The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

There have been a number of returned SDMs and calls to TAC for problems that occurred when reprogramming the SDM. Here are some tips regarding SDM reprogramming.

1. The battery voltage needs to be in the normal operating range during the entire programming process. If the battery is weak, make sure to fully charge the battery prior programming.
2. Do not try to reprogram the SDM with current codes (DTCs) (history DTCs are OK), address the codes using the appropriate SI document. If an SDM is reprogrammed with current faults, other DTCs in addition to the original DTC will be set.
3. If the airbag light is blinking and there are current DTCs; address the codes using the appropriate SI document. The SDM setup can not be completed until all the current SDM DTCs are cleared.
4. If the airbag light is blinking continuously with no codes, the SDM is ready to be set up. Complete the setup procedure in the Tech 2. If after successfully completing the SDM setup procedure and the airbag lamp is still blinking, complete the Rollover Sensor setup procedure on the Tech 2.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
