
Both of these grounds terminate at the right frame
rail, and are spliced in with the ABS pump motor
and the ABS system relay.
WHEEL SPEED SENSORS
There are four wheel-speed sensors, one at each
wheel. The sensors use a tone wheel to determine
wheel speed. Input to the Controller Anti Lock
Brakes (CAB) is done on the following circuits, each
of which is a twisted pair:
B8 and B9 for the left front wheel (cavity 8 and
cavity 9).
B6 and B7 for the right front wheel (cavity 6 and
cavity 7).
B3 and B4 for the left rear wheel (cavity 3 and cav-
ity 4).
B1 and B2 for the right rear wheel (cavity 1 and
cavity 2).
BRAKE SWITCH INPUT
Circuit L50 is an input to the Controller Anti Lock
Brake (CAB). The L50 connects to cavity 13 of the
CAB connector. Circuit L50 is spliced in with the
stop lamps, and is used to provide the CAB with
information on when the brakes are being applied.
8W - 35 ANTI-LOCK BRAKES
PARK BRAKE SWITCH INPUT
Circuit G9 provides a park brake switch input to
the Controller Anti-Lock Brakes (CAB). This circuit
connects to cavity 14 of the CAB.
DATA LINK CONNECTOR
Circuit D21 is used for diagnostics of a fault within
the ABS system. It is spliced in with the Powertrain
Control Module (PCM) circuits, and is used as an
output from the Controller Anti Lock Brake (CAB).
Circuit D21 connects to cavity 51 of the CAB connec-
tor.
HELPFUL INFORMATION
• Check the 10 amp fuse located in cavity 10 of
the PDC
• Check the 40 amp fuse located in cavity 13 of
the PDC
• Check the 20 amp fuse located in cavity 2 of the
PDC
• Check for a good ground at the right frame rail
• Check the case ground on the CAB
• Refer to the appropriate group of the Service
Manual, or the Diagnostic Test Procedures Manual.
