Power Slide Door System

TERMINALS OF ECU




1. CHECK POWER SLIDE DOOR ECU LH




a. Disconnect the P25 and P26 ECU connectors, and check the voltage and resistance of each terminal of the wire harness side connectors.

If the result is not as specified, there may be a malfunction on the wire harness side.







b. Reconnect the ECU connectors, and check the voltage of each terminal of the connectors.
*1 Satellite switch (Slide door LH)
*2 Power slide door control switch LH
*3 Transmitter switch (Slide door LH)
*4 When all the conditions listed below are met, the warning buzzer sounds.
- Ignition switch is turned ON
- Shift lever is moved into any position except position
- Slide door is open or power slide door system activated to open

*5 When any condition listed below is met, the sounding warning buzzer stops.
- Shift lever is moved into P position
- Slide door is fully closed

*6 Terminal SEL is used for distinction between the power slide door ECU LH and RH. Only terminal SEL of the power slide door ECU LH is grounded.

HINT: Use an oscilloscope to check the output voltages of the power slide door main switch, buzzer and pulse sensor.

If the result is not as specified, the ECU may have a malfunction.




2. CHECK POWER SLIDE DOOR ECU RH




a. Disconnect the P27 and P28 ECU connectors, and check the voltage or resistance of each terminal of the wire harness side connectors.

If the result is not as specified, there may be a malfunction on the wire harness side.







b. Reconnect the ECU connectors, and check the voltage of each terminal of the connectors.
*1 Satellite switch (Slide door RH)
*2 Power slide door control switch RH
*3 Transmitter switch (Slide door RH)
*4 When all the conditions listed below are met, the warning buzzer sounds.
- Ignition switch is turned ON
- Shift lever is moved into any position except P position
- Slide door is open or power slide door system is activated to open

*5 When any condition listed below is met, the sounding warning buzzer stops.
- Shift lever is moved into P position
- Slide door is fully closed

HINT: Use an oscilloscope to check the output voltages of the power slide door main switch, buzzer and pulse sensor.

If the result is not as specified, the ECU may have a malfunction.
