Circuit Description
DTC C1213 tests the state of the ABS (LOW TRACTION) active indicator. DTC C1213 identifies a situation in which the driver could not be warned of a low traction event by the ABS warning indicator or the ABS warning indicator is always on. The EBCM/EBTCM provides a ground through CKT 832 in order to turn the ABS warning indicator on. If the control line CKT 832 is open or shorted to voltage the ABS indicator will always remain off. If the control line CKT 832 is shorted to ground the ABS active indicator remains on when the ignition is in the RUN position.
This code will is use on basic ABS system and will not show up if vehicle is equipped with TCS (Traction Control System).

Conditions For Setting The DTC
DTC C1213 sets only during one of the following conditions:
^ The three second bulb check
^ The indicator turns on.
A malfunction exists if the EBCM/EBTCM cannot control the ABS active (LOW TRACTION) indicator for two seconds.

Action Taken When The DTC Sets
^ A malfunction DTC stores.
^ The ABS does not disable

Conditions for Clearing The DTC
^ The condition responsible for setting the DTC no longer exists and the Scan Tool Clear DTC function is used.
^ 100 drive cycles pass with no DTC detected.

Diagnostic Aids
The following conditions may cause an intermittent malfunction:
^ A poor connection
^ Rubbed-through wire insulation
^ A broken wire inside the insulation
Use the Scan Tool Lamp Test function in order to command the indicator on while looking for an intermittent malfunction in the ABS active (LOW TRACTION) indicator circuitry.
Use the enhanced diagnostic function of the Scan Tool in order to measure the frequency of the malfunction. Refer to the Scan Tool manual or Scan Tool Diagnostics for the procedure.
Thoroughly inspect any circuitry that may be causing the intermittent complaint for the following conditions:
^ Backed out terminals
^ Improper mating
^ Improperly formed or damaged terminals
^ Poor terminal-to-wiring connections
^ Physical damage to the wiring harness

Important: Zero the J39200 test leads before making any resistance measurements.
