TO BATTERY VOLTAGE AT DIFFLOCK OR
AXLE CONNECTION SOLENOID
TCU detected a wrong voltage at the
output pin, that looks like a s.c. to battery
voltage
• cable is defective and is contacted to
battery voltage
•
difflock solenoid has an internal defect
• connector pin is contacted to battery
voltage
no reaction
OP-mode: normal
• check the cable from TCU to the
difflock solenoid
• check the connectors from difflock
solenoid to TCU
•
check the resistance
