Code 118 - TCS Enable Relay Coil Circuit Shorted To Battery: Notes

Ignition voltage is supplied through ASR/TCS relay. EBTCM is then able to energize the pull-in coil by completing the ground circuit at EBTCM ASR/TCS relay control terminal, supplying power to motors and solenoids.

Code 118 can set after EBTCM commands the ASR/TCS relay on. This test monitors available current and voltage to motors and solenoids. A malfunction will not allow voltage to motors and solenoids, and disables TCS operation.

If code is stored, TCS is disabled and TCS warning light is illuminated. The BRAKE warning light is illuminated, if TCS is active at time of malfunction.

NOTE: Test numbers refer to numbers on diagnostic chart. Use only 10-megohm (minimum) DVOM for all voltage and resistance tests.
  1. Indicates EBTCM is capable of controlling ASR/TCS relay as commanded.
  2. Checks for short to voltage in relay control circuit.
  3. Checks relay coil resistance.
  4. Checks for relay contacts that failed to close.
  5. Checks for possible poor terminal contact at EBTCM.
