Symptom:
CPA NOT ENGAGED
When Monitored and Set Condition:
CPA NOT ENGAGED
When Monitored:
Continuously with the ignition on.
Set Condition:
If the connector positive assurance lock is not fully engaged, the Front
Control Module will detect battery voltage on the B(+) sense circuit. With voltage present,
the FCM determines that there is a poor connection at connector C5 of the Fuse and Relay
Center.
POSSIBLE CAUSES
FRONT CONTROL MODULE INTERNAL MALFUNCTION
FUSE AND RELAY CENTER INTERNAL MALFUNCTION
INTERMITTENT CONDITION
CONNECTOR POSITIVE ASSURANCE LOCK
TEST
ACTION
APPLICABILITY
1
Turn the ignition on.
With the DRBIII
t, erase the current Front Control Module DTC’s.
Turn the ignition off, wait 10 seconds then turn the ignition on.
With the DRBIII
t, read the current Front Control Module DTC’s.
Does the DRBIII
t display: CPA NOT ENGAGED?
All
Yes
→ Go To 2
No
→ The condition that caused this symptom is currently not present.
Inspect the related wiring harness for a possible intermittent
condition.
Perform BODY VERIFICATION TEST - VER 1.
2
Turn the ignition off.
Disconnect the Front Control Module from the Fuse and Relay Center.
Measure the voltage of the B(+) Sense circuit at the Fuse and Relay Center side of the
FCM connector.
Is the voltage above 10.0 volts?
All
Yes
→ Go To 3
No
→ Replace the Front Control Module.
Perform BODY VERIFICATION TEST - VER 1.
