TIGOR EV SERVICE MANUAL

BRAKES 64 16.14. VACUUM SENSOR REMOVAL 1. Turn off ignition switch 2. Disconnect electrical connector of vacuum Sensor. 3. Disconnect vacuum hose from Sensor. 4. While refitment of Sensor, Ensure the connector orientation should be parallel to ground as shown in view. 5. Ensure the Arrow mark port on Booster side hose. 6. ReConnect the Electrical connector of vacuum sensor. 17. TROUBLE SHOOTING & DIAGNOSIS General information: While the ignition is in position II, the ABS ECU monitors the system for faults. Diagnostic information and system function monitoring can be accessed by connecting diagnostic software to the vehicle diagnostic connector. After detecting a fault, the ABS ECU will select a suitable default strategy which will retain, if possible, some operational ABS capability. If ABS is not active, conventional braking will be remain available. Fault codes are stored in the ECU’s memory which can be accessed, read and then cleared when the fault is rectified. (a) During driving the vehicle with ABS operative: 1. Observe warning lights, check parking brake/fluid warning light extinguishes after initial bulb check or when parking brake is released, indicating that power assistance is available. 2. In road conditions where surface friction is sufficient to slow or stop the vehicle without wheel lock, ABS does not operate. 3. In an emergency braking situation, if one or more wheels begin to slow rapidly in relation to vehicle speed, ABS will detect wheel locking tendency and will regulate brake pressure to maintain wheel rotation. (b) Brake application with partial failure: Warning: If a fault develops in the brake system it is essential that it is investigated immediately. NOTE: If, during braking, a drastically reduced resistance is detected at pedal and braking effectiveness is very much reduced, failure of the non-powered (master cylinder) portion of system is indicated. When this occurs, DO NOT PUMP BRAKE PEDAL. Push the pedal through free movement to obtain braking effort from the power circuit. It is essential that brake pedal travel is not obstructed by items such as extra floor mats. 1. When power assistance is not available, ABS braking is not operative. Both warning lights are illuminated. Braking effort is available from master cylinder only. This result in longer pedal travel and greater pedal effort required to decelerate vehicle.
