NOTE:
DTC B1522 will be stored if hood is seen as open for 5 consecutive arming cycles. It will also be stored if hood is open during SELF-TEST.
- Turn ignition off. Connect and operate NGS tester according to manufacturer's instructions. Select HOOD_SW PID from RAP PID list. If HOOD_SW PID reads PUNCHD with hood closed, go to next step. If HOOD_SW PID does not read PUNCHD with hood closed, rerun RAP module SELF-TEST.
- Disconnect RAP module connector C336. Check continuity between connector C336 terminal No. 23 (Tan/Light Green wire) and ground. If resistance is more than 10,000 ohms, replace RAP module and retest. If resistance is 10,000 ohms or less, repair or replace hood switch and/or Tan/Light Green wire
