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.

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 

P.00E-2

. 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.
Replace the G and yaw rate sensor, and check that the DTC 
sets.
Q: Does the M-ASTC-ECU set DTC 67?

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
