- For the component list, refer to "DIAGNOSIS
DISPLAY DETAILED DESCRIPTION"
2 CHECK POWER SOURCE CIRCUIT OF COMPONENT SHOWN BY SUB-CODE
- Inspect the power source circuit of the component shown
by the sub-code.
If the power source circuit is operating normally, proceed
to the next step
Component Table:
3 CHECK RADIO AND NAVIGATION ASSEMBLY
- Disconnect the radio and navigation assembly.
- Measure the resistance according to the value(s) in the
table below.
Standard resistance
4 CHECK HARNESS AND CONNECTOR
HINT:
- Start the check from the circuit that is near the component
shown by the sub-code first.
- For details of the connectors, refer to "TERMINALS OF ECU".
- Referring to the AVC-LAN wiring diagram below, check
the AVC-LAN circuit between the radio and navigation
assembly and the component shown by the sub-code.
- Disconnect all connectors between the radio and
navigation assembly and the component shown by
sub-code.
- Check for an open or short in the AVC-LAN circuit
between the radio and navigation assembly and the
component shown by the sub-code
OK:

DESCRIPTION
When the LH / RH rear window is open 105 mm (5.91 in.) or more,
the slide door half-open stopper is
activated to force the slide door to stop at approximately 105 mm (5.91 in.)
from the fully open position.
This is caused by the jam protection function between the sli ...
Terminals of ECU
1. CHECK POWER SLIDE DOOR ECU LH (WITH
POWER SLIDE DOOR)
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.

Inspection
1. Inspect pack clearance of reverse clutch
(A) install the intermediate shaft and needle roller
bearing onto the transaxle rear cover.
(B) using a dial indicator, measure the reverse clutch
pack clearance while applying and releasing
compressed air (392 kpa, 4.0 Kgf/cm2, 57 psi).
