TroubleshootingStep Action Yes No 1 Combination meter power and ground circuit check
1) Turn ignition switch to ON position.
Do warning lights in combi nation meter other than key
indicator lamp light up? Go to Step 2. Check main fuse, circuit
fuse, combination meter
power and ground
circuit.
2 Keyless start control module power and ground circuit
check
1) Check keyless start control module power and ground
circuit for condition referrin g to “Keyless Start Control
Module Power and Ground Circuit Check”.
Is it in good condition? Go to Step 3. Repair circuit.
3 Steering lock unit ignition knob switch check
1) Check ignition knob switch of steering lock unit for
operation referring to “Steering Lock Unit Inspection”.
Is it in good condition? Go to Step 4. Replace steering lock
unit.
4 Wire harness check
1) Turn ignition switch to OFF position.
2) Disconnect connector from ke yless start control module,
steering lock unit and combination meter.
3) Check for open, short and high resistance in. • Between “G22-2” terminal of steering lock unit connector and “G42-34” terminal of keyless start
control module connector
• Between “G28-7” terminal of combination meter connector and “G42-19” terminal of keyless start
control module connector
• Between “G28-9” terminal of combination meter connector and “G42-18” terminal of keyless start
control module connector
Is it in good condition? Go to Step 5. Repair circuit.
5 Keyless start system operation check
1) With remote controller of which ID code is registered in
keyless start control module carried with you, try to turn
ignition knob switch.
Can it be turned to any position other than “LOCK” position? Replace combination
meter.
Substitute a known-
good keyless start
control module and
recheck.
