I have bought and installed a new rcm and, though I haven’t opened it to see what happens, the car will still die right after start.
Have you ever seen the "start error" on the dash display?
"Connected to the SKREEM is a Sentry Key Antenna Ring which surrounds the ignition lock cylinder. When the ignition is switched on, the Sentry Key Antenna Ring is sup- plied with power. A data block is transmitted inductively via the Sentry Key Antenna Ring to the SKREEM and then on to the Powertrain Control Module. If the antenna ring data block content is invalid or if vehicle battery power is too low to build up enough power for the antenna ring, the Powertrain Control Module will not receive the proper signal. This is displayed with the message “Start Error” in the Instrument Cluster."
Have you measured this?
"SKREEM TERMINATION
With the ignition off.
Measure the resistance of the SKREEM CAN C Bus termination by back probing the CAN C Bus (+) circuit to the CAN C Bus (-) circuit at the SKREEM C2 harness connector.
Is the resistance between 110 and 130 ohms?" C2 is just a data connection. Are those wires good? Not crushed anywhere?
Or the connectivity between SKREEM and PCM?
"CAN C BUS (-) CIRCUIT OPENWith the ignition off.
Measure the resistance of the CAN C Bus (-) circuit from the SKREEM C2 pin 1 harness connector to the PCM C4 pin 11 harness connector. Also C2 pin 2 to PCM C4 pin 1.
Is the resistance below 5.0 ohms?"
Is the ground near the SKREEM tight?
