03 CLUTCH RELEASE COMPONENT LUBRICATION

When removing a manual transmission for clutch servicing, it is required that the clutch release components are cleaned, inspected, and lubricated in accordance with the applicable Service Manual. Cleaning the transmission case surrounding the clutch assembly is necessary to prevent debris from contaminating the lubricant and interfering with release bearing operation. Thoroughly inspect the transmission case where the release bearing travels for damage or wear marks which could interfere with release bearing operation. Failure to follow these procedures can result in squeaks, rattles, increased clutch pedal effort, and ultimately an unnecessary comeback. Figure 1  shows the points of lubrication that are critical in preventing noises and ensuring proper operation of the clutch release components.

Below are images labeled 1, 2, 3, and 4 that correspond with Figure 1. Each image shows the required lubrication point in detail. You can use these images as a reference when applying the approved lubricant. To locate the correct lubricant (grease), review the applicable Service Manual and if necessary use Service Bulletin 01-167-08R for approved equivalents.

07 IGNITION KEY CANNOT BE REMOVED FROM IGNITION SWITCH

If you confirm a customer complaint of the ignition key not able to be removed from the ignition switch, check the following PID (Figure 1)  in the Body Integrated Unit  current data display:

Figure 1
Key lock solenoid output	Key lock solenoid output ON/OFF status. Body integrated unit output value. Solenoid is activated to set this item to ON when the key is inserted with the shift lever in other than P range.	Lock/Unlock/	Model without keyless access with push button start system

If the key lock solenoid output  reads as Lock  , the next step in diagnosis should be to inspect the following PID (Figure 2  ):

Figure 2
P SW	P range switch ON/OFF status, Body integrated unit value. Set to ON in the P range.	ON/OFF

P SW  is the park range switch, located in the AT shifter assembly. If the shifter is in the park position and this PID remains OFF  , suspect an issue with the park range switch or circuit. Inspect for drink spills, previous interior repairs, modifications, and shifter position. Troubleshooting procedures can be found in the applicable Service Manual under the AT Shift Lock Control System > KEY INTERLOCK CANNOT BE LOCKED OR RELEASED.

07 REPLACING B-TYPE BIU

The Techline has been receiving calls from Technicians replacing BIUs where the keys cannot be successfully registered. Keep in mind on a B-type system, the BIU and combination meter store key IDs when programmed. These key IDs remain stored and must match when installing a new component to the immobilizer. If the car came with three keys, then the BIU and combination meter will have three key IDs stored. When replacing a BIU, you should collect all the keys from the customer. However, if you did not do that and are looking to program the BIU, you will need to delete the keys from the immobilizer before installing the new BIU. When you program the new BIU you will only need the one key from the ignition which was not deleted, program that key, then when all the original keys are obtained, you can program them. This could also be used if the customer has lost a key and does not want to replace it but wants to repair the car. However, if you run into a scenario where you cannot communicate with the BIU to delete the keys, then you will need to get the original keys that were programmed to the vehicle to successfully finish the programming.

Example 1  : A 2015 Legacy comes in and has BIU failure. You cannot communicate with the BIU  ; the customer has supplied three original keys. Replace the BIU and program the keys.

Example 2  : A 2015 Outback comes in and has been diagnosed with a BIU issue. Communication is normal. The customer only has one key for the car all others were lost. Go into immobilizer and delete all keys. This will delete all except the one in the ignition. Next, install the new BIU and program the only one key you have. Extra keys can be added upon the customer's request.

Example 3  : A 2015 Forester comes in and has been diagnosed as having a faulty BIU. Communication is normal. The customer has supplied all original keys to the Technician. Replace the BIU and program the keys. When replacing a BIU always follow the applicable Service Manual procedure.
