DTC 6

DTC 6: STOP LAMP SWITCH OPEN CIRCUIT OR SHORT

Circuit Description
The brake switch is used to indicate brake pedal status. The normally opened brake switch signal voltage circuit is opened.
Brake switch supplies a B+ signal on circuit RED to the control unit when the brakes are applied. The control unit uses this signal to work drive control when the brakes are applied.

Diagnostic Aids
- Inspect the wiring for poor electrical connections between the control unit and the brake switch. Look for possible bent, backed out, deformed, or damaged terminals. Check for weak terminal tension as well.
Also check for a chafed wire that could short to bare metal or other wiring. Inspect for a broken wire inside the insulation.
- When diagnosing for a possible intermittent short or open condition, move the wiring harness while observing test equipment for a change.
- Check customer driving habits and/or unusual driving conditions (i.e. stop and go, highway).
- Check brake switch for proper mounting and adjustment.
