  8. Turn ignition off. Reconnect PATS module 16-pin connector C242 (if equipped). Turn ignition of. Measure voltage between terminal No. 16 (Light Green/Red wire) and terminals No. 2 (Tan/Orange wire) and No. 10 (Pink/Light Blue wire) at DLC. If any reading indicates zero volts, go to step 17). If both readings indicate voltage, go to next step.
  9. Measure voltage between terminal No. 4 (Black wire) and terminals No. 2 (Tan/Orange wire) and No. 10 (Pink/Light Blue wire) at DLC. If any reading indicates voltage, go to next step. If both readings indicate zero volts, go to step 14).
  10. Measure voltage between terminals No. 2 (Tan/Orange wire) and No. 10 (Pink/Light Blue wire) at DLC. If reading indicates voltage, go to next step. If reading indicates zero volts, go to step 16) (if equipped with remote climate control system) or repair wire-to-wire short between Tan/Orange wire and Pink/Light Blue wire (if not equipped with remote climate control system). Retest system for normal operation.
  11. Turn ignition off. Reconnect connector C221. Disconnect 42-pin connector C130 located on left side of engine, above transaxle. Turn ignition on. Measure voltage between terminal No. 16 (Light Green/Red wire) and terminals No. 2 (Tan/Orange wire) and No. 10 (Pink/Light Blue wire) at DLC. If any reading indicates voltage, go to next step. If both readings indicate zero volts, repair short to power in Tan/Orange and Pink/Light Blue wires between connector C130 and connector C221. Retest system for normal operation.
  12. Measure voltage between terminal No. 4 (Pink/Light Blue wire) and terminals No. 2 (Tan/Orange wire) and No. 10 (Pink/Light Blue wire) at DLC. If any reading indicates voltage, go to next step. If both readings indicate zero volts, repair short to ground in Tan/Orange and Pink/Light Blue wires between connector C130 and connector C221. Retest system for normal operation.
  13. Measure voltage between terminals No. 2 (Tan/Orange wire) and No. 10 (Pink/Light Blue wire) at DLC. If reading indicates voltage, replace PCM and retest system for normal operation. If reading indicates zero volts, repair wire-to-wire short between Tan/Orange wire and Pink/Light Blue wire. Retest system for normal operation.
  14. Turn ignition off. Reconnect connector C130. Disconnect PCM connector. Inspect connector for loose, damaged or corroded terminals. Repair connector as necessary and retest system for normal operation. If connector is okay, turn ignition on. Measure voltage between terminal No. 16 (Light Green/Red wire) and terminals No. 2 (Tan/Orange wire) and No. 10 (Pink/Light Blue wire) at DLC. See Figure. If any reading indicates voltage, go to next step. If both readings indicate zero volts, repair Tan/Orange wire and Pink/Light Blue wire between PCM and connector C130. Retest system for normal operation.
  15. Measure voltage between terminal No. 4 (Black wire) and terminals No. 2 (Tan/Orange wire) and No. 10 (Pink/Light Blue wire) at DLC. If any reading indicates voltage, go to next step. If both readings indicate zero volts, repair Tan/Orange wire and Pink/Light Blue wire between PCM and connector C130. Retest system for normal operation.
  16. Measure voltage between terminals No. 2 (Tan/Orange wire) and No. 10 (Pink/Light Blue wire) at DLC. If reading indicates voltage, replace PCM and retest system for normal operation.
