Fault symptom
Direction indicators do not function when alarm is tripped
|
1.
|
Check that the normal indicator function works by turning on the hazard flashers.
If the hazard flashers do not function, proceed with fault diagnosis in Service Manual 3:5 Electrical system, section "Fault diagnosis ICE".
|
|
2.
|
Connect ISAT and select "ACTIVATE", then "FLASHERS". Activate the flashers with "ON".
The flashers should glow steady.
|
|
3.
|
If not, select "READ VALUES" on the ISAT menu (leave "activate" function "ON") and then select "RELAY, FLASHERS". Read off the display.
When flashers are activated -
"ACTIVE"
If not correct, proceed to step 5.

If function is correct in step 3, check the wiring harness for open circuit/short-circuit to ground by measuring resistance between:
|
|
|
•
|
control module connection pin 12 and connections for left direction indicators.
|
|
|
•
|
control module connector pin 25 and connections for the right direction indicators. The resistance must be < 1 Ohm.
