Toyota Sienna Service Manual: Power Slide Door LH does not Operate When Using Inside / Outside Handle
DESCRIPTION
- The inside / outside handles have the ability to control operation of the power slide door. Pulling either handle transmits a request signal to the power slide door ECU LH, which then commands the power slide door control motor and clutch to open / close the power slide door.
- The slide door lock remote control assembly has the handle operation detect switch for detection of switch operation and also the child protection detect switch for the child lock function that disables the power slide door control switch LH function while the child lock is ON.
- If there is a malfunction detected in these 2 detection switches or the wire harness, replace the slide door lock remote control assembly LH.

INSPECTION PROCEDURE
1 OPERATION CHECK
- If the power slide door does not operate when trying to open it, proceed to A.
- If the power slide door does not operate when trying to close it, proceed to B.
2 CHECK SLIDE DOOR CLOSER SYSTEM
- Check if the slide door closer system operates.
3 READ VALUE OF INTELLIGENT TESTER
- Using the intelligent tester, check the DATA LIST for proper functioning of the handle operation detect switch.
OK (Power slide door ECU LH):
4 INSPECT SLIDE DOOR LOCK REMOTE CONTROL SUB-ASSEMBLY LH (HANDLE OPERATION DETECT SWITCH)
- Inspect the resistance of the switch.

5 CHECK WIRE HARNESS (SLIDE DOOR LOCK REMOTE CONTROL - POWER SLIDE DOOR ECU LH)
- Disconnect the S20 remote control and P25 ECU connectors.
- Check the resistance between the wire harness side connectors.
Resistance (Check for open circuit)
- Check the resistance between the S20 remote control connector and body ground.
Resistance (Check for open circuit)
REPLACE POWER SLIDE DOOR ECU LH
6 READ VALUE OF INTELLIGENT TESTER
- Using the intelligent tester, check the DATA LIST for proper functioning of the child protection detect switch.
OK (Power slide door ECU LH):
7 INSPECT SLIDE DOOR LOCK REMOTE CONTROL SUB-ASSEMBLY LH (CHILD PROTECTION DETECT SWITCH)
- Inspect the resistance of the switch.
Resistance
8 CHECK WIRE HARNESS (SLIDE DOOR LOCK REMOTE CONTROL - POWER SLIDE DOOR ECU LH)
- Disconnect the S20 switch and P25 ECU connectors.
- Check the resistance between the wire harness side connectors.
Resistance (Check for open circuit)
- Check the resistance between the S20 switch connector and body ground.
Resistance (Check for open circuit)
REPLACE POWER SLIDE DOOR ECU LH

DTC B0117/45 Short to GND in Side Squib LH Circuit
DESCRIPTION
The side squib LH circuit consists of the center airbag sensor assembly and
the front seat side airbag
assembly LH.
This circuit instructs the SRS to deploy when deployment conditions are met.
DTC B0117/45 is recorded when a s ...
Diagnosis system
1. CHECK DLC3
The vehicle's ECU uses ISO 15765-4 for
communication protocol. The terminal arrangement
of the DLC3 complies with SAE J1962 and matches
the ISO 15765-4 format.
NOTICE:
*: Before measuring the resistance, leave the
vehicle as is for at least 1 minute and do ...
