Step | Action | Value(s) | Yes | No |
|---|---|---|---|---|
1 | Was the entire Data Link Connector (DLC) system check performed? | -- | ||
2 | Use a J 39200 digital multimeter (DMM) in order to measure the voltage between B+ and DLC terminal 5. Is the voltage within the specified range? | B+ (9-14 V) | ||
3 | Inspect for a proper connection of the scan tool to the DLC. Is the connection OK between the scan tool and the DLC? | -- | ||
4 | Repair the poor connection or open in circuit 1550 between the DLC and S211. Has the repair been made? | -- | -- | |
5 | Use the scan tool in order to establish communication with the PCM on a different vehicle. Can communication be established with the scan tool? | -- | ||
6 | Repair the poor connection between the DLC and the scan tool. Is the repair complete? | -- | -- | |
7 |
Can the scan tool communicate with the PCM? | -- | ||
8 | Determine if the scan tool is malfunctioning. Refer to the scan tool instruction manual for additional information. Is the action complete? | -- | -- | |
9 | If malfunction is not present or intermittent, inspect the PCM connector for a poor connection, short to B+, or short to ground in CKT 1807. Repair as necessary. Is the action complete? | -- | -- | |
10 |
Is the resistance the same as the specified value? | Infinite | ||
11 |
Is the voltage less than the specified value? | 1 V | ||
12 | Repair the short to ground in CKT 1807. Is the repair complete? | -- | -- | |
13 | Check continuity in circuit 1807 between the DLC terminal 2 and the PCM connector C1 terminal 59. Is there continuity? | -- | Go to Powertrain On Board Diagnostic (OBD) System Check in Engine Controls | |
14 |
Is the repair complete? | -- | -- | |
15 | Repair the poor connection or an open in CKT 1807. Is the repair complete? | -- | -- | |
16 |
Is the action complete? | -- | -- |
