STEP 4. Check the power supply system from the ignition
switch (IG1) to the G and yaw rate sensor. Measure at G
and yaw rate sensor connector E-126.
(1) Disconnect G and yaw rate sensor connector E-126, and
measure the voltage at the harness-side connector.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between G and yaw rate sensor
connector E-126 terminal 1 and body ground.
• The voltage should measure battery voltage (approxi-
mately 12 volts).
Q: Does the voltage measure battery voltage
(approximately 12 volts)?
YES : Go to Step 6.
NO : Go to Step 5.
STEP 5. Check the wiring harness between G and yaw rate
sensor connector E-126 terminal 1 and the ignition switch
(IG1).

NOTE: Also check joint connector D-01 and junction block con-
nector D-208 and D-212 and intermediate connector E-11 for
loose, corroded, or damaged terminals, or terminals pushed
back in the connectors. If joint connector D-01 or junction block
connector D-208 or D-212 or intermediate connector E-11 are
damaged, repair or replace the damaged component(s) as
described in GROUP 00E, Harness Connector Inspection
. If the connector has been repaired or replaced, go to
Step 9.
Q: Is the wiring harness between G and yaw rate sensor
connector E-126 terminal 1 and the ignition switch (IG1)
in good condition?
YES : Go to Step 9.
NO : Repair the wiring harness, and then go to Step 9.

STEP 6. Check G and yaw rate sensor for ground circuit.
Measure at G and yaw rate sensor connector E-126.
(1) Disconnect G and yaw rate sensor connector E-126, and
measure the resistance at the harness-side connector.
(2) Measure the resistance between G and yaw rate sensor
connector E-126 terminal 4 and body ground.
• The resistance should measure 2 ohms or less.
Q: Does the resistance measure 2 ohms or less?
YES : Go to Step 8.
NO : Go to Step 7.
STEP 7. Check the wiring harness between G and yaw rate
sensor connector E-126 terminal 4 and body ground.
Q: Is the wiring harness between G and yaw rate sensor
connector E-126 terminal 4 and the body ground in
good condition?
YES : Go to Step 9.
NO : Repair the wiring harness, and then go to Step 9.
STEP 8. Replace the G and yaw rate sensor (Recheck for
diagnostic trouble code).
Replace the G and yaw rate sensor, and check that the DTC
sets.
Q: Does DTC 67 reset?
YES : Replace the M-ASTC-ECU, and then go to Step 9.
NO : The procedure is complete.
STEP 9. Recheck for diagnostic trouble code.
Q: Does DTC 67 reset?
YES : Return to Step 1.
NO : The procedure is complete.

DTC 75: Defective transfer switch
.
CIRCUIT OPERATION
If the transfer gear is engaged, a relevant switch is
turned on. When the switch is turned on, the current
from the M-ASTC-ECU is grounded.
.
M-ASTC DTC SET CONDITION
DTC 75 is set when the 2WD/4WD detection switch,
the center differential detection switch, the 2WD
detection switch, 4LLc detection switch or the 4H
detection switch or their relevant circuits is defective.
.
TROUBLESHOOTING HINTS
The most likely causes for DTC 75 to set are:
• The 2WD/4WD detection switch is defective.
