DIAGNOSTIC FUNCTION
When the full latch switch signal of liftgate latch is not detected, the power liftgate control unit sets DTC No. B2483.
 
 
JUDGMENT CRITERIA
During the power liftgate close operation, if the signal of liftgate latch full latch switch is not detected consecutively for five times, the power liftgate control unit sets DTC No. B2483.
 
 
PROBABLE CAUSES
  • Damaged wiring harness and connectors
  • Malfunction of the power liftgate control unit
  • Malfunction of liftgate latch
 
 
DIAGNOSIS
Required Special Tools:
  • MB991223: Harness Set
  • MB992006: Extra Fine Probe
STEP 1. Full-latch switch check.
Check the liftgate latch (refer to ).
Is the check result normal?
Go to Step 2.
Replace the liftgate latch.
 
STEP 2. Resistance measurement at liftgate latch connector (full-latch switch ground line terminal).
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the resistance between the liftgate latch connector (full-latch switch 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 ground line between liftgate latch connector (full-latch switch terminal) and body ground.
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness.
 
STEP 4. Check of open circuit in FULL line between power liftgate control unit connector and liftgate latch 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 diagnostic trouble codes set in the power liftgate control unit.
(2) Operate the electric liftgate.
(3) Check whether a diagnostic trouble code is set in the power liftgate control unit.
Is the DTC set?
Replace the power liftgate control unit.
The diagnosis is complete.
