HOW TO READ AND ERASE DIAGNOSTIC
TROUBLE CODES
Required Special Tools:
: Diagnostic Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.)
MB991827: MUT-III USB Cable
MB991910: MUT-III Main Harness A (Vehicles with CAN
communication system)
To prevent damage to diagnostic tool , always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting diagnostic tool .
NOTE: If the battery voltage is low, diagnostic trouble codes will
not be output. Check the battery if diagnostic tool does not dis-
play.
1. Connect the diagnostic tool to the data link connector.
2. Turn the ignition switch to the "ON" position.
3. Select "Interactive Diagnosis" from the start-up screen.
4. Select "System Select."
5. Choose "AUTO A/C" from the "BODY" tab.
6. Select "MITSUBISHI."
7. Select "Diagnostic Trouble Code."
8. If a DTC is set, it is shown.
9. Choose "Erase DTC" to erase the DTC.

STEP 6. Check the air mixing damper control motor and
potentiometer.
Do not apply battery voltage when the damper is in the
MAX COOL or MAX HOT position.
(1) Operate the air mixing damper control motor as described
in the table below.
(2) Measure the resistances between connector terminals 3
and 5, and between 3 and 7, while the air mixing damper
control motor is running. The resistances should change
gradually within the standard value.
Standard value: 1.7 (MAX HOT)
5.0 (MAX COOL)

Q: Are the air mixing damper control motor and
potentiometer in good condition?
YES : Replace the A/C-ECU. Then go to Step 7.
NO : Replace the air mixing damper control motor and
potentiometer. Then go to Step 7. LEVER POSITION BATTERY
