DTC C1267/67 Brake Pedal Load Sensing Switch
CIRCUIT DESCRIPTION
DTC No.DTC Detecting ConditionTrouble Area
C1267/67
Open or short circuit in brake pedal load sensing switch
continues for 0.3 secs. or more.
Immediately after IG1 is turned to the ON position, the
condition that brake pedal load sensing switch is ON and
stop lamp switch is off continues for 10 secs. or more.
While vehicle speed changes from 0 mph (0 km/h0 mph)
to 19 mph (30 km/h19 mph), the condition that the brake
pedal load sensing switch is on repeatedly occurs 5 times.

1 READ VALUE OF HAND-HELD TESTER
(a) Connect the hand-held tester to the DLC3.
(b) Start the engine.
(c) Select the DATA LIST mode on the hand-held tester.
(d) Read the value of the brake pedal load sensing switch displayed on the hand-held tester when de-
pressing and releasing the brake pedal.

REPAIR
1. INSPECT WINDOW GLASS (ANTENNA WIRE)
NOTICE:
When cleaning the glass, use a soft, dry cloth, and wipe the
glass in the direction of the wire. Take care not to damage
the wires. Do not use detergents or glass cleaners with
abrasive ingredients. When measuring voltage, wind a
piece of tin foil around the top of the negative probe and
press the foil against the wire with your finger, as shown in
the illustration.
(a) Inspect the continuity at the center of each antenna wire
as shown in the illustration.
2. REPAIR WINDOW GLASS (ANTENNA WIRE)
(a) Clean the broken wire tips with a grease, wax and silicone
remover.
(b) Place the masking tape along both sides of the wire to be
repaired.
(c) Throughly mix the repair agent (Dupont paste No. 4817).
(d) Using a fine tip brush, apply a small amount to the wire.
(e) After a few minutes, remove the masking tape.
(f) Do not repair the defogger wire for at least 24 hours.
