Mitsubishi Outlander XL. Manual — part 645

STEP 9. Charging system check
Refer to GROUP 16a - Charging System P.16a-8.

Q:Is the charging system in good condition?

YES:

Go to Step 10.

NO:

Repair or replace the charging system component(s).

STEP 10. Retest the system.

Q:Is the communication with scan tool possible?

YES:

An intermittent malfunction may be present. (Refer

to GROUP 00 - How to Cope with Intermittent
Malfunction P.00-15.)

NO:

Make sure that the M.U.T.-III cable is properly

connected and the V.C.I. switch is ON, and then replace
ABS-ECU.

ANTI-LOCK BRAKING SYSTEM (ABS) DIAGNOSIS

2.

System shutdown by ECU
While ABS-ECU is disabled by the diagnostic
function, the scan tool displayed data is different
from the actual measurement.

ACTUATOR TEST REFERENCE TABLE

M13502000116USA0000010000

Using scan tool, the following actuators can be forcibly
operated:

NOTE:

｠

ABS is operated by ABS-ECU.

｠

When ABS-ECU is disabled due to the fail-safe
function, the actuator test cannot be performed.

｠

The actuator test can be performed only when the
vehicle is stationary.

｠

While the actuator test is performed, the ABS
warning light flashes at a rate of 2 Hz.

｠

After the actuator test has been performed, the
brake warning light and ABS warning light illuminate
until the ignition switch is turned to ON again or the
communication between scan tool and ABS-ECU is
terminated.
