Document table of contents
- Record fault codes and update software
- Product Diagnostic (PD) Mode wiggle test
- Perform a Load Test on each vehicle battery
- Inspect power and ground supply to the ECA
- Verify battery voltage and polarity at the ECA
- Load Test the power and ground supply
- Verify repair (Step V)
The procedure records fault data, notes that low batteries or a jump-start can induce the code, and uses Product Diagnostic (PD) Mode to find intermittent wiring in the ECA Power Supply Harness. Each battery is load tested per OEM specifications, and battery voltage at the 2-Way ECA Connector Pin 2 to Pin 1, and Pin 2 to ground, must read within 1.2 volts of battery positive before a five-minute harness load test with the 40-amp fuse installed.
Applicable truck models
This covers Eaton Fuller Advantage Heavy Duty transmissions drawing non-switched power through the 2-Way ECA Connector. The steps inspect the ECA 40-amp in-line fusible link, connector corrosion and pin polarity, replacing the ECA only after the harness and batteries pass. Confirm the applicable chassis with the manufacturer on the Eaton official website.
Who needs this fault code 96 troubleshooting guide
Technicians diagnosing an ECA battery power fault after a jump-start or weak batteries use this sequence to confirm the harness and battery condition before replacing the actuator.
