Circuit Description
The instrument panel cluster (IPC) turns the LOW TRAC indicator on during the IPC bulb check for approximately 3 seconds when the ignition switch is turned to the ON position. The LOW TRAC Indicator is activated during a traction control event only. If the EBCM detects a low traction condition, the EBCM sends the IPC the command to turn the LOW TRAC Indicator on.
