Inspection Procedure 17

INSPECTION PROCEDURE 17: Shift Switch Assembly System Vehicles with Sport Modes


























CIRCUIT OPERATION
If the select switch of the shift switch assembly is set to the sport mode, battery positive voltage will be applied to the PCM (terminal number 109). If the shift switch of the shift switch assembly is set to "UP" or "DOWN" position, battery positive voltage will be applied to the PCM (terminal number 122, 110).

COMMENT
The cause is probably a malfunction of the Park/ Neutral position switch circuit, shift switch assembly circuit or a defective PCM.

TROUBLESHOOTING HINTS (The most likely causes for this case:)
- Malfunction of the Park/Neutral position switch
- Malfunction of the shift switch assembly select switch
- Malfunction of the shift switch assembly shift switch (Up)
- Malfunction of the shift switch assembly shift switch {Down)
- Damaged harness, connector
- Malfunction of the PCM
