Inspection
1. INSPECT FRONT DIFFERENTIAL (a) Using a dial indicator, measure the backlash of one pinion gear while holding the front differential side gear toward the case. Standard backlash: 0.05 - 0.20 mm (0.0020 - 0.0079 in.) NOTICE: Do not mount the surface of front differential case which cont ...

Initialization
1. RESET When the back door lock is replaced: The power back door ECU cannot receive a switch signal from the lock. This may cause the power back door system to enter fail-safe mode and DTC B2215 to set, and also make the system disabled. When the lock is replaced, be sure to perform t ...
