D1 VERIFY DTCs - Ignition OFF. - Select PARK. - Start the engine. - Carry out the OBD (On-Board Diagnostic) Test. DTCs P0706, P0707 and P0708 cannot be set by an incorrectly adjusted selector lever cable. Are only TR (Transmission Range) DTC codes present? Yes GO to D3. No GO to D2. D2 VERIFY SELECTOR LEVER CABLE/LINKAGE ADJUSTMENT - Verify that the selector lever cable/linkage is correctly adjusted. Refer to Section 307-05 See: Automatic Transmission/Transaxle > Component Tests and General Diagnostics > Transaxle Connector Layouts. Is the selector lever cable/linkage correctly adjusted? Yes GO to D3. https://my.alldata.com/repair/#/repair/article/50829/component/844/itype/382/nonstandard/858314/selfRefLink/true 1/6 6/18/2020 Pinpoint Test D: TR (Transmission Range) Sensor (Automatic Transmission/Transaxle) - ALLDATA Repair No ADJUST the selector lever cable/linkage. REFER to Section 307-05 See: Automatic Transmission/Transaxle > Component Tests and General Diagnostics > Transaxle Connector Layouts. GO to D4. D3 CHECK THE ELECTRICAL SIGNAL OPERATION - Select PARK. - Disconnect:TCM (Transmission Control Module)C1750. - Disconnect: C1520A. - Use a mirror to inspect both ends of the connectors for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals. Is there damage to the connectors, terminals or harness? Yes REPAIR as required. CLEAR the DTCs and RERUN OBD (On-Board Diagnostic) tests. No GO to D4. D4 CHECK THE TRANSMISSION VEHICLE HARNESS FOR AN OPEN - Disconnect:TCM (Transmission Control Module)C1750. - Disconnect: C1520A. - Measure the resistance for the TR (Transmission Range) sensor circuits between C1520A and the TCM (Transmission Control Module)C1750using the following chart. Is the resistance less than 5 ohms? Yes GO to D5. No REPAIR the circuit. CONNECT all components. TEST the system for normal operation. D5 CHECK THE TRANSMISSION VEHICLE HARNESS FOR A SHORT TO GROUND https://my.alldata.com/repair/#/repair/article/50829/component/844/itype/382/nonstandard/858314/selfRefLink/true 2/6 6/18/2020 Pinpoint Test D: TR (Transmission Range) Sensor (Automatic Transmission/Transaxle) - ALLDATA Repair - Disconnect: C1520B. - Measure the resistance for the TR (Transmission Range) sensor circuits between C1520A and ground using the following chart. Are all resistances greater than 10,000 ohms? Yes GO to D6. No REPAIR the circuit(s). RECONNECT all components. TEST the system for normal operation. D6 CHECK THE TRANSMISSION VEHICLE HARNESS FOR A SHORT TO VOLTAGE - Measure the voltage for the TR (Transmission Range) sensor circuits C1520A and ground using the following chart. Is any voltage present? Yes REPAIR the circuit(s). RECONNECT all components. TEST the system for normal operation. No GO to D7. D7 CHECK FOR A SHORT BETWEEN TR (Transmission Range) CIRCUITS - Measure the resistance between TR (Transmission Range) sensor circuits at the C1520Ausing the following chart https://my.alldata.com/repair/#/repair/article/50829/component/844/itype/382/nonstandard/858314/selfRefLink/true 3/6 6/18/2020 Pinpoint Test D: TR (Transmission Range) Sensor (Automatic Transmission/Transaxle) - ALLDATA Repair Are all resistances greater than 10,000 ohms? Yes GO to D8. No REPAIR the circuits. RECONNECT all components. TEST the system for normal operation. D8 CHECK FOR AN INTERNAL SOLENOID BODY OPEN FOR THE TR (Transmission Range) SENSOR CIRCUITS - Remove the main control cover. Refer to Main Control Cover See: Fluid Pan, A/T > Removal and Replacement > Main Control Cover. - Disconnect:TR (Transmission Range) Sensor Connector. - Use a mirror to inspect both ends of the connector for damage or pushed-out terminals, corrosion, loose wires and missing or damaged seals. - Measure the resistance of the TR (Transmission Range) sensor circuits between the solenoid body leadframe main connector, component side and the TR (Transmission Range) sensor connector, leadframe side. https://my.alldata.com/repair/#/repair/article/50829/component/844/itype/382/nonstandard/858314/selfRefLink/true 4/6 6/18/2020 Pinpoint Test D: TR (Transmission Range) Sensor (Automatic Transmission/Transaxle) - ALLDATA Repair Is the resistance less than 5 ohms? Yes GO to D9. No INSTALL a new solenoid body leadframe. REFER to Solenoid Body Leadframe See: Shift Solenoid, A/T > Removal and Replacement > Solenoid Body Leadframe. RECONNECT all components. TEST the system for normal operation. D9 CHECK FOR VOLTAGE AND GROUND AT THE TR (Transmission Range) SENSOR CONNECTOR - Connect:TCM (Transmission Control Module)C1750. - Connect: C1520A. - Ignition ON. - Measure the voltage on the solenoid body leadframe between TR (Transmission Range) sensor connector pins 1 (RD) and 3 (BK) solenoid body leadframe side. https://my.alldata.com/repair/#/repair/article/50829/component/844/itype/382/nonstandard/858314/selfRefLink/true 5/6 6/18/2020 Pinpoint Test D: TR (Transmission Range) Sensor (Automatic Transmission/Transaxle) - ALLDATA Repair Is the voltage greater than 10 volts? Yes INSTALL a new TR (Transmission Range) sensor. REFER to Digital Transmission Range (TR) Sensor See: Transmission Position Sensor/Switch, A/T > Removal and Replacement > Digital Transmission Range (TR) Sensor. TEST the system for normal operation. If the condition is still present, INSTALL a new TCM (Transmission Control Module). REFER to Transmission Control Module (TCM) See: Control Module, A/T > Removal and Replacement > Transmission Control Module (TCM). No INSTALL a new TCM (Transmission Control Module). REFER to Transmission Control Module (TCM) See: Control Module, A/T > Removal and Replacement > Transmission Control Module (TCM). TEST the system for normal operation. https://my.alldata.com/repair/#/repair/article/50829/component/844/itype/382/nonstandard/858314/selfRefLink/true 6/6
