DIAGNOSTIC FUNCTION
When the liftgate sensor (RH) open circuit is detected, the power liftgate control unit sets DTC No. B2484.
 
 
JUDGMENT CRITERIA
When the liftgate sensor (RH) open circuit is detected, the power liftgate control unit sets DTC No. B2484.
 
 
PROBABLE CAUSES
  • Damaged wiring harness and connectors
  • liftgate sensor (RH) malfunction
  • Malfunction of the power liftgate control unit
 
 
DIAGNOSIS
Required Special Tools:
  • MB991223: Harness Set
  • MB992006: Extra Fine Probe
STEP 1. Liftgate sensor (RH) check.
Check theliftgate sensor (RH) (refer to ).
Is the check result normal?
Go to Step 2.
Replace the liftgate sensor (RH).
 
STEP 2. Resistance measurement at liftgate sensor (RH) connector (ground line terminal).
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the resistance between the liftgate sensor (RH) connector (ground line terminal) and body ground.
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 power liftgate control unit connector and liftgate sensor (RH) connector.
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 power liftgate control unit connector and liftgate sensor (RH) connector.
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness.
 
STEP 5. Check whether the diagnostic trouble code is set again.
(1) Clear all the DTC set in the power liftgate control unit.
(2) Operate the power liftgate.
(3) Check whether a DTC is set in the power liftgate control unit.
Is the DTC set?
Replace the power liftgate control unit.
The diagnosis is complete.
