JUDGMENT CRITERIA
When the tailgate sensor (RH) open circuit is detected, the electric tailgate control
unit sets diagnosis code No. B2484.
PROBABLE CAUSES
- Damaged wiring harness and connectors
- Tailgate sensor (RH) malfunction
- Malfunction of the electric tailgate control unit
DIAGNOSIS PROCEDURE
STEP 1. Tailgate sensor (RH) check.
Check the tailgate sensor (RH) (refer to
).
Q.
Is the check result normal?
Go to Step 2.
Replace the tailgate sensor (RH).
STEP 2. Resistance measurement at tailgate sensor (RH) connector (earth
line terminal).
|
(1)Disconnect the connector, and measure at the wiring harness side.
|
|
(2)Measure the resistance between the tailgate sensor (RH) connector (earth line terminal)
and body earth. OK: Continuity exists (2 Ω or less)
|

Is the check result normal?
Go to Step 4.
Go to Step 3.
STEP 3. Check of open circuit in TSG line between electric tailgate
control unit connector and tailgate sensor (RH) connector.
Q.
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness.
STEP 4. Check of open circuit in TSR line between electric tailgate
control unit connector and tailgate sensor (RH) connector.
Q.
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness.
STEP 5. Diagnosis code recheck
|
(1)Clear all the diagnosis codes stored in the electric tailgate control unit.
|
|
(2)Operate the electric tailgate.
