Trouble Diagnostics When Using GDS

1. The IPM can be diagnosed by using the GDS. The BCM communicates with the GDS which then displays inputs and outputs along with codes.
2. To diagnose the IPM function, select the vehicle model and IPM.




3. To view the input/out value of IPM, use the GDS to check "Current DATA". It provides information of IPM input/output conditions of power supply, turn signal/brake lamp, headlamp, door locks, outside mirror, wiper, auto-light and transmitters etc.




4. To perform functional test on IPM outputs, select "Actuation Test"
