"service column lock" test/procedures per identifix.com
Hey All,
Finished installing my SLP Blackwing CAI on my newly puchased 2001 yesterday and when I went to crank her up I got the dreaded "service column lock" message...crept her back into the garage an ordered the LMC5 this morning.A coworker owns an Aamco and he looked up the tests/procedures on his identifix.com website he uses. Here are 2 procedures that 2 techs had used:
1) Confirm campaign 04006C has been done by calling a dealer with the VIN.
2) If it has been done, locate the relay added during the campaign under the left side of the dash. It should be cable tied to the support brace.
3) Backprobe the light green wire and test the voltage. It should be between 0 and 12 volts as the ignition key lock cyclinder is cycled from RUN to OFF and the ignition key is removed. It should change again as the ignition is cycled from OFF to RUN.
4) If the voltage is fixed at 0 or 12 volts disconnect the added relay.
5) Connect a bulb style test light between the white wire and the purple wire on the Body Control Module (BCM) side of the connector.
6) Cycle the ignition to RUN and then to OFF and remove the ignition key. The test light should light for a couple seconds and then go out when turned to RUN and again when turned to OFF and removing the key.
7) If the light does not light for both positions, disconnect the BCM fuse "25" for 30 seconds and then retest.
8) If the test light now lights in both positions, the BCM was in "standby mode"
---------------------------------------------------------------------
The other test procedure is as follows:
Refer to #04006C (2/8/2006)
1) If there are no open recalls, access the column lock actuator on the steering column. Check for only 2 wires and check for a relay that would be ADDED. This will confirm the relay has been done. perform diagnostics at the relay and NOT the actuator.
2) Access the green wire and check for 12 volts using a DVOM. The wire should get grounded when the key is turned on. Remove the key and check for high voltage on the dark green wire.
3) If the green wire does not get grounded, replace the relay(if the recall has been performed)
4) It is a good idea to check the motor drive circuits coming from the BCM. If the motor drive circuits do not operate correctly, the recall WILL NOT BE AN EFFECTIVE REPAIR.Install a volt meter across the 2 motor drive circuits,white wire and the purple wire, and check for reverse polarity when the key is turned on and the key is removed. This will confirm that the BCM and the factory column lock relay motor drive circuits are OK. If the white and purple wires do not change polarity, verify the BCM has reverse polarity leaving the BCM on the motor drive circuits.
I don't know if this info is already out there but if it's not hope this helps in your troubleshooting....maybe all I'll need is a cheap relay from Pep Boys ???
