Default 2005 GTO PCM Swap warning:

GM screwed up SOME of the GTO PCM's. If you try to swap your 05 GTO PCM, and it won't take, read the following:

ECM/PIM Incorrect Security Codes - keywords code linking PCM program replacement #PIC3656 - (Aug 18, 2005)
ECM / PIM Incorrect Security Codes
2005 Pontiac GTO

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

Condition/Concern:
Information for ECM / PIM Incorrect Security Codes

Recommendation/Instructions:
From Start of Production Model Year 05 we have an additional 4 digit immobilizer code requirement, which must be applied to reset a ECM or PIM when either one is replaced. Plant DVT randomly generates the immobilizer code from start of production was ignoring the first numeral in the code if this was a zero, in fact if the first two or three numbers were zero, it would ignore all leading zeros, and assign a three or two or one digit code. Tech 2 searches for a 4 digit code, and when it doesn't find it, reports it as an invalid immobilizer code. This has been corrected as of the breakpoint given below, when programming was changed so that random number generation commences from 1,000. Vehicles with this concern have been identified by being all with leading zeros, and have been listed by VIN.

Field Recommendation:

This will not have any impact on the operation of the vehicle unless either the ECM or PIM need to be replaced, in which case the immobilizer code necessary to achieve a reset will be unachievable. If either a ECM or PIM need to be replaced in these vehicles it will be necessary to replace both at the same time and use the existing immobilizer code. When entering the immobilizer code with the Tech 2 the zeros are recognized.



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.

Default Security PIN code location 04-06

06-08-47-003 is the GM global connect service message, not sure if alldata or shopkey have this information. The PIN is located right on the BCM under the passenger side IP near the HVAC blower housing. Its on a smaller label. hope this helps. This is for 04-06
