Shift Lock Control Unit Inspection Table
WARNING: This page is about a different car, the 2008 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.
Shift lock control unit terminal data are reference values, measured between each terminal and ground.
SHIFT LOCK CONTROL UNIT INSPECTION TABLE
| Terminal (Wire color) | Item | Condition | Judgement standard |
|---|---|---|---|
| 1 (Y/R) | Power source | Always | Battery voltage |
| 2 (BR/Y) | Detention switch (for key) | When selector lever is not in "P" position with key inserted or ignition knob switch pushed. | Battery voltage |
| When selector lever is in "P" position with key inserted. | Approx. 0V | ||
| 3 (L/W) | Detention switch (for shift) | When selector lever is not in "P" position. | Battery voltage |
| When selector lever is in "P" position. | Approx. 0V | ||
| 4 (P/L) | Stop lamp switch | When brake pedal is depressed | Battery voltage |
| When brake pedal is released | Approx. 0V | ||
| 5 (BR) | Vehicle speed signal (8pulse signal) | Speed meter is operated | Refer to "TERMINALS AND REFERENCE VALUE FOR UNIFIED METER AND A/C AMP. ". |
| 6 (G) | Ignition signal | Ignition switch: OFF | Approx. 0V |
| Ignition switch: ON | Battery voltage | ||
| 7 (R/W) | Shift lock solenoid |
|
Approx. 0V |
| Except the above | Battery voltage | ||
| 8 (B) | Ground | - | Approx. 0V |
| 9 (R) | Key lock solenoid | When selector lever is not in "P" position. | Battery voltage for approx. 0.1 sec. (Note) |
| When selector lever is in "P" position. | Approx. 0V | ||
| 10 (W/G) | Key unlock solenoid | When selector lever is in "P" position with ignition switch OFF. | Battery voltage for approx. 0.1 sec. (Note) |
| When selector lever is not in "P" position with ignition switch OFF. | Approx. 0V |
NOTE:
Take care that the pointer swings only momentarily because the output time is so short. If the inspection is done with an oscilloscope, it should be observed that the power source voltage lasts for 3.5 to 10 ms.
