Parking Brake Switch Test
1. Remove the parking brake cover,
2. Disconnect the connector from the parking brakeswitch.
3. Check for continuity between the terminal and bodyground in each position according to the table.

NOTE (Canada): lf the parking brake switch is OK, butthe brake system indicator does not function, perform
the input test for the daytime running lights control unit(see section 23).
Brake Fluid Level Switch Test
1. Remove the reservoir cap. Check that the float
moves up and down freely; if it doesn't, replace the
reservoir cap assembly.
2. Check for continuity between the terminals in each
switch position according to the table.

Daytime Running Lights Control Unit Input Test (Canadal
1.Remove the driver's dashboard lower cover and the
knee bolstet (see section 20).
Disconnect the connectors from the daytime run-
ning lights control unit.
Inspect the connector and socket terminals to be
sure they are all making good contact.
lf the terminals are bent, loose or corroded, repair
them as necessary, and recheck the system.
lf the terminals look OK, make the tollowing
inout tests at the connector'
- lf anv test indicates a problem, find and correct
the cause, then recheck the system.
- lf all the input tests prove OK, the control unrt

Dafime Running Lights Resistor
Test (Canada)
CAUTION: The d.ytime running lights resistor becomesvery hot when the daytime running lights are on; do nottouch it or the attaching hardware immediately allerthe lighls have been turned off.
1. Disconnect the 3P connector from the resistor.
Measure the resistance between the resistor termi-nal No. 1 (or No. 2) and the power terminal No. 3.
Resistance: 1.0 - 2.0 O
Replace the resistor with a new one if any of theresistances are beyond specification.

CAUTION: Halogen headlights bGcome very hot in use;do not touch them or the attaching hardware immedi-ately after they have been turned oft.
1. Remove the front bumper (see section 2O).
2. Remove the mounting bolts.
3. Disconnect each connector, then remove the head-light assembly.
