MANUAL TRANSMISSION - Troubleshooting <ACD> MANUAL TRANSMISSION - Troubleshooting <ACD> 22A-19 Code No.45 Pressure sensor system (Open circuit or ground) Probable cause Code No.45 is output when the output signal from the pressure sensor is below 0.2 V. D Harness or connector fault D Pressure sensor fault D 4WD-ECU fault NG MUT-II Data List No.18 Pressure sensor OK: Refer to P.22A-35 (Data List Reference Table). OK→Intermittent malfunction (Refer to GROUP 00 - Points to Note for Intermittent Malfunctions) OK OK NG Check the harness between the pressure sensor and 4WD-ECU. Check for open circuit, ground, and damage of the power line. D Check for open circuit, ground, and damage of the output line. NG→Repair OK Replace the pressure sensor. Measure at 4WD-ECU connector C-43. Measure the ECU terminal voltage. D Ignition switch: ON D Voltage between 32 and earth OK: 0.5 - 1.5 V Check the following connectors: <L.H. drive vehicles> C-43, C-128, C-134, F-24, F-29 <R.H. drive vehicles> C-43, C-134, F-24, F-29 NG→Repair MUT-II Data List No.18 Pressure sensor OK: Refer to P.22A-35 (Data List Reference Table). NG→Replace the 4WD-ECU. OK→Intermittent malfunction (Refer to GROUP 00 - Points to Note for Intermittent Malfunctions) OK Check the following connector: C-43 NG→Repair Code No.46 Pressure sensor system (open earth) Probable cause Code No.46 is output when the output signal from the pressure sensor is above 2.0 V. D Harness or connector fault D Pressure sensor fault D 4WD-ECU fault OK OK NG Check the harness between the pressure sensor and 4WD-ECU. Check for open circuit and damage of the earth line. NG→Repair OK Replace the pressure sensor. Measure at pressure sensor connector F-29. Disconnect the connector and measure at the harness side. D Resistance between terminal 3 and earth OK: 2 Ω or less Check the following connectors: <L.H. drive vehicles> F-29, C-44, C-128, C-134, F-24 <R.H. drive vehicles> F-29, C-44, C-134, F-24 NG→Repair Replace the 4WD-ECU. OK Check the following connector: F-29 NG→Repair |
