Truck ate my pcm and starter

Ok i went home checked all the wires and pushed all the connectors in tight the p1283 came up and two for the pcm came up < p0603-continuous powertrain control module keep alive memory (KAM) Error> and < p0605-powertrain control module read only memory (ROM) Error> do either of these codes mean my pcm is toast or a bad wire somewhere? O and i finished off the second new starter last night after about 5 cranks.

p0603 is common when the batteries are disconnected. no worry.

Are they new starters or re-mans. Remans can be bad right out of the box.

DTC 0605 exists only when there has been an internal failure of the PCM

Clear the code and rescan to be sure.

The onboard computer, or Powertrain Control Module (PCM),is the brains of the engine control system, so when the brain is not functioning correctly neither is the engine or anything else that the microprocessor controls - which may include the charging system, transmission, various emission controls and communications with other onboard control modules. Once a diagnosis has been made (and we emphasize the word diagnosis), then and only then should the PCM be replaced.

Onboard Diagnostic (OBD II) diagnostic trouble codes that typically indicate a fault with the powertrain control module include:


P0600....Serial Communication Link

P0601....Internal Control Module Memory Check Sum Error

P0602....Control Module Programming Error

P0603....Internal Control Module Keep Alive Memory (KAM) Error

P0604....Internal Control Module Random Access Memory (RAM) Error

P0605....Internal Control Module Read Only Memory (ROM) Error

P0606....ECM/PCM Processor

P0607....Control Module Performance

P0608....Control Module VSS Output 'A'

P0609....Control Module VSS Output 'B'

P0610....Control Module Vehicle Options Error


If you see any of these codes when diagnosing the vehicle with a code reader or scan tool, it may mean the PCM has failed and must be replaced. Additional diagnostic tests will usually be necessary to confirm the problem is really the powertrain control module and NOT something else. Refer to the OEM diagnostic charts for what these tests are. Usually it involves checking certain inputs to the PCM to see if it outputs the correct response. No response or an incorrect response usually means the PCM is defective and needs to be replaced.
