1998 HONDA CR-V Ac system

NOTE: When the OBD ll Scan Tool or Honda PGM Tester indicate DTC(S) for the automatic transmission control system,
the scan tool or tester indicates code P0700 simultaneously. Code P0700 means a detection of some automatic transmis-
sion problem in the PGM-Fl control system.
lf the self-diagnostic E or E indicator light does not blink, perform an inspection according to the table below.
NOTE: lf a customer describes the symptom for code P17OO (6), it will be necessary to recreate the symptom by test-driv-
ing. then recheck the DTC.
