STEERING COLUMN SWITCHES

1991 ACCESSORIES & SAFETY EQUIPMENT Ford Motor Co. Steering Column Switches

DESCRIPTION & OPERATION

DISABLING AIR BAG SYSTEM

To disable SRS, disconnect battery cable. Unplug back-up power supply 3-way harness connector. System is now disabled. Back-up power
supply is mounted to inside of instrument panel, left of glove box opening. Glove box door must be opened past its stops and lowered toward
floor to access back-up power supply.

ACTIVATING AIR BAG SYSTEM

To activate SRS, reconnect back-up power supply connector and negative battery cable. From passenger's side of vehicle, turn ignition switch
to RUN position. System is now activated. Check AIR BAG light to ensure system is functioning properly.

TESTING

HAZARD WARNING SWITCH & TURN SIGNAL SWITCH

Capri

1. Remove steering column covers to access turn signal/hazard switch connectors. Turn ignition on. Using a 12-volt test light, ensure

battery voltage is present at Green/Red and Green/Yellow wires at turn signal/hazard switch connectors. If battery voltage is not present,
check METER and HAZARD fuses. Also check hazard and turn signal flasher units and replace as necessary.

2. If battery voltage is present at Green/Red and Green/Yellow wires, place turn signal switch in RIGHT position. Check both Green/White

wires at switch connector. Test light should flash on and off in constant cycles.

3. Place turn signal switch in LEFT position. Check both Green/Black wires at switch connector. Test light should flash on and off in

constant cycles. If turn signal/hazard switch does not function as specified, replace switch.

Festiva

1. Remove steering column covers to access turn signal/hazard switch connectors. Turn ignition on. Using a 12-volt test light, ensure

battery voltage is present at White/Black and Black/Yellow wires at hazard and turn signal switch connectors. If battery voltage is not
present, check METER and HAZARD fuses.

2. If battery voltage is present at White/Black and Black/Yellow wires, place turn signal/hazard switch in RIGHT position. Check

Green/Black wire at switch connector. Test light should flash on and off in constant cycles.

3. Place turn signal/hazard switch in LEFT position. Check Green/White wire at switch connector. Test light should flash on and off in

constant cycles. If turn signal/hazard switch does not function as specified, replace switch.

HEADLIGHT SWITCH

Capri

1. Remove instrument panel bezel to access switch connector. See HEADLIGHT SWITCH under REMOVAL & INSTALLATION.

Disconnect switch electrical connector. Measure voltage between Red and Red/White wires of headlight switch vehicle harness and
ground. If battery voltage is present, go to next step. If battery voltage is not present, check HEAD and MAIN fuses and Red and
Red/White wires between switch and fuse block.

2. Press headlight switch to first position. Using a self powered test light or ohmmeter, check continuity between switch terminals which

correspond to Red and Red/Green wires of vehicle harness connector. Continuity should not exist. If continuity exists, replace switch.

3. Press headlight switch to second position. Check continuity between switch terminals which correspond with the Red and Red/Green

wires of vehicle harness connector. Continuity should exist. If switch does not function as described, replace headlight switch. If switch
functions as described but headlights do not work, go to next step.

4. Remove steering column covers to access Flash-To-Pass switch connector. Using a 12-volt test light or voltmeter, place switch in

position indicated in table and check voltage between indicated wire terminals and ground. See FLASH-TO-PASS SWITCH TEST
(CAPRI) table. If switch does not function as indicated, replace switch.

FLASH-TO-PASS SWITCH TEST (CAPRI)

CAUTION:

On Capri models with Supplemental Restraint System (SRS), observe safety precautions. The air bag
system is powered directly from the battery and back-up power supply. Before any repairs are
performed, disconnect and shield battery ground cable. Disconnect the back-up power supply and wait
at least 15 minutes BEFORE servicing ANY air bag component. Use caution when working near steering
column. Air bag could accidentally deploy at any time.

IGNITION SWITCH

Capri

Remove lower steering column cover to gain access to ignition switch electrical connector. Connect a self-powered test light or ohmmeter
between blade terminals indicated in table. See IGNITION SWITCH CONTINUITY (CAPRI) table. Continuity should not exist between any
blade terminal and chassis ground in any switch position except proof circuit (162/997) in START position. See
