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
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
.
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
Troubleshooting/Inspection Service Points
− How to
Cope with Intermittent Malfunction
).
NO : Replace the PCM.
DTC 21: Accelerator Pedal Position Sensor System
AC205258AB
Accelrator Pedal Position Sensor System Circuit
TRANSFER DIAGNOSIS <ACTIVE TRAC AWD II>

.
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.
