System Will Not Operate
- Check for forward/rearward operation of recliner. If not operable, check for an open or loose circuit breaker mounted in board on the relay bank in cavity No. 15.
- Check for continuity between 2-way connector under driver's seat and pin No. 1 at control module 10-way connector. See Fig 1
and Fig 2
.
- Check for continuity between 2-way connector under driver's seat and pin No. 6 at control module 10-way connector.
- Check for any movement of the seat by operating the seat switch. If movement the circuit is good into the control module.
- No movement check for an open or loose fuse in cavity No. 15 of the fuse block.
- Check for battery voltage to pin No. 3 of driver's power seat switch.
- If battery is good, check for continuity of driver's power seat switch. Check power memory seat switch continuity. See Fig 1
.
- Check that all connectors are securely plugged into control module under driver's seat with no terminal push outs.
- No correctable faults are found in the previous steps. The battery voltage and ground circuits are good into the control module. There is battery voltage through the seat switch to the control module. Then replace the control module.
- If the control module must be replaced, open it and observe the non-relay side of the printed circuit board. The module may be damaged by an intermittent short on the inside of the recliner switch. If a trace is burnt open near the 10-way connector, may be caused by the recliner switch. See Fig 3
.
- If module is burnt, remove recliner switch. Open the switch and observe the movable contacts staking at the staked end. If the contact, arm can be rotated, by a sideways motion, the switch must be replaced. This will prevent the new control module from damaged by the switch.
