3 POWER SOURCE RESET
- Disconnect the ECU-B fuse and reconnect it. 10 seconds later, check that the slide door closer is operational.
4 INSPECT POWER SLIDE DOOR LOCK ASSEMBLY
- Apply battery voltage to the terminals and check the motor operation.
OK
- At each range of the latch, inspect the resistance of the pawl switch and latch switch.
Resistance
- Inspect the resistance of the original position switch and handle switch.
