Brake Actuator

1. Ensure battery voltage is approximately 12 volts.
2. On 4WD Celica models, remove vinyl tube covering wire harness of actuator checker tool No. 0990-00150, then tape separated harness.
3. On all models, disconnect actuator connectors.
4. On T100 models, disconnect solenoid relay connector.
5. On all models, connect actuator checker, tool Nos. 09990-00150, 09990-00200, 09990-00205 or 09990-00210 to actuator and inspect as follows:
a. On Celica 2WD models, connect actuator checker to actuator control relay and body side wire harness using sub-wire harness No. 09990-00165.
b. On 4WD Celica, Supra, Pickup, 4Runner and MR2 and Previa models, connect actuator checker to actuator and body side wire harness using sub-wire harness.
c. On Camry models, connect actuator checker to actuator control relay and body side wire harness through sub wire harness C and E.
d. On T100 models, connect actuator checker to actuator control relay, solenoid relay and body side wire harness using sub-wire harness.
e. On all models, connect red cable of checker to battery positive terminal and black to negative terminal. Connect black cable of sub-wire harness to battery negative terminal or body ground.
f. On Celica, Camry and Corolla, place checker type "Sheet A" tool No. 09990-00163 on actuator checker.
g. On Supra , substitute "motor" for "sub-motor," and "solenoid" for "main" switch on actuator when referring to following steps.
h. On all models, start engine and run at idle.
i. On models with four wheel ABS, turn selector switch of actuator checker to "Front RH" position.
j. On models with four wheel ABS, press and hold in "motor" switch for a few seconds, then press brake pedal and hold it for 15 seconds. Press motor switch for a few seconds and ensure brake pedal does not pulsate.
k. On models equipped with rear wheel ABS, turn selector switch to "Rear" position.
l. On all models, depress brake pedal and hold, then press power switch, ensure brake pedal does not go down. Do not press power switch for more than 10 seconds. Release power switch, ensure brake pedal goes down, then press motor or sub motor switch, ensuring pedal returns.
m. Release pedal.
n. Inspect other wheels by repeating steps F through I.
o. After testing has been completed remove "Sheet A" from actuator checker and sub-wire harness from actuator. Connect actuator and/or control relay connectors.
p. Clear diagnostic Trouble codes.
