1
Was “4WD control system check” performed?
Go to Step 2.
Go to “4WD Control
System Check”.
2
CPP switch circuit check
1) Disconnect CPP switch connector with ignition switch
OFF.
2) Check for proper connection to terminal of CPP switch
connector.
3) If connection is OK, measure voltage between “BLK/
ORN” terminal of CPP switch connector and vehicle
body ground with ignition switch ON.
Is it 10 – 14 V?
Go to Step 3.
Go to Step 4.
3
CPP switch check
1) Check CPP switch referring to “Clutch Pedal Position
(CPP) Switch Inspection and Adjustment in Section 5C”.
Is switch in good condition?
Substitute a known-
good 4WD control
module and recheck.
Replace CPP switch.
4
Wire harness check
1) Disconnect connector from 4WD control module
connector “E91” with ignition switch OFF.
2) Check for proper connection to “E91-7” terminal of 4WD
control module connector.
3) If OK, measure resistance between “BLK/ORN” terminal
of CPP switch connector and “E91-7” terminal of 4WD
control module connector.
Is it 1 M
Ω
or more?
Substitute a known-
good 4WD control
module and recheck.
“BLK/ORN” wire is
shorted to ground
circuit.

1
Was “4WD control system check” performed?
Go to Step 2.
Go to “4WD Control
System Check”.
2
Control module connector check
1) Check connection of connectors of all control modules
communicating by means of CAN.
2) Recheck DTC in TCM.
Is DTC U1073 detected?
Go to Step 3.
Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
3
CAN communication circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connectors of all control modules
communicating by means of CAN.
3) Check CAN communication circuit between control
modules for open, short and high resistance.
Is each CAN communication circuit in good condition?
Go to Step 4.
Repair circuit.
4
Check DTC
1) Turn ignition switch to OFF position.
2) Disconnect each connector.
• ECM
• ABS or ESP
® hydraulic unit / control module
• BCM
• TCM (if equipped)
• Keyless start control module (if equipped)
3) Recheck DTC in 4WD control module.
Is DTC U1073 detected?
Check 4WD control
module power and
ground circuit. If circuits
are OK, substitute a
known-good 4WD
control module and
recheck.
Check applicable
control module power
and ground circuit. If
circuit is OK, substitute
a known-good
