ASCD BRAKE SWITCH
DescriptionINFOID:0000000003858142
When the brake pedal is depressed, ASCD brake switch is turned OFF and stop lamp switch is turned ON.
ECM detects the state of the brake pedal by two kinds of input (ON/OFF signal).
Refer to EC-51, "
System Diagram" for the ASCD function.
Component Function CheckINFOID:0000000003856821
1.CHECK ASCD BRAKE SWITCH FUNCTION
With CONSULT-III
1. Turn ignition switch ON.
2. Select “BRAKE SW1” in “DATA MONITOR” mode with CONSULT-III.
3. Check “BRAKE SW1” indication under the following conditions.
Without CONSULT-III
1. Turn ignition switch ON.
2. Check the voltage between ECM harness connector and ground.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to EC-321, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000003856822
1.CHECK ASCD BRAKE SWITCH POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ASCD brake switch harness connector.
3. Turn ignition switch ON.
4. Check the voltage between ASCD brake switch harness connector and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> GO TO 2.
2.DETECT MALFUNCTIONING PART
Check the following.

SWITCH POSITIONS
Switches are shown in wiring diagrams as if the vehicle is in the “normal” condition.
A vehicle is in the “normal” condition when:
Number Item Description
1 Power supply  This means the power supply of fusible link or fuse.
2 Fusible link  “X” means the fusible link.
3Number of fusible link/
fuse This means the number of fusible link or fuse location.
4 Fuse  “/” means the fuse.
5Current rating of fus-
ible link/fuse This means the current rating of the fusible link or fuse.
6 Optional splice  The open circle shows that the splice is optional depending on vehicle application.
7 Connector number The letter shows which harness the connector is located in.
 Example “M”: main harness. For detail and to locate the connector, refer to, .PG-83, "
How
To Read Harness Layout",PG-85, "Main Harness"
8Splice
 The shaded circle “ ” means the splice.
9 Page crossing  This circuit continues to an adjacent page.
10 Option abbreviation
 This means the vehicle specifications which layouts the circuit between “ ”.
11 Relay  This shows an internal representation of the relay.
12 Option description  This shows a description of the option abbreviation used on the page.
13 Switch This shows that continuity exists between terminals 1 and 2 when the switch is in the A
position. Continuity exists between terminals 1 and 3 when the switch is in the B position.
14 Circuit (Wiring)  This means the wiring.
15 System branch  This shows that the circuit is branched to other systems.
16 Shielded line  The line enclosed by broken line circle shows shield wire.
17 Component name  This shows the name of a component.
18 Ground (GND)  This shows the ground connection.
19 Connector This means the connector information.
 This unit-side is described by the connector symbols.
20 Connectors  This means that a transmission line bypasses two connectors or more.
21 Wire color This shows a code for the color of the wire.
B = Black
W = White
R = Red
G = Green
L = Blue
Y = Yellow
LG = Light GreenBR = Brown
OR or O = Orange
P = Pink
PU or V (Violet) = Purple
GY or GR = Gray

CH = Dark Brown
DG = Dark Green
 When the wire color is striped, the base color is given first, followed by the stripe color as
shown below:
Example: L/W = Blue with White Stripe
22 Terminal number  This means the terminal number of a connector.

Fuse,
Connector and Terminal Arrangement" for relay terminal assignment.
Is the inspection result normal?
YES >> GO TO 8.
NO >> Inspection the power supply circuit. Refer to PG-55, "
Wiring Diagram - IGNITION POWER SUP-
PLY -".
8.CHECK BLOWER RELAY
1. Turn the ignition switch OFF.
2. Install the blower relay. Refer to PG-101, "
Fuse, Connector and Terminal Arrangement".
3. Turn the ignition switch ON.
4. Check the operating sound of blower relay.
Is the inspection result normal?
YES >> GO TO 9.
NO >> Replace the blower relay.
