STEP 5. Check transfer-ECU connector E-109 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Are the connector and terminals in good condition?

YES : Go to Step 6.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E, Harness Connector Inspection 

P.00E-2

.

STEP 6. Using scan tool MB991958, check data list item 09: 
Ignition switch power supply.

CAUTION

To prevent damage to scan tool MB991958, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991958 to data reading mode.

• Item 09: Ignition Switch Power Supply.

• The voltage should equal battery positive voltage.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage equal battery positive voltage?

YES : It can be assumed that this malfunction is intermittent. 

Refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points 

− How to 

Cope with Intermittent Malfunction 

P.00-6

.

NO :  Replace the transfer-ECU.

DTC 13: Main Relay System (Inside of ECU)

.

CIRCUIT OPERATION
The power supplied from the ignition switch is distrib-
uted to each part of ECU through the main relay 
located inside of ECU.

.

DTC SET CONDITIONS
When the voltage at main relay OFF is 6 volts and 
over, or the voltage at main relay ON is 6 volts and 
less, the DTC 13 is set as the main relay malfunction.

TROUBLESHOOTING HINTS (THE MOST LIKELY 
CAUSES FOR THIS CODE TO BE SET:)

• Malfunction of the transfer-ECU

DIAGNOSIS

Replace the transfer-ECU.
Q: Is the malfunction eliminated?

YES : The procedure is complete (If no malfunction is not 

found an intermittent malfunction is suspected. Refer 
to GROUP 00, How to Use

DTC 21: Accelerator Pedal Position Sensor System

AC205258AB

Accelrator Pedal Position Sensor System Circuit

TRANSFER DIAGNOSIS <ACTIVE TRAC AWD II>

TSB Revision

AUTOMATIC TRANSMISSION

23A-410

.

CIRCUIT OPERATION

• When the throttle valve shaft rotates from the idle 

position to the fully opened position, the resis-
tance between the accelerator pedal position 
sensor output terminal (terminal 6) and ground 
terminal (terminal 7) will increase according to 
the rotation.

• With the ignition switch in the "ON" position. Volt-

age at pin 5 increases from approximately 0.7 
volt at closed throttle, to approximately 5 volts at 
wide open throttle.
