Driver Position Memory System (Dpms): Other Honda Odyssey IV

Memorizing a Seat and a Mirrors ('08-10 Touring models) Position

Move the seat and the mirrors to the desired position. Turn the ignition switch ON (II).

Press and hold the MEMO button on the driver's position memory switch. A single beep will be heard and both of the green LEDS will begin to flash. Press No. 1 or No. 2 to match the remote that is to be used. There will be two more beeps confirming that the seat and the mirrors ('08-10 Touring models) positions have been memorized. The LED will remain lit, unless the seat and the mirrors ('08-10 Touring models) are moved from the memorized position.

Memorized Position Recall with the Remotes

Make sure that the remotes are LINKED. Press and hold the LOCK and UNLOCK button at the same time. The red LED on the remote will flash ONE time when the remote has been LINKED and will flash TWO times when the remote has been UNLINKED. After the seat and the mirrors ('08-10 Touring models) positions have been memorized, the seat and the mirrors ('08-10 Touring models) will move to the position when the appropriate remote UNLOCK is pressed and the driver's door is opened. When the seat and mirrors ('08-10 Touring models) get to the memorized position, the green LED corresponding with that remote will stay lit until the position is changed or the key is turned OFF.

Power Seat Position Sensors

Each motor has a sensor that detects motor rotation and sends a pulse to the power seat control unit when the motor rotates. The control unit stores the number of pulses in its memory, and the seat position is memorized.

Power Mirror Position Sensors ('08-10 Touring models)

By means of a tilt position sensor and swing position sensor, the power mirror control circuit in the power mirror control unit detects the voltage changes caused by the movements of the mirrors. These voltage changes are stored in memory, and the power mirror positions are memorized for each stored driving position.

Reverse Mirror Control ('08-10 Touring models)

When the vehicle is shifted to Reverse (shift lever in R position) with the power mirror selector switch in Left (or Right) position, the driver's (or passenger's) side mirror tilts down automatically to help the driver's view. The mirror will return to the previous position when the shift lever is shifted out of R position. The reverse mirror control is cancelled if the power mirror selector switch is in the center position.

Using the HDS (preferred method)

1. Go to B-CAN System Diagnostic Test Mode A to check for "Connected Units" and DTCs (see «TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A»(ref-294731-S03650631412008081300000) ).
2. If no DTCs are retrieved, go to B-CAN System Diagnosis Test Mode C (see «TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE C»(ref-294731-S23548620932008081300000) ) or Test Mode D (see «TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE D»(ref-294731-S37107684632008081300000) ).

Without the HDS (use only if HDS is not available)

The self-diagnostic function of the driving position memory system detects system problems. If a system problem is detected, the buzzer built into the power seat control unit sounds for 5 seconds. This information can be retrieved through the driving position memory switch indicators.

Scheme 22

1. Turn the ignition switch to LOCK (0), and move the seat to a non-memorized position.
2. Press and hold the MEMO button (A) and both position buttons (B) at the same time.
3. Turn the ignition switch to ON (II), and wait at least 1 second, then release the three buttons.
4. After 1 second, the position button indicators (C) will blink to show the DTC.

No System Problem

If there is no DTC stored, the indicators blink only once (3 seconds).

Scheme 23

System Problem

If a system problem occurs and a DTC is stored, the indicators will show the DTC. The first digit is indicated by the number of long (1 second) blinks, and the second digit is indicated by the number of short (0.26 second) blinks. There is a 3 second break between each DTC when there are multiple DTCs.

Scheme 24

Erasing the Driving Position from Memory

1. Press and hold all three driving position memory switch buttons.
2. Turn the ignition switch to ON (II).
3. Continue to hold all three driving position memory switches for more than 5 seconds, and release them in less than 10 seconds.
4. The buzzer will sound for 0.5 seconds to confirm that all driving position data is erased.

'08-10 Touring models

Note. If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A ).
