Transaxle Range Switch (Inhibitor Switch)

TRANSAXLE RANGE SWITCH (INHIBITOR SWITCH)

OPERATION INSPECTION
1. Verify that the starter operates only with ignition switch in START position and selector lever in P or N position.
2. Verify that the back-up lights illuminate when shifted to R position with ignition switch in ON position.
3. Verify that the position of selector lever and shift pattern indicator of instrument cluster correspond.
4. If not as specified, Check the transaxle range switch.

CONTINUITY INSPECTION
1. Disconnect negative battery cable.
2. Disconnect transaxle range switch connector.





3. Check for continuity at transaxle range switch.
4. If not as specified, replace or adjust transaxle range switch.
5. Connect transaxle range switch connector.





6. Connect negative battery cable.

ATF TEMPERATURE SENSOR
Resistance inspection
1. Remove air cleaner and fresh air duct.





2. Connect ohmmeter between terminals 5 and 8.
3. Measure resistance while warming up ATF (driving vehicle).








4. Verify that the resistance drops as shown in the table and graph.

SOLENOID VALVES
RESISTANCE INSPECTION
1. Disconnect negative battery cable.
2. Disconnect solenoid valve connector.





3. Measure resistance between each terminal and a ground.
Resistance: 14 - 18 ohms

NOTE:
^ D: Torque converter clutch solenoid
^ A: Shift solenoid valve A
^ B: Shift solenoid valve B
^ C: shift solenoid valve C

4. If not correct, check wiring for an open or short-circuit. Replace solenoid valve.

CONTINUITY INSPECTION
1. Disconnect 55-pin connector from transaxle control module.





2. Check continuity between terminals A, D, G and B and C ground.
3. If not correct, check wiring for an open or short circuit.

LINEAR SOLENOID VALVE
RESISTANCE INSPECTION
1. Disconnect negative battery cable.
2. Disconnect solenoid valve connector.
3. Measure resistance between ground terminals and solenoid valve connector terminal 7.
Resistance: 4.1 - 5.1 ohms
4. If not connect, check wiring for an open or short-circuit, replace pressure control valve.
5. Connect solenoid valve connector.
6. Connect negative battery cable.

SHIFT MECHANISM
SELECTOR LEVER

Operation inspection

NOTE: Shift selector lever from P range to other ranges with ignition switch ON and brake pedal depressed.

1. Verify that selector lever can only be shifted as shown in figure.





2. Verify that there is a click at each range when shifted from P to 1 range.
3. Verify that positions of selector lever and indicator are aligned.
4. Verify that button returns smoothly when pushed.

ADJUSTMENT





1. Shift selector lever to P range.





2. Loosen the selector cable adjust nut at the transaxle side then verify that the position of selector lever is P range. (If not, turn the adjust nut to P range.).
3. Tighten the selector cable adjust nut at the transaxle side.
Tightening torque: 5.8 - 8.0 ft. lbs. (7.8 - 10.8 Nm, 0.8 - 1.1 kg-m)
