VEHICLE STABILITY CONTROL SYSTEM Crawl Indicator Light does not Come ON

DTC Code DTC Name
Crawl Indicator Light does not Come ON

DESCRIPTION

If any of the following conditions are met, the crawl indicator light blinks and crawl control is stopped.

  • Crawl control is operated when the vehicle stability control system is malfunctioning, or a vehicle stability control system malfunction occurs during crawl control.

  • The transfer is shifted to H4 during crawl control.

  • The shift lever is moved to P or N during crawl control.

  • The driver side door is opened during crawl control.

When the vehicle is driven at 25 km/h (16 mph) or more during crawl control, control is temporarily stopped and the crawl indicator light blinks.

When using crawl control continually for a long period of time, if the temperature inside the hydraulic brake booster becomes too high, the crawl indicator light will turn off after blinking. After a while, the temperature decreases and crawl control becomes operable.
