5. Is the measured value within specification?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
  - Go to " CHECK SHORT IN SIGNAL CIRCUIT" as follows.
Check short in signal circuit
1. IG key OFF.
2. Disconnect 'CRUISE REMOCON SWITCH' connector and Cluster 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
