Known issuesShift lever position indicator in the instrument cluster may not illuminate (FMVSS 102) - recall 05V-0552
Recall2005 GMC YUKON XL ・ —
Automatic Transmission Shift Lever Position Indicator Illumination Recall
1Fault
- Under certain starting conditions the shift lever position indicator in the instrument panel cluster may not illuminate; on later start-ups the condition may or may not recur.
- If the indicator does not illuminate, the driver may not know which gear is selected and the vehicle may move in an unintended direction, possibly injuring people outside the vehicle.
2Finding the cause
Possible causes
- The PRNDL indicator behavior is induced only by a very specific battery voltage waveform and depends on vehicle level characteristics, while the vehicle otherwise operates normally.
- The "blank PRNDL" anomaly appeared at the assembly plants after interim 2005 model year instrument panel cluster revisions that began on January 31, 2005.
3Correction
Repair
- Dealers are to reprogram the instrument panel cluster.
- Prepare the vehicle for instrument panel cluster (IPC) reprogramming, then program the IPC using TIS data version 2.25.
Parts
- No parts are required for this recall.
Caution
- The service calibration is in Techline Information System (TIS) data version 2.25 and on TIS CD-ROM version 3.
- A later dealer message says TIS Data 2.50 has been released, so dealers no longer need to contact the Techline Customer Support Center (TCSC) for a VCI number to access the calibration.
- Vehicles with manual transmissions are not involved in this recall and need no further action.

Normal Transmission Shift and Throttle Response Delay
1Fault
- A sag or hesitation may be noticed when coasting at low speeds of less than 24 km/h (15 mph) with a closed throttle and then aggressively applying the throttle.
- With an automatic transmission, after a hard complete stop with a closed throttle immediately followed by an aggressive throttle opening, the downshifts may not be completed by the time the throttle is opened.
- A sag or hesitation may also be noticed while cruising at highway speeds and then aggressively increasing the throttle, forcing a down-shift.
2Finding the cause
Possible causes
- In this maneuver the throttle blade is opened slowly for up to 0.7 seconds, even though the accelerator is applied aggressively, to help minimize driveline lash and clunking.
- As a result, approximately 0.5 seconds of zero torque may be commanded to allow the shift to first gear to occur.
3Correction
Caution
- All of these conditions are a result of Torque Management and should be considered normal; no repairs should be attempted.

Aftermarket ALDL/DLC Interface Devices - Diagnostic Concerns
1Fault
- Gauge or instrument fault
- Warning light
- C0561 (general documents only)
- U0100 (general documents only)
- U0101 (general documents only)
- U186B (general documents only)
- U1862 (general documents only)
- The radio may not shut off after the vehicle is shut down, and bus or LAN traffic may stay active, leading to a discharged battery.
- C0561 may be stored in the EBCM, leading to a traction control issue, and there may be no high speed LAN communication with various communication U-codes.
- The SES, MIL or CEL light may be set with numerous communication DTCs such as U0100, U0101, U186B and U1862.
- The transmission may not shift for one key cycle (TCM in default mode), and gauge readings may be erratic or displays may flicker.
2Finding the cause
Possible causes
- Monitoring devices and other electronic accessories such as aftermarket cruise control or police speed checking devices (RADAR or LIDAR) may cause one or more of the listed concerns.
- Many of the problems could be caused by an open connection on the HSCAN bus: a device that connects to only one CAN + causes bus errors and erratic ECU behavior.
Steps to confirm (in the document’s order)
- If normal diagnostics find no root cause, check for a device plugged into the ALDL or Data Link Connector (DLC) for tracking and/or maintenance interval scheduling.
3Correction
Repair
- If SI diagnostics do not identify the source and the device is available, try to duplicate the condition, then remove the device to see whether the condition is eliminated.
- If removing the DLC interface device resolves the concern, tell the customer the result and that they should work with the device's supplier for further resolution.
Caution
- The customer may remove the device for use in another vehicle while theirs is in for service.
- Some devices carry a second DLC connector, with the device and the rest of the harness hidden out of sight, so the technician may not notice that the diagnostic connector is not in the factory location.
