Initial Inspection and Diagnostic Overview
How to Troubleshoot Circuits at the PCMSpecial Tools Required
- Digital multimeter KS-AHM-32-003 (1) or a commercially available digital multimeter
- Connector test adapter Kit J35616-A
- Pin probe (male) 07ZAJ-RDJA110
- Flat spade probe (male) 07ZAJ-RDJA120
NOTE: The PCM overwrites data and monitors the EVAP system for up to 15 minutes after the ignition switch is turned OFF. Jumping the SCS line after turning the ignition switch OFF cancels this function. Disconnecting the PCM during this function, without jumping the SCS line first, can damage the PCM.
1. With the ignition switch ON (II), connect the HDS to the data link connector (DLC), and go into any of the live data screens.
2. Turn the ignition switch OFF.
3. Exit and then restart the HDS software. Go to the SCS mode and follow the screens to ground the 16PDLC
NOTE: Steps 1 through 3 must be done to protect the powertrain control module (PCM) from damage, or wait at least 15 minutes before disconnecting.
4. Disconnect the PCM connectors and probe the terminals from the terminal side of the connectors.
5. Make sure the connector terminals diameter and select the suitable pin probe (male) and/or flat spade probe (male).
6. Connect one side of the patch cord (A) terminals to the digital multimeter (B), and connect the other side of the patch cord terminals to the pin probe (male) and/or flat spade probe (male) (C).
7. Gently slide the pin probe (male) and/or flat spade probe (male). Into the connector terminals from the terminal side. Do not force the tips into the terminals.
NOTE:
- To get correct results, always use the pin probe (male), and/or flat spade probe (male).
- To prevent damage to the connector terminals, do not insert the test equipment probes, paper clips, or other substitutes as they can damage the terminals. Damaged terminals cause a poor connection and an incorrect measurement.
- Do not puncture the insulation on a wire. Punctures can cause poor or intermittent electrical connections.
