Note:

Control unit terminals for FL solenoid valve:

ABS-2E:                Ter. 2 and 20

ABS-2EH with ETC:           Intern.

ABS-2EH without ETC:      Intern.

ETC = Electronic Traction Control

For the ABS-2EH, the official Opel/Vauxhall circuit diagrams designate the control unit terminals for the solenoid valves as inaccessible. There is, however, a 6-pin oblong plug on the upper side of the hydraulic modulator (under the cover) which connects the solenoid valves and the control unit. (FL solenoid valve: Ter.1 and 2).

Notes for Trouble-shooting:

Nominal Value:
