Testing (Non-DRL Equipped)

  1. Turn ignition switch to OFF position. Disconnect CCM connector C1. Using DVOM, check for continuity between CCM connector C1 terminal A8 and ground. If continuity is present, remove ground from CCM connector C1 terminal A8. If continuity is not present, go to next step.
  2. Turn ignition switch to OFF position. Check for poor connections at CCM connector. If connections are okay, reconnect CCM connector and all other components. Clear DTCs and check if DTC resets. If DTC resets, replace CCM. If DTC does not reset, problem may be intermittent. Try to recreate fault while performing test by wiggling wiring and connectors. Check for poor connections at all connectors that may be causing intermittent condition.
