The cruise control brake switch is a normally closed switch. When the cruise control brake switch is closed, the powertrain control module (PCM) senses the ignition voltage on the cruise control brake switch signal circuit.
The number(s) below refer to the step number(s) on the diagnostic table.
This step determines if the fault is present.
This step checks for a cruise control brake switch circuit for being shorted to B+.
Step | Action | Value(s) | Yes | No |
---|---|---|---|---|
1 | Was the On-Board Diagnostic (OBD) System Check performed? | -- | ||
Does the display indicate Applied? | -- | Go to Symptoms | ||
Does the display indicate Applied? | -- | |||
4 |
Is the voltage greater than the specified value? | 0.5 V | ||
5 | Repair the short to voltage on the cruise control brake switch signal circuit? Is the action complete? | -- | -- | |
6 | Replace the cruise control brake travel switch. Is the action complete? | -- | -- | |
7 | Replace the PCM. The replacement PCM must be programmed. Is the action complete? | -- | -- | |
8 | Operate the vehicle within the conditions under which he original symptom was noted. Does the system now operate properly? | -- | System OK |
