Checking permanent/intermittent fault
- Switch ignition on and off at least three times with three seconds interval.
Read DTCs.
Is diagnostic trouble code (DTC) IMM-336 still stored?
Yes - Checking VGLA output
No - Fault-tracing information
-------------------------------------------------
Checking VGLA output
- Ignition on.
Read off the VGLA OUTPUT parameter.
Does VGLA OUTPUT display LOW?
Yes - Connect breakout box
No - Checking for a short-circuit to supply voltage
-------------------------------------------------
Connect breakout box
- Ignition off.
- Remove immobilizer control module according to Replacing immobilizer control module Replacing Immobilizer Control Module.
- Connect adapter 981 3194 Replaced by 9511495 981 3194 Replaced by 951 1495 and breakout box 981 3190 Replaced by 9511428 981 3190 Replaced by 951 1428 according to Connecting the breakout box, Immobilizer Connecting the Breakout Box.
Continue - Checking VGLA circuit
-------------------------------------------------
Checking for a short-circuit to supply voltage
Check the cable between immobilizer control module #7 and VGLA control module #B:9 for short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Select Continue when the fault has been remedied.
Continue - Verification
-------------------------------------------------
Checking VGLA circuit
- VGLA control module connector A disconnected.
- Immobilizer control module disconnected.
Connect an ohmmeter between breakout box #53(#7) and ground.
The ohmmeter should read infinite resistance!
OK - Checking for an open-circuit
Not OK - Checking for a short-circuit to ground
-------------------------------------------------
Checking for a short-circuit to ground
Check the cable between immobilizer control module #7 and VGLA control module #B:9 for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Select Continue when the fault has been remedied.
Continue - Verification
-------------------------------------------------
Checking for an open-circuit
Check the cable between immobilizer control module #7 and VGLA control module #B:9 for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Select Continue when the fault has been remedied.
Continue - Verification

Verification
Hint: After finishing the repair check that the repair is successful and that the fault is corrected as follows.
- Ignition on.
Erase diagnostic trouble codes (DTCs).
Continue - Verification (continued)
------------------------
Verification (continued)
- Switch off the ignition for at least 3 seconds.
- Ignition on.
Read off diagnostic trouble codes (DTCs).
Has the diagnostic trouble code (DTC) been stored again?
Yes - VERIFICATION FAILED
No - VERIFIED

VERIFIED - FAULT FOUND
VERIFICATION FAILED - Fault-tracing information
-------------------------------------------------
Fault-tracing information
Information
Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - Exit fault-tracing
No - Attempt New Test

Fault-tracing information
Information
Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
Do you want to view the information again?
Yes - Attempt New Test
No - FAULT FOUND
