ABS <4WD> - Troubleshooting 35B-11 Code No.32 Longitudinal G sensor system Probable cause This code is output in the following cases. If the longitudinal G sensor output voltage is less than 0.5 V or more than 4.5 V <open circuit or short circuit of longitudinal G sensor circuit> D If the longitudinal G sensor output voltage does not change <longitudinal G sensor output voltage: fixed> D Malfunction of longitudinal G sensor D Malfunction of wiring harness or connector D Malfunction of hydraulic unit and ABS-ECU (1) NG NG Repair NG Check the harness wire, and repair if necessary. Between ignition switch and longitudinal G sensor OK Check the trouble symptom. Check the following connectors: D-32, C-210, C-213 NG Repair NG OK Check the trouble symptom. OK (2) NG Measure at the longitudinal G sensor connector D-32. Disconnect the connector, and measure at the harness side connector. (1) Voltage between 1 and body earth (Ignition switch: ON) OK: System voltage (2) Continuity between 3 and body earth OK: Continuity Repair Check the following connectors: B-123, C-128 <R.H. drive vehicles>, C-130 <L.H. drive vehicles>, D-32 NG OK Repair Check the harness wire. Between longitudinal G sensor and ABS-ECU Replace the hydraulic unit and ABS-ECU. MB991348 <Horizontal position> <With front mark downward> D-32 Harness side connector NG OK NG Repair NG OK Check the trouble symptom. Check the following connectors: B-123, C-128, D-32 D Remove the longitudinal G sensor. (Refer to P.35B-35.) D Connect the special tool between the harness side connector D-32 and the longitudinal G sensor. D Ignition switch: ON D Voltage between 2 and body earth OK: 2.4 - 2.6 V (horizontal position) 3.3 - 3.7 V (with front mark downward) NG OK Repair Check the harness wire. Between longitudinal G sensor and ABS-ECU Replace the hydraulic unit and ABS-ECU. Replace the longitudinal G sensor. |
