P1805 BRAKE SWITCH
DescriptionINFOID:0000000003856776
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 being driver.

< PRECAUTION >[VQ25DE, VQ35DE]
PRECAUTIONS
CAUTION:
 Always turn the ignition switch OFF and disconnect the negative battery cable before any repair or
inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will cause
the MI to illuminate.
 Always connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to illuminate due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
 Certain systems and components, especially those related to OBD, may use a new style slide-lock-
ing type harness connector. For description and how to disconnect, refer to PG-96, "
Description".
 Always to route and secure the harnesses properly after work. The interference of the harness with a
bracket, etc. may cause the MI to illuminate due to the short circuit.
 Always connect rubber tubes properly after work. A misconnected or disconnected rubber tube may
cause the MI to illuminate due to the malfunction of the EVAP system or fuel injection system, etc.
 Always erase the unnecessary malfunction information (repairs completed) from the ECM and TCM
(Transmission control module) before returning the vehicle to the customer.
General PrecautionsINFOID:0000000003856881
Always use a 12 volt battery as power source.
Never attempt to disconnect battery cables while engine is
running.
Before connecting or disconnecting the ECM harness con-
nector, turn ignition switch OFF and disconnect negative bat-
tery cable. Failure to do so may damage the ECM because
battery voltage is applied to ECM even if ignition switch is
turned OFF.
Before removing parts, turn ignition switch OFF and then dis-
connect battery ground cable.
Never disassemble ECM.
If a battery cable is disconnected, the memory will return to the ECM value.
The ECM will now start to self-control at its initial value. Thus, engine operation can vary slightly in
this case. However, this is not an indication of a malfunction. Never replace parts because of a slight
variation.
If the battery is disconnected, the following emission-related diagnostic information will be lost
within 24 hours.
-Diagnostic trouble codes
-1st trip diagnostic trouble codes
-Freeze frame data
-1st trip freeze frame data
-System readiness test (SRT) codes
-Test values
When connecting ECM harness connector, fasten (B) it
securely with a lever (1) as far as it will go as shown in the fig-
ure.

1. Visually inspect EVAP vapor lines for improper attachment and for cracks, damage, loose connections,
chafing and deterioration.
2. Check EVAP canister as per the following:
a. Block port (B). Orally blow air through port (A).
Check that air flows freely through port (C).
b. Block port (A). Orally blow air through port (B).
Check that air flows freely through port (C).
3. Inspect fuel tank filler cap vacuum relief valve for clogging, stick-
ing, etc.
a. Wipe clean valve housing.
b. Check valve opening pressure and vacuum.
c. If out of specification, replace fuel filler cap as an assembly.
