Checking For Fault Code 16

  1. This checks for direct battery feed to SMEC. Circuit is also memory feed to SMEC. Code 16 with lower battery voltage will turn on power loss/limit light.
  2. Connect DRB-II to engine harness connector. Place system in Sensor Test Mode 07. Display on DRB-II should be within one volt of battery voltage.
  3. If display reads 00, disconnect SMEC 60-pin connector. See Figure. Check voltage at pin No. 41. If voltage is not within one volt of battery voltage, replace SMEC. Before replacing SMEC, ensure terminal in cavity No. 22 is not crushed and makes contact with SMEC pin. If voltage is not as specified, repair open circuit in wiring harness.
