Circuit/System Testing
- Ignition OFF, disconnect the cruise control switch assembly.
- Connect a fused jumper between the voltage signal circuit and the low reference circuit.
- Ignition ON, observe the Cruise On/Off Switch parameter.
⇒ | If the Cruise On/Off Switch parameter displays ON, replace the cruise control switch assembly. |
⇒ | If the Cruise On/Off Switch parameter displays Off, test the voltage signal circuit and the low reference circuit for
an open, or for a high resistance. |
- If all circuits test normal, replace the BCM.
