TROUBLESHOOTING
NOTICE:
When replacing the internal mechanism (computer part) of the audio system, be careful that no part
of your body or clothing comes in contact with the terminals of the leads from the IC, etc. of the re-
placement part (spare part).
HINT:
This inspection procedure is a simple troubleshooting which should be carried out on the vehicle during sys-
tem operation and was prepared on the assumption of system component troubles (except for the wires and
connectors, etc.).
Always inspect the trouble taking the following items into consideration.
Open or short circuit of the wire harness
Connector or terminal connection fault
For audio systems with anti-theft system, troubleshooting items marked ( * ) indicate that ºTrou-
bleshooting for ANTI-THEFT SYSTEMº should be carried out first.

BRAKE PEDAL
ON-VEHICLE INSPECTION
1. CHECK THAT PEDAL HEIGHT IS CORRECT
Pedal height from asphalt sheet:
154.2 - 164.2 mm (6.071 - 6.465 in.)
If the pedal height is incorrect, adjust it.
2. IF NECESSARY, ADJUST PEDAL HEIGHT
(a) Remove the lower instrument panel and finish panel.
(b) Disconnect the connector from the stop light switch.
(c) Loosen the stop light switch lock nut and remove the stop
light switch.
(d) Loosen the push rod lock nut.
(e) Adjust the pedal height by turning the pedal push rod.
(f) Tighten the push rod lock nut.
Torque: 25 N´m (260 kgf´cm, 19 ft´lbf)
(g) Install the stop light switch and turn it until it lightly con-
tacts the pedal stopper.
(h) Turn the stop light switch back one turn.
(i) Check the clearance (A) between stop lights switch and
pedal.
Clearance: 0.5 - 2.4 mm (0.020 - 0.094 in.)
(j) Tighten the stop light switch lock nut.
(k) Connect the connector to the stop light switch.
(l) Check that the stop lights come on when the brake pedal
is depressed, and go off when the brake pedal is re-
leased.
(m) After adjusting the pedal height, check the pedal freeplay.
If clearance (A) between the stop light switch and the brake
pedal stopper has been adjusted correctly, the pedal freeplay
will meet the specifications.
(n) Install the lower instrument panel and finish panel.
3. CHECK PEDAL FREEPLAY
(a) Stop the engine and depress the brake pedal several
times until there is no more vacuum left in the booster.
(b) Push in the pedal by hand until the second point of resis-
tance begins to be felt, then measure the distance, as
shown.
Pedal freeplay: 1 - 6 mm (0.04 - 0.24 in.)
If incorrect, check the stop light switch clearance. If the clear-
ance is OK, then troubleshoot the brake system.

HINT:
The freeplay to the 1st point of resistance is due to the play be-
tween the clevis and pin. It is 1 - 3 mm (0.04-0.12 in.) on the
pedal.
4. CHECK PEDAL RESERVE DISTANCE
(a) Release the parking brake.
(b) With the engine running, depress the pedal and measure
the pedal reserve distance, as shown.
Pedal reserve distance at 490 N (50 kgf, 110.2 lbf):
2JZ-GE Engine: More than 72 mm (2.83 in.)
2JZ-GTE Engine: More than 70 mm (2.76 in.)
If the reserve distance is incorrect, troubleshoot the brake sys-
tem.
