TOOL FAULT CODE 64) (B.20.A.92 - G.30.C.10)

CX840, CX860, CX880

0394.2 - AFTERRUN NOT COMPLETED, DATA INCORRECT (SERVICE TOOL FAULT CODE 64)
Context:
Engine enabled - no restriction on fuel or speed
Cause:
Afterrun monitoring not completed
Possible failure modes:
1. Faulty Main Relay (K-14)
2. Low battery voltage
Solution:
1. Check fuses F-01 and F-38.
A. Replace the fuse if blown. Remove the fault code from the engine ECU memory using the electronic
service tool and check the operation of the engine. If fuse blows again inspect wiring harness for damage.
B. If fuses are okay continue with step 2.
2. Check the battery voltage.
A. If voltage is less than 9.5 Volts, check the battery and charging system. Ensure the battery has the correct
voltage and remove the fault code from the engine ECU memory using the electronic service tool. Operate
the engine, if the fault reoccurs continue with step 3.
B. If the voltage is greater than 9.5 Volts continue with step 3.
3. Check the Main Relay (K-14).
A. Remove the relay and check its operation. If okay continue with step 4.
B. Replace the relay if faulty. Remove the fault code from the engine ECU memory using the electronic
service tool. Operate the engine, if the fault reoccurs continue with step 4.
4. Check the wiring harness.
A. Remove the relay K-14 and check for continuity of the wiring between the engine ECU connector X193
and the relay K-14 holder. Check between the pin 2 of the holder and the pin 27 of X193 and between pin
5 of the holder and pins 3 and 4 of X193. If an open circuit is indicated at any stage repair or replace the
wiring as required.
B. If continuity is good remove the fault code from the ECU memory, using the electronic service tool and
operate the engine. The fault may be intermittent, wiggle test the harness to attempt to induce the fault. If
fault reoccurs repeat step 4. If fault does not occur continue with vehicle operation.
