id0902t1990100
Description |
Walk-in actuator (RH) circuit malfunction |
---|---|
Detection condition
|
• Rear one-touch walk-in control module detects a short to power supply in the walk-in actuator (RH) circuit.
|
Fail-safe
|
• Inhibits the rear one-touch walk-in operation function from being driven for the second-row seat (RH).
|
Possible cause
|
• Walk-in actuator (RH) connector or terminal malfunction (L.H.D.)
• Rear one-touch walk-in control module connector or terminal malfunction
• Short to power supply in wiring harness between the following circuits:
• Walk-in actuator (RH) malfunction
• Rear one-touch walk-in control module malfunction

|
INSPECT WALK-IN ACTUATOR (RH) CONNECTOR CONDITION
• Switch the ignition off.
• Disconnect the negative battery terminal.
• Disconnect the walk-in actuator (RH) connector.
• Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
• Is the connector normal?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the connector, then go to Step 7.

|
INSPECT REAR ONE-TOUCH WALK-IN CONTROL MODULE CONNECTOR CONDITION
• Disconnect the rear one-touch walk-in control module connector.
• Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
• Is the connector normal?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the connector, then go to Step 7.

INSPECT WALK-IN ACTUATOR (RH) CIRCUIT FOR SHORT TO POWER SUPPLY
• Verify that the walk-in actuator (RH) (L.H.D.) and rear one-touch walk-in control module connectors are disconnected.
• Connect the negative battery terminal.
• Switch the ignition ON (engine off or on).
• Measure the voltage at the following terminals (wiring harness-side):
• Is the voltage 0 V?
|
Yes
|
Go to the next step.
|
No
|
Refer to the wiring diagram and verify whether or not there is a common connector between the following circuits:
• L.H.D.
• R.H.D.
If there is a common connector:
• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.
• Repair or replace the malfunctioning part.
If there is no common connector:
• Repair or replace the wiring harness which has a short to power supply.
Go to Step 7.

|
INSPECT WALK-IN ACTUATOR (RH)
• Inspect the walk-in actuator (RH).
(See WALK-IN ACTUATOR INSPECTION.)
• Is the walk-in actuator (RH) normal?
|
Yes
|
Go to the next step.
|
No
|
Replace the second-row seat (RH), then go to the Step 7.
|
||
6
|
INSPECT REAR ONE-TOUCH WALK-IN CONTROL MODULE
• Inspect the rear one-touch walk-in control module.
• Is the rear one-touch walk-in control module normal?
|
Yes
|
Go to the next step.
|
No
|
Replace the rear one-touch walk-in control module, then go to the next step.

|
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
• Reconnect all the disconnected connectors with the negative battery terminal disconnected.
• Connect the negative battery terminal.
• Clear the DTC for the rear one-touch walk-in control module using the M-MDS.
• Retrieve the rear one-touch walk-in control module DTCs using the M-MDS.
• Is the same DTC displayed?
|
Yes
|
Repeat the inspection from Step 1.
• If the malfunction recurs, replace the rear one-touch walk-in control module.
Go to the next step.
|
No
|
Go to the next step.
