3.
Remove the tape covering the corrugated harness protector. The length to be uncovered is from behind the battery to where the harness splits
behind the engine.
4.
Isolate the green/black stripe wire in the harness. Follow its length and find the 2 taped splice connections. Remove the tape and inspect the
splices. If the splices or the wires look corroded, cut the bad section out and solder in new wire using proper soldering techniques and rosin core,
(electronic grade) solder. If the splices appear to be in good condition, re-solder the splices to ensure a good electrical connection. Solder in an
additional ground wire to the splice connection nearest to the ISC motor and connect it to the forward bulkhead ground.
5.
Using electrical tape, securely insulate the newly soldered splices. Insert the harness wires into the corrugated protector and retape its entire length.
Note:
Make certain the connections are securely insulated.
6.
Install the battery and reconnect the positive (+) terminal first.
7.
Reprogram the radio station presets. Start and run the engine for 5 minutes so the ECM can develop (relearn) the base idle conditions.
Note:
After completing this ground repair procedure, technicians may find the ISC and/or TPS adjustments are necessary.
8.
Test drive the vehicle to ensure a normal idle condition and that DTC 15 does not reappear.
