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 consult the present input/out value of IPM,
"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"
