Memory Systems - Easy Entry Function Intermittently Inoperative

494

48 Easy Entry function of the power adjustable steering column intermittently does not work

48 13 43

2015819/6

April 19, 2013

Supersedes Technical Service Bulletin Group 48 number 11-15 dated January 10, 2011 for reasons listed below.

Vehicle Information

Condition

The customer may report that the Easy Entry function of the power adjustable steering column intermittently does not work.

Technical Background

The Easy Entry system is a standard convenience function of the power adjustable steering column. When the Easy Entry feature is turned on (Figure

1, B pressed in), the steering column moves to the parked position after the ignition has been turned off and the key has been removed. The parked

position provides more room between the driver and the steering wheel. When the ignition is turned back on, the steering column returns to the last

stored position.

The steering column's position is stored in the memory of the vehicle electrical system control unit, J519 (address word 09).

The seat memory (optional equipment) also stores the steering column's position in the memory seat / steering column adjustment control unit, J316

(address word 36), and is independent of the vehicle electrical system control unit.

During the Easy Entry process, the driver may unknowingly influence the last stored driving position in four different ways:

495

^ If the driver inadvertently touches or bumps the adjustment knob (Figure 1, A) and moves the steering column when exiting or entering the

vehicle, the new position is then stored as the last driving position in the vehicle electrical system control unit. The next time the ignition is

switched on, the steering column will only change position slightly or not at all, appearing as if the Easy Entry position was the last known

driving position.

^ After removing the key from the ignition switch, the customer operates one of the electrical system components (the radio, for example) when the

electrical bus systems have entered sleep mode. When the electrical bus systems are awoken without the ignition switch turned on, the current

position of the steering column is then stored as the new driving position before the electrical bus systems return to sleep mode.

^ The memory may be lost due to the battery not being completely charged (vehicle parked fora long period, aging battery, etc.).

^ If the vehicle is aging and has a weak battery, convenience functions are switched off when more power is needed to ensure that the engine starts

correctly. The Easy Entry function will appear to not function.

Production Solution

Not applicable.

Service

Instruct the customer to re-program the desired position of the steering column or to use the seat memory button (if available) to return the steering

column to the memorized position.

The position selected with the seat memory button is automatically stored in the vehicle electrical system control unit.
