DIAGNOSIS SYSTEM (AWD CONTROL UNIT)

CONSULT Function

INFOID:0000000010288267

FUNCTION

CONSULT can display each diagnostic item using the diagnostic test modes shown following.

SELF-DIAG RESULT MODE

Drive at 30 km/h or more for approximately 1 minute before performing the self-diagnosis.

Display Item List

How to Erase Self-Diagnostic Results

Before erasing DTC memory, start the engine and drive at 30 km/h or more for approximately 1 minute. Check
that ABS warning lamp turns OFF.
NOTE:
Make sure that ABS warning lamp turns OFF by driving for a minute at vehicle speed of 30 km/h (19 MPH) or
more after turning ignition switch OFF if AWD warning lamp turns ON with system malfunction of “ABS SYS-
TEM [C1203]”. AWDAWD warning lamp may not turn OFF if it is normal unless ignition switch turns OFF at
once and engine restarts after that.
