MANUAL TRANSMISSION - Troubleshooting <ACD> 22A-11 Code No.25 Wrong-diameter tire Probable cause Code No.25 is output as wrong-diameter tire when one of the four vehicle speeds is outside the range of specified values in respect to the average of the four vehicle speed sensors, when the vehicle speed is above 20 km/h with the steering wheel in the straight ahead position. However the warning lamp does not light up. D Tire fault D Wheel speed sensor fault D Rotor fault D Wheel bearing fault D Harness or connector fault D ABS-ECU fault <Vehicles with ACD and AYC> D 4WD-ECU fault <Vehicles with ACD and AYC> OK NG OK Check the following connector: C-44 NG→Repair Check the following connectors: <L.H. drive vehicles> C-44, B-123 <R.H. drive vehicles> C-44, C-147, B-123 NG→Repair OK YES OK OK Check the wheel speed sensor and rotor. (Refer to GROUP 35B - Wheel Speed Sensor.) NG→Repair Check the wheel speed sensor output voltage. (Refer to GROUP 35B - On-vehicle Service.) OK Check the wheel speed sensor installation. NG→Repair NG OK Check the wheel beearing. (Refer to GROUP 26 - On-vehicle Service, and GROUP 27B - Rear Hub Assembly.) NG→Repair OK Check the following connectors: <L.H. drive vehicles> B-123, A-03, A-37, D-10, D-04, D-30, C-146, C-111, C-128, A-43 <R.H. drive vehicles> B-123, A-03, A-37, D-10, D-04, D-30, C-146, C-111, C-128, C-136 NG→Repair NG MUT-II Data List No.01 Vehicle speed sensor <FR> D No.02 Vehicle speed sensor <FL> D No.03 Vehicle speed sensor <RR> D No.04 Vehicle speed sensor <RL> OK: The speed meter display and MUT-II display match. OK→Intermittent malfunction (Refer to GROUP 00 - Points to Note for Intermittent Malfunctions.) Measure at 4WD-ECU connector C-44. Measure the ECU terminal voltage. D Ignition switch: ON D Rotate the tire corresponding to the measured terminal by one and a half to one rotate per second. (1) Voltage between terminal 9 and body earth <FR> (2) Voltage between terminal 6 and body earth <FL> (3) Voltage between terminal 7 and body earth <RR> (4) Voltage between terminal 8 and body earth <RL> OK: Changes by 0 V ↔ 5 V. MUT-II Data List No.01 Vehicle speed sensor <FR> D No.02 Vehicle speed sensor <FL> D No.03 Vehicle speed sensor <RR> D No.04 Vehicle speed sensor <RL> OK: The speed meter display and MUT-II display match. NG→Replace the 4WD-ECU. OK→Intermittent malfunction (Refer to GROUP 00 - Points to Note for Intermittent Malfunctions) Refer to GROUP 35B - Troubleshooting. (Refer to Diagnosis Code No.11, 12, 13, 14, 21, 22, 23, and 24.) Are all four wheels mounted to normal tires? NO→Repair Check the harness between the ABS-ECU and each wheel speed sensor. Check for open circuit and ground of the output line. D Check for open circuit and damage of the earth line. NG→Repair OK Check the harness between the 4WD-ECU and ABS-ECU. Check for open circuit, ground and damage of the power line. NG→Repair OK |
