Test H: Passive Anti-Theft System Module Does Not Respond To Scan Tool
- Turn ignition switch to LOCK position. Disconnect PATS module harness connector C229. See Figure
. Inspect harness connector for loose, damaged or corroded terminals. If problem does not exist, go to next step. If problem exists, repair as necessary and retest system.
- Connect PATS module harness connector C229. Connect NGS tester to DLC. Turn ignition switch to RUN position. Perform data link diagnostic procedure. See DATA LINK DIAGNOSTIC TEST
under SELF-DIAGNOSTIC SYSTEM. If NGS tester responds with PATS: NO RESPONSE ON CKT914 (BUS +), go to next step. If NGS tester does not respond with PATS: NO RESPONSE ON CKT914 (BUS +), go to step 4
.
- Turn ignition switch to LOCK position. Disconnect NGS tester. Disconnect PATS module harness connector C229. Measure resistance in Tan/Orange wire between terminal No. 6 at PATS module harness connector C229 and terminal No. 2 at DLC. See Figure
and Fig 1
. If resistance is 5 ohms or less, replace PATS module. If resistance is greater than 5 ohms, repair open in Tan/Orange wire.
- Turn ignition switch to LOCK position. Disconnect NGS tester. Disconnect PATS module harness connector C229. Measure resistance in Pink/Light Blue wire between terminal No. 5 at PATS module harness connector C229 and terminal No. 10 at DLC. See Figure
and Fig 1
. If resistance is 5 ohms or less, replace PATS module. If resistance is greater than 5 ohms, repair open in Pink/Light Blue wire.
