Diagnostic ProcedureEBS00KCK
1.CHECK PNP SWITCH GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch “OFF”.
2. Disconnect PNP switch harness connector.
3. Check harness continuity between PNP switch terminal 2 and
body ground.
Refer to Wiring Diagram.
4. Also check harness for short to power.
OK or NG
OK >> GO TO 2.
NG >> Repair open circuit or short to power in harness or con-
nectors.
2.CHECK PNP SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Disconnect ECM harness connector.
2. Check harness continuity between ECM terminal 102 and PNP switch terminal 1.
Refer to Wiring Diagram.
3. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 3.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
3.CHECK PNP SWITCH
Refer to AT- 111 , "
DTC P0705 PARK/NEUTRAL POSITION (PNP) SWITCH" (A/T models) or MT-21 (M/T
models).
OK or NG
OK >> GO TO 4.
NG >> Replace PNP switch.
4.CHECK INTERMITTENT INCIDENT
Refer to EC-109, "

DTC P1805 BRAKE SWITCH
PFP:25320
DescriptionEBS00KCL
Brake switch signal is applied to the ECM through the stop lamp switch when the brake pedal is depressed.
This signal is used mainly to decrease the engine speed when the vehicle is driving.
CONSULT-II Reference Value in Data Monitor ModeEBS00KCM
Specification data are reference values.
On Board Diagnosis LogicEBS00KCN
The MI will not light up for this self-diagnosis.
FALI-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MI lights up.
DTC Confirmation ProcedureEBS00KCO
WITH CONSULT-II
1. Turn ignition switch “ON”.
2. Fully depress the brake pedal for at least 5 seconds.
3. Erase the DTC with CONSULT-II.
4. Select “DATA MONITOR” mode with CONSULT-II.
5. If 1st trip DTC is detected, go to EC-362, "
Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.

Engine operating condition in fail-safe mode
ECM controls the electric throttle control actuator by regulating the throttle opening to a small range.
Therefore, acceleration will be poor.

IGNITION SIGNALPFP:22448
Component DescriptionEBS00KCS
IGNITION COIL & POWER TRANSISTOR
The ignition signal from the ECM is sent to and amplified by the
power transistor. The power transistor turns on and off the ignition
coil primary circuit. This on-off operation induces the proper high
voltage in the coil secondary circuit.
