Park Lamp Switch Circuit Malfunction
Circuit Description
The body control module (BCM) compares the state of the park lamp circuit 9
to the high beam headlamp circuit 1200 and the low beam headlamp circuit 1201.
If the park lamp circuit is grounded/open and either the high beam circuit is
at battery voltage or the low beam circuit is grounded, diagnostic code B2662 will
set.
Conditions for Setting the DTC
| • | Circuit 9 grounded or open |
| • | Conditions present for 1 second |
Diagnostic Aids
| • | Check for poor connection at the BCM. Inspect harness connectors for: |
| • | improper terminal mating |
| • | improperly formed or damaged terminals |
| • | poor terminal-to-wire connection (terminal crimped over wire insulation
and not conductors). |
| • | Inspect the wiring harness for damage. Check for broken or
chafed insulation. |
| • | Check for poor connection at the headlamp switch. |
| • | If fault is suspected to be intermittent, wiggling harness wiring may
help in locating fault. |
