C0236

C0236 - TCS RPM SIGNAL CIRCUIT MALFUNCTION





The ECM/PCM provides the ABS control module with engine rpm data so that it can determine TCS operation.

DTC PARAMETERS
DTC C0236 will set if the following conditions exist:
^ The engine rpm circuit is open or shorted.
^ The EBTCM does not receive an rpm input signal one second after engine has been started
When this trouble code set the EBTCM will disable traction control.

DIAGNOSTIC AIDS
Inspect wiring, connectors, and components for the following:
^ Proper connection
^ Backed-out terminals
^ Broken connector locks
^ Corrosion in connectors/terminals
^ Burned, chafed, or pinched wiring
^ A broken wire inside the insulation
^ Loose components

Possible causes for DTC C0236 to set:
^ Open in the delivered rpm circuit
^ The delivered rpm circuit shorted to ground or voltage
^ Communication frequency problem
^ Communication duty cycle problem
^ The delivered rpm circuit has a wiring problem, terminal corrosion, or poor connections
^ EBTCM not receiving information from PCM/ECM
^ A broken wire inside the insulation
