5. Is the measured value within specification?
  YES
  - Go to COMPONENT INSPECTION .
  NO
  - Go to 2.
Check short in signal circuit
1. IG key OFF.
2. Disconnect 'CRUISE REMOCON SWITCH' connector and PCM connector.
3. Check resistance between 'Signal (Cruise sw)' terminal and 'CRUISE MAIN' terminal of 'CRUISE REMOCON SWITCH' harness connector.
4. Check resistance between 'Signal (Cruise sw)' terminal and 'Ground (Cruise sw)' terminal of 'CRUISE REMOCON SWITCH' harness connector.
  Specification: Infinite

5. Is the measured value within specification?
  YES
  - Go to 3.
  NO
  - Repair short in signal circuit, and go to VERIFICATION OF VEHICLE REPAIR .
Check open in signal circuit
1. IG key OFF.
2. Disconnect 'CRUISE REMOCON SWITCH' connector and PCM connector.
3. Measure resistance between 'Signal (Cruise sw)' terminal of 'CRUISE REMOCON SWITCH' harness connector and 'Signal (Cruise sw)' terminal of PCM connector.
  Specification: Below 1.0 Ω
