-------------------------------------------------
Checking the antenna ring
- Ignition off.
- Disconnect the antenna ring.
- Connect an ohmmeter between terminals #1 and #2 on the antenna ring.
The ohmmeter should read approximately 2-4 ohms.
Is the value OK?
OK - Checking the antenna ring circuit
Not OK - Replacing the component
-------------------------------------------------
Checking the antenna ring circuit
- Ignition off.
- Connect breakout box 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 Connecting the Breakout Box.
- Disconnect the immobilizer control module.
Connect an ohmmeter between breakout box terminal #55 (terminal #9) and antenna ring terminal #2.
Connect an ohmmeter between breakout box terminal #56 (terminal #10) and antenna ring terminal #4.
The ohmmeter should read approximately 0ohms for both measurements.
OK - Checking for short-circuits to supply voltage
Not OK - Checking for an open-circuit
-------------------------------------------------
Replacing the component
Try a new antenna ring according to Replacing ignition switch antenna ring Service and Repair.
Select Continue.
Continue - Verification
-------------------------------------------------
Checking for short-circuits to supply voltage
- Ignition off.
- Immobilizer control module disabled.
Connect a voltmeter between breakout box terminals #55 (terminal #9) and #54 (terminal #8).
- Make a note of the voltmeter reading.
Connect a voltmeter between breakout box terminals #56 (terminal #10) and #54 (terminal #8).
- Make a note of the voltmeter reading.
- Ignition on.
- Repeat the readings as above.
- Make a note of the readings.
The voltmeter should read 0 V for both readings.
OK - Checking for short-circuits to ground
Not OK - Checking for short-circuits to supply voltage
-------------------------------------------------
Checking for an open-circuit
Check the relevant antenna ring cable 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
-------------------------------------------------
Checking for short-circuits to ground
- Ignition off.
- Immobilizer control module disabled.
Connect an ohmmeter between breakout box terminals #55 (terminal #9) and #54 (terminal #8).
Connect an ohmmeter between breakout box terminals #56 (terminal #10) and #54 (terminal #8).
In both cases the ohmmeter should read infinite resistance.
OK - Replacing the component
Not OK - Checking for short-circuits to ground
-------------------------------------------------
Checking for short-circuits to supply voltage
If the value was higher than 0 when taking a reading on #55 (#9), check the cable between immobilizer control module #9 and antenna ring #2 for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.
If the value was higher than 0 when taking a reading at terminal #56 (terminal #10), check the cable between immobilizer control module terminal #10 and antenna ring terminal #4 for a 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.
