General Description
When the shift lever is in the D (Drive) position the output signal of Transaxle Range Switch is 12 V and in all other positions the voltage is 0 V. The TCM judges the shift lever position by reading all signals, for the TRANSMISSION Range Switch, simultaneously.

DTC Description
The TCM sets this code when patterns are out of specification based on the table shown below.
The TRANSMISSION Range Switch has no output signal for an extended period of time.

DTC Detecting Condition:

Specification:

Schematic Diagram:

Monitor Scantool Data
1. Connect scantool to data link Connector (DLC)
2. Ignition "ON" & Engine "OFF".
3. Monitor the "TRANSMISSION RANGE SWITCH" parameter on the scantool
4. Move selector lever from "P" range to "D" range.






5. Does "TRANSMISSION RANGE SWITCH" follow the reference data?

YES
a. Fault is intermittent caused by poor contact in the sensor's and/or PCM/TCM's connector or was repaired and PCM/TCM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure

NO
a. Go to "W/Harness Inspection" procedure

Terminal and Connector Inspection
1. Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?

YES
a. Repair as necessary and go to "Verification of Vehicle Repair" procedure

NO
a. Go to "Power Circuit Inspection" procedure

Signal Circuit Inspection
1. Disconnect "M62" connector
2. Ignition "ON" & Engine "OFF".
3. Measure voltage between terminal "2" of the "M62" connector(M62) and chassis ground.

Specification : approx. 5 V






4. Is voltage within specifications?

YES
a. Go to "Signal Circuit Inspection" procedure

NO
a. Check for open or short in harness and Fuse. Repair as necessary and Go to "Verification of Vehicle Repair" procedure.

Component Inspection
1. Connect "TCU" connector.
2. Ignition "ON" & Engine "OFF".
3. Move select lever to "SPORTS MODE" and operate select lever to up and down.
4. Measure voltage between terminal "16, 17, 61" of the "TCU" connector(C120) and chassis ground.

Specification :






5. Is voltage within specifications?

YES
a. Substitute with a known-good "TCU" and check for proper operation. If the problem is corrected, replace "TCU" and Go to "Verification of Vehicle Repair" procedure

NO
a. Check for open or short between "M62" and "C120" harness. Repair as necessary and Go to "Verification of Vehicle Repair" procedure.

Verification of Vehicle Repair
After a repair, it is essential to verify that the fault has been corrected.
1. Connect scan tool and select "Diagnostic Trouble Codes (DTCs)" mode.
2. Using a scantool, Clear DTC.
3. Operate the vehicle within DTC Enable conditions in General information.
4. Are any DTCs present?

YES
a. Go to the applicable troubleshooting procedure.

NO
a. System performing to specification at this time.
