INSPECTION
1. Using an ammeter:
INSPECT ONE TOUCH POWER WINDOW SYSTEM/
CURRENT OF CIRCUIT
(a) Disconnect the connector from the master switch.
(b) Connect the positive (+) lead from the ammeter to termi-
nal 1 on the wire harness side connector and the negative
(-) lead to negative (-) terminal of the battery.
(c) Connect the positive (+) lead from the battery to terminal
14 on the wire harness side connector.
(d) As the window goes down, check that the current flow is
approximately 7 A.
(e) Check that the current increases up to approximately
14.5 A or more when the window stops going down.
HINT:
The PTC opens some 4 - 90 seconds after the window stops
going down, so that check must be made before the PTC oper-
ates.
If the operation is as specified, replace the driver door ECU.
2. Using an ammeter with a current-measuring probe:
INSPECT ONE TOUCH POWER WINDOW SYSTEM/
CURRENT OF CIRCUIT
(a) Remove the driver door ECU with connectors connected.
(b) Attach a current-measuring probe to terminal 25 of the
wire harness.
(c) Turn the ignition switch ON and set the power window
switch in the down position.
(d) As the window goes down, check that the current flow is
approximately 7 A.
(e) Check that the current increases up to approximately
14.5 A or more when the window stops going down.
HINT:
The PTC opens some 4 - 90 seconds after the window stops
going down, so that check must be made before the PTC oper-
ates.
If operation is as specified, replace the driver door ECU.

cuit
CIRCUIT DESCRIPTION
The brake fluid level warning switch sends appropriate signals to the ECU when the brake fluid level is low-
ered.
HINT:
Depressing the parking brake pedal turns on the brake warning light, but this DTC No. C1202/44 is not out-
put.
DTC No.DTC Detecting ConditionTrouble Area
C1202 / 44
Fluid level in the brake master cylinder reservoir tank re-
mains low for 60 sec. or more. This means brake fluid
warning switch likes on.

INSPECTION PROCEDURE
HINT:
Start the inspection from step 1, in case of using the TOYOTA hand-held tester and start from step 2, in case
of not using the TOYOTA hand-held tester.
1 Check output value of the master cylinder pressure sensor.
PREPARATION:
(a) Connect the TOYOTA hand-held tester to the DLC3.
(b) Turn the ignition switch ON and push the TOYOTA hand-held tester main switch ON.
(c) Select the DATALIST mode on the TOYOTA hand-held tester.
CHECK:
Check that the brake fluid pressure value of the master cylinder pressure sensor displayed on the TOYOTA
hand-held tester is changing when depressing the brake pedal.
OK:
Brake fluid pressure value must be changing.
OK Go to step 4.
NG
2 Check master cylinder pressure sensor.
PREPARATION:
Install LSPV gauge to the front caliper bleeder plug portion, and
bleed the air from LSPV gauge.
SST 09709-29018
CHECK:
Start the engine and depress the brake pedal, then check the
relation between the fluid pressure and voltage of PMC and E2
terminals of the master cylinder pressure sensor with connector
still connected.
OK:
Front brake caliper fluid pressureVoltage
0 kPa (0 Kgf/cm2, 0 psi)0.44 - 0.76 V
5,883 kPa (60 kgf/cm2, 853 psi)1.34 - 1.66 V
11,768 kPa (120 kgf/cm2, 1,706 psi)2.24 - 2.56 V
HINT:
Voltage between terminals VCM and E2: 4.7 - 5.3 V
NG Replace master cylinder pressure sensor.
OK
