F2 SELF-DIAGNOSlS FUNCTION
Troubleshooting
If a malfunction code number is shown on the SST (49 l-l01 8 9Ai, 49 B019 9AO), check for the cause
using the chart related to the code number shown, [Regarding code numbers except 05, 24, and 42, refer
to “Troubleshooting” in Workshop Manual [I 203-I O-89F (Europe) or 1204-f 0-89F (Australia)].

Check knock sensor and knock control unit
circuit for poor connectlon ACTtON
Yes Repalr or replace connector
Check knock control unit terminal voltage with
ignition switch ON
Check that voltage at ECU terminal 2J is
approx. 4V at idle
rs7 page F2-64 Yes Recheck ECU connector for poor
connection
4 If OK, replace ECU
4 If not OK, repair or replace connector
NO Repair wiring harness (R/Y) between
ECU terminal 2J and knock control unit
