Subject:
Revised Cruise Control Switch

Application:
1990-91-1/2 900 and 9000 Models


Supersedes PSI 12/90-0075 (Sec. 3, p. 5)

Incorrect adjustment of the brake or clutch switches can cause the cruise control system to be inoperative. Typically the customer complaint is that the cruise control speed set function does not work. The brake and clutch switches (both switches are identical) were modified beginning with 1990 models to incorporate a self-adjusting ratcheting mechanism. This ratcheting mechanism can sometimes over-adjust (ratchet too far in) preventing the pedal from depressing the switch's pushrod actuator when the pedal is at rest, leaving an open circuit in the switch.





Beginning with the VIN's listed below, a revised pedal switch that has a greater resistance to over-adjusting was introduced into production. This switch, P/N 43 50 443, is available as a replacement to remedy complaints of switches that over adjust.

NOTE
With the introduction of this now switch, the modification procedure described in PSI 12/90-0075 (Sec. 3, p. 5) should no longer be performed. Replace the faulty pedal switch with a now replacement switch.

Before replacing the pedal switch on cars with manual transmission, however, the clutch pedal operation should be checked to make sure it is returning completely (see PSI 07/90-0012, Sec. 4, p. 1). If one switch on a car with manual transmission requires replacement, the other switch should also be replaced at the same time.

The revised pedal switch was introduced into production as follows:

900: M2500209-, M7001460-

9000: M1027855-

Parts Required:

Pedal Switch P/N 43 50 443
