10C-10 Immobilizer Control System:
4 Check for open and high resistance in CAN
communication wire circuits between ABS/ESP
®
control module and keyless start control module
1) Disconnect connector “E03” from ABS control module or
“E53” from ESP
®
control module.
2) Disconnect connector “G42” from keyless start control
module.
3) Measure resistance at the following wire terminals.
Vehicle equipped without ESP
®
control module
• Between “E03-12” wire terminal at ABS connector
and “G42-19” wire terminal at keyless start control
module connector
• Between “E03-6” wire terminal at ABS connector and
“G42-18” wire terminal at keyless start control module
connector
Vehicle equipped with ESP
®
control module
• Between “E53-13” wire terminal at ESP
®
control
module connector and “G42-19” wire terminal at
keyless start control module connector
• Between “E53-44” wire terminal at ESP
®
control
module connector and “G42-18” wire terminal at
keyless start control module connector
Is each resistance 1
Ω
or less?
Go to Step 5. Repair open or high
resistance in
malfunctional wire
circuit.
5 Check for short between CAN communication wire
circuits between ABS/ESP
®
control module and keyless
start control module
1) Disconnect connector “G31” from BCM connector.
2) Disconnect connector “G28” from combination meter.
3) Measure resistance at the following wire terminals.
Vehicle equipped without ESP
®
control module
• Between “E03-12” wire terminal at ABS control
module connector and “G42-18” wire terminal at
keyless start control module connector.
Vehicle equipped with ESP
®
system
• Between “E53-13” wire terminal at ESP
®
control
module connector and “G42-18” wire terminal at
keyless start control module connector
Is resistance infinite?
Go to Step 6. Repair short between
CAN communication
wire circuits.
6 Check for short to ground wire circuit in CAN
communication wire circuits
1) Measure resistance at the following wire terminals.
Vehicle equipped without ESP
®
system
• Between “E03-6” wire terminal at ABS control module
connector and body ground
• Between “E03-12” wire terminal at ABS control
module connector and body ground
Vehicle equipped with ESP
®
system
• Between “E53-13” wire terminal at ESP
®
control
module connector and body ground
• Between “E53-44” wire terminal at ESP
®
control
module connector and body ground
Is resistance infinite?
Go to Step 7. Repair short to ground
wire circuit in CAN
communication wire
circuits.
